Frequently asked questions about pdftract.

+

Table of Contents

+ +
+

General

+

What is pdftract?

+

pdftract is a command-line tool and library for extracting text, structure, and content from PDF files. It combines vector text extraction with OCR fallback to handle both well-formed and problematic PDFs. pdftract is written in Rust and provides Python bindings for programmatic use.

+

See the Introduction for a complete overview.

+

What’s the difference between extract and extract_text?

+
    +
  • +

    extract: The primary command that produces structured JSON output with blocks, spans, metadata, and provenance information. Use this when you need the full extraction with layout, reading order, and confidence scores.

    +
    • +
  • +

    extract_text: A simplified command that outputs plain text only. Use this for quick text extraction when you don’t need the structured JSON output.

    +
    • +
+

Example:

+
# Full structured extraction
+pdftract extract document.pdf -o output.json
+
+# Plain text only
+pdftract extract_text document.pdf -o output.txt
+
+

Does pdftract execute JavaScript embedded in PDFs?

+

No. pdftract never executes JavaScript embedded in PDFs. JavaScript is detected during parsing for security analysis, but it is never executed. This design prevents malicious PDFs from exploiting JavaScript vulnerabilities.

+

If you need to analyze JavaScript in PDFs, pdftract can detect and report its presence, but execution must be done separately with appropriate sandboxing.

+

How do I cite an extracted snippet?

+

The JSON output from pdftract extract includes provenance information for each text block:

+
{
+  "blocks": [{
+    "spans": [{
+      "text": "Example snippet",
+      "bbox": [100.0, 200.0, 250.0, 215.0],
+      "page": 3,
+      "confidence": 0.98
+    }]
+  }],
+  "metadata": {
+    "path": "/path/to/document.pdf",
+    "fingerprint": "sha256:abc123...",
+    "extracted_at": "2026-05-25T12:00:00Z"
+  }
+}
+
+

For academic citations, include:

+
    +
  • Document path and fingerprint
    • +
  • Page number (from the page field)
    • +
  • Extraction timestamp
    • +
  • The pdftract version used
    • +
+
+

Installation and Setup

+

How do I install pdftract?

+

See the Installation guide for complete instructions. Quick summary:

+

With cargo (Rust toolchain):

+
cargo install pdftract
+
+

With pip (Python bindings):

+
pip install pdftract
+
+

Pre-built binaries: Download from the releases page.

+

How do I run pdftract behind a corporate proxy?

+

pdftract doesn’t have built-in proxy support, but you can use the HTTP serve mode with a reverse proxy:

+
    +
  1. Start pdftract in serve mode:
    2. +
+
pdftract serve --port 8080
+
+
    +
  1. +

    Configure your reverse proxy (nginx, Apache, etc.) to handle authentication and SSL termination.

    +
    2. +
  2. +

    Access pdftract through your proxy endpoint.

    +
    3. +
+

See Advanced Topics: HTTP Serve for deployment guidance.

+

What are the system requirements?

+
    +
  • OS: Linux, macOS, or Windows
    • +
  • Rust: 1.70+ (if building from source)
    • +
  • Python: 3.8+ (for Python bindings)
    • +
  • OCR (optional): Tesseract 4.0+ for OCR fallback
    • +
  • Memory: 512 MB minimum for typical PDFs; more for large documents
    • +
+
+

Usage

+

Why is my PDF returning broken_vector?

+

The broken_vector classification means the PDF’s text layer is unreliable or missing. Common causes:

+
    +
  • Invisible text overlay: Text with rendering mode 3 (invisible) overlaid on a raster image
    • +
  • Missing ToUnicode CMap: Font lacks character-to-Unicode mapping
    • +
  • Encoding corruption: Character encodings don’t match the actual glyphs
    • +
+

Solution: pdftract automatically routes broken_vector pages to the OCR pipeline (Phase 5.5). If you see broken_vector without OCR output, check that OCR is enabled:

+
# Verify OCR is available
+pdftract doctor tesseract-langs
+
+# Enable OCR explicitly if needed
+pdftract extract document.pdf --enable-ocr
+
+

See Troubleshooting: Broken Vector for more details.

+

Why is OCR slow?

+

OCR performance depends on several factors:

+
    +
  • Image resolution: Higher DPI images take longer to process
    • +
  • Tesseract version: Version 4.0+ is significantly faster than 3.x
    • +
  • Language data: Additional language packs increase processing time
    • +
  • Hardware: CPU-bound; more cores help with batch processing
    • +
+

To speed up OCR:

+
# Reduce DPI (trade-off: accuracy)
+pdftract extract document.pdf --ocr-dpi 200
+
+# Use fewer languages
+pdftract extract document.pdf --ocr-lang eng
+
+# Disable OCR for vector-only PDFs
+pdftract extract document.pdf --disable-ocr
+
+

How do I extract text from a specific page range?

+

Use the --pages flag:

+
# Single page
+pdftract extract document.pdf --pages 5
+
+# Range
+pdftract extract document.pdf --pages 1-10
+
+# Multiple ranges
+pdftract extract document.pdf --pages 1-5,10,15-20
+
+# All pages from page 5 onward
+pdftract extract document.pdf --pages 5-
+
+

How do I extract images from a PDF?

+

pdftract automatically detects and records image XObjects during content stream processing. The output JSON includes image metadata:

+
{
+  "images": [{
+    "bbox": [100.0, 200.0, 400.0, 500.0],
+    "xobject_ref": "5 0 R",
+    "name": "Im1"
+  }]
+}
+
+

For actual image extraction, use the serve mode with the /images endpoint or write a custom script using the Python SDK.

+

Can I process multiple PDFs at once?

+

Yes, use shell wildcards or write a batch script:

+
# Process all PDFs in a directory
+for file in *.pdf; do
+    pdftract extract "$file" -o "output/$(basename "$file" .json)"
+done
+
+# With parallel processing (GNU parallel)
+ls *.pdf | parallel -j 4 pdftract extract {} -o output/{/.}.json
+
+
+

Configuration

+

How do I add a custom profile?

+

Create a YAML file defining your profile:

+
# custom-profile.yaml
+name: my_custom
+description: "Custom extraction profile"
+
+extraction:
+  preserve_tables: true
+  preserve_columns: true
+  ocr_fallback: true
+
+output:
+  format: json
+  include_provenance: true
+  confidence_threshold: 0.7
+
+

Then use it:

+
pdftract extract document.pdf --profile custom-profile.yaml
+
+

See Custom Profiles for complete documentation.

+

How do I adjust OCR accuracy?

+

Adjust Tesseract parameters via environment variables or the OCR configuration:

+
# Set OCR engine mode
+export TESSERACT_OEM=1  # LSTM only
+export TESSERACT_PSM=6  # Assume single column block of text
+
+# Adjust page segmentation mode
+pdftract extract document.pdf --tesseract-psm 6
+
+

Higher accuracy settings may slow down processing. See OCR Configuration for details.

+

How do I disable OCR for faster processing?

+

If you know your PDFs have reliable text layers:

+
pdftract extract document.pdf --disable-ocr
+
+

Or set a confidence threshold to skip low-confidence text:

+
pdftract extract document.pdf --min-confidence 0.9
+
+

What are confidence scores and how do I use them?

+

Each text span has a confidence score (0.0 to 1.0):

+
    +
  • 1.0: High confidence (ToUnicode CMap lookup succeeded)
    • +
  • 0.3: Medium confidence (encoding + AGL fallback)
    • +
  • 0.0: No confidence (PositionHint mode or failed resolution)
    • +
+

Filter by confidence:

+
pdftract extract document.pdf --min-confidence 0.5
+
+

Or filter in post-processing using jq:

+
pdftract extract document.pdf | jq '.blocks[].spans[] | select(.confidence > 0.5)'
+
+
+

Output and Formats

+

How do I get output in Markdown format?

+

Use the --format flag:

+
pdftract extract document.pdf --format markdown -o output.md
+
+

The Markdown output preserves headings, lists, tables, and code blocks where detected.

+

How do I preserve table structure?

+

pdftract includes table detection (Phase 4.2). Ensure table preservation is enabled:

+
pdftract extract document.pdf --preserve-tables
+
+

Tables are output with structured cell information:

+
{
+  "type": "table",
+  "rows": 3,
+  "columns": 4,
+  "cells": [...]
+}
+
+

Can I extract metadata from PDFs?

+

Yes, metadata is automatically extracted and included in the output:

+
{
+  "metadata": {
+    "title": "Document Title",
+    "author": "Author Name",
+    "subject": "Subject",
+    "keywords": ["keyword1", "keyword2"],
+    "creator": "Application",
+    "producer": "PDF Producer",
+    "creation_date": "2026-01-01T00:00:00Z",
+    "modified_date": "2026-05-25T12:00:00Z"
+  }
+}
+
+

How do I handle password-protected PDFs?

+

Provide the password via the --password flag:

+
pdftract extract document.pdf --password secret123
+
+

For security, avoid passing passwords on the command line in production. Use environment variables or a config file:

+
export PDFTRACT_PASSWORD=secret123
+pdftract extract document.pdf
+
+
+

Troubleshooting

+

Why is extraction failing with an error?

+

Check the error message and consult the Troubleshooting Guide. Common issues:

+
    +
  • Encrypted PDFs: Use --password to decrypt
    • +
  • Corrupted PDFs: pdftract attempts recovery; check diagnostics
    • +
  • Missing dependencies: Verify Tesseract and language packs are installed
    • +
+

Run diagnostics:

+
pdftract doctor
+
+

Why is my output empty or incomplete?

+

Possible causes:

+
    +
  1. No text layer: PDF may be image-only. Enable OCR.
    2. +
  2. Encoding issues: Check diagnostics for FONT_GLYPH_UNMAPPED warnings
    3. +
  3. Page range issue: Verify your --pages argument
    4. +
  4. Confidence filter: Lower --min-confidence if set too high
    5. +
+

Check diagnostics output:

+
pdftract extract document.json --verbose
+
+

How do I debug extraction issues?

+

Enable verbose output and diagnostics:

+
# Full diagnostic output
+pdftract extract document.pdf --verbose --diagnostics
+
+# Save diagnostics for analysis
+pdftract extract document.pdf --diagnostics -o diagnostics.json
+
+

Common diagnostic codes:

+
    +
  • FONT_GLYPH_UNMAPPED: Glyph couldn’t be mapped to Unicode
    • +
  • STREAM_DECODE_ERROR: Stream decompression failed
    • +
  • STRUCT_INVALID_TYPE: Unexpected object type
    • +
+

See Diagnostics Reference for a complete list.

+

Why does extraction use so much memory?

+

Memory usage depends on:

+
    +
  • PDF size: Larger PDFs with many images use more memory
    • +
  • OCR: Tesseract loads image data into memory
    • +
  • Output buffering: Large JSON outputs are buffered in memory
    • +
+

To reduce memory usage:

+
# Process page-by-page
+for page in {1..100}; do
+    pdftract extract document.pdf --pages $page -o "page-$page.json"
+done
+
+# Disable OCR if not needed
+pdftract extract document.pdf --disable-ocr
+
+# Stream output (if supported)
+pdftract extract document.pdf --stream-output
+
+

Phase 7 Placeholders

+

The following fields are included in the schema for forward compatibility but are not yet populated in Phase 6. They will be populated in Phase 7:

+
    +

    • +
+

These fields are present in the schema as empty arrays or null values, allowing consumers to pre-allocate space for future data without breaking when Phase 7 features are added.

+

Diagnostics

+

Diagnostic messages provide visibility into extraction quality and issues:

+
+ + + + + + + + +
SeverityDescription
WARNWarning - extraction succeeded but with potential quality issues (e.g., low coverage suggesting scanned content).
ERRORError - extraction failed for a specific page or region.
+
+

Example diagnostics:

+
[
+  "WARN: page 3: low coverage (54%) - possible scanned content",
+  "ERROR: page 7: failed to extract - corrupt content stream"
+]
+
+

Coordinate System

+

All bbox values use PDF user-space coordinates:

+
    +
  • Units: PDF points (1/72 inch, approximately 0.353 mm)
    • +
  • Origin: Lower-left corner of the page (x=0, y=0)
    • +
  • Format: [x0, y0, x1, y1] where (x0, y0) is bottom-left and (x1, y1) is top-right
    • +
+

Example: For a US Letter page (8.5 × 11 inches):

+
    +
  • Width: 612 points (8.5 × 72)
    • +
  • Height: 792 points (11 × 72)
    • +
  • Full page bbox: [0, 0, 612, 792]
    • +
+

Schema Validation

+

Per INV-11, all JSON output must validate against the schema. CI runs a schema validation step on every fixture:

+
# Python validation example
+pip install jsonschema
+jsonschema -i output.json docs/schema/v1.0/pdftract.schema.json
+
+

Frequently asked questions about pdftract.

+
Table of Contents

+
+

+
General

+
What is pdftract?

+
pdftract is a command-line tool and library for extracting text, structure, and content from PDF files. It combines vector text extraction with OCR fallback to handle both well-formed and problematic PDFs. pdftract is written in Rust and provides Python bindings for programmatic use.

+
See the Introduction for a complete overview.

+
What’s the difference between extract and extract_text?

+
    
+
  • 
+
    extract: The primary command that produces structured JSON output with blocks, spans, metadata, and provenance information. Use this when you need the full extraction with layout, reading order, and confidence scores.
    
+
    • 
+
  • 
+
    extract_text: A simplified command that outputs plain text only. Use this for quick text extraction when you don’t need the structured JSON output.
    
+
    • 
+

+
Example:

+
# Full structured extraction
+pdftract extract document.pdf -o output.json
+
+# Plain text only
+pdftract extract_text document.pdf -o output.txt
+

+
Does pdftract execute JavaScript embedded in PDFs?

+
No. pdftract never executes JavaScript embedded in PDFs. JavaScript is detected during parsing for security analysis, but it is never executed. This design prevents malicious PDFs from exploiting JavaScript vulnerabilities.

+
If you need to analyze JavaScript in PDFs, pdftract can detect and report its presence, but execution must be done separately with appropriate sandboxing.

+
How do I cite an extracted snippet?

+
The JSON output from pdftract extract includes provenance information for each text block:

+
{
+  "blocks": [{
+    "spans": [{
+      "text": "Example snippet",
+      "bbox": [100.0, 200.0, 250.0, 215.0],
+      "page": 3,
+      "confidence": 0.98
+    }]
+  }],
+  "metadata": {
+    "path": "/path/to/document.pdf",
+    "fingerprint": "sha256:abc123...",
+    "extracted_at": "2026-05-25T12:00:00Z"
+  }
+}
+

+
For academic citations, include:

+
    
+
  • Document path and fingerprint
    • 
+
  • Page number (from the page field)
    • 
+
  • Extraction timestamp
    • 
+
  • The pdftract version used
    • 
+

+

+
Installation and Setup

+
How do I install pdftract?

+
See the Installation guide for complete instructions. Quick summary:

+
With cargo (Rust toolchain):

+
cargo install pdftract
+

+
With pip (Python bindings):

+
pip install pdftract
+

+
Pre-built binaries: Download from the releases page.

+
How do I run pdftract behind a corporate proxy?

+
pdftract doesn’t have built-in proxy support, but you can use the HTTP serve mode with a reverse proxy:

+
    
+
  1. Start pdftract in serve mode:
    2. 
+

+
pdftract serve --port 8080
+

+
    
+
  1. 
+
    Configure your reverse proxy (nginx, Apache, etc.) to handle authentication and SSL termination.
    
+
    2. 
+
  2. 
+
    Access pdftract through your proxy endpoint.
    
+
    3. 
+

+
See Advanced Topics: HTTP Serve for deployment guidance.

+
What are the system requirements?

+
    
+
  • OS: Linux, macOS, or Windows
    • 
+
  • Rust: 1.70+ (if building from source)
    • 
+
  • Python: 3.8+ (for Python bindings)
    • 
+
  • OCR (optional): Tesseract 4.0+ for OCR fallback
    • 
+
  • Memory: 512 MB minimum for typical PDFs; more for large documents
    • 
+

+

+
Usage

+
Why is my PDF returning broken_vector?

+
The broken_vector classification means the PDF’s text layer is unreliable or missing. Common causes:

+
    
+
  • Invisible text overlay: Text with rendering mode 3 (invisible) overlaid on a raster image
    • 
+
  • Missing ToUnicode CMap: Font lacks character-to-Unicode mapping
    • 
+
  • Encoding corruption: Character encodings don’t match the actual glyphs
    • 
+

+
Solution: pdftract automatically routes broken_vector pages to the OCR pipeline (Phase 5.5). If you see broken_vector without OCR output, check that OCR is enabled:

+
# Verify OCR is available
+pdftract doctor tesseract-langs
+
+# Enable OCR explicitly if needed
+pdftract extract document.pdf --enable-ocr
+

+
See Troubleshooting: Broken Vector for more details.

+
Why is OCR slow?

+
OCR performance depends on several factors:

+
    
+
  • Image resolution: Higher DPI images take longer to process
    • 
+
  • Tesseract version: Version 4.0+ is significantly faster than 3.x
    • 
+
  • Language data: Additional language packs increase processing time
    • 
+
  • Hardware: CPU-bound; more cores help with batch processing
    • 
+

+
To speed up OCR:

+
# Reduce DPI (trade-off: accuracy)
+pdftract extract document.pdf --ocr-dpi 200
+
+# Use fewer languages
+pdftract extract document.pdf --ocr-lang eng
+
+# Disable OCR for vector-only PDFs
+pdftract extract document.pdf --disable-ocr
+

+
How do I extract text from a specific page range?

+
Use the --pages flag:

+
# Single page
+pdftract extract document.pdf --pages 5
+
+# Range
+pdftract extract document.pdf --pages 1-10
+
+# Multiple ranges
+pdftract extract document.pdf --pages 1-5,10,15-20
+
+# All pages from page 5 onward
+pdftract extract document.pdf --pages 5-
+

+
How do I extract images from a PDF?

+
pdftract automatically detects and records image XObjects during content stream processing. The output JSON includes image metadata:

+
{
+  "images": [{
+    "bbox": [100.0, 200.0, 400.0, 500.0],
+    "xobject_ref": "5 0 R",
+    "name": "Im1"
+  }]
+}
+

+
For actual image extraction, use the serve mode with the /images endpoint or write a custom script using the Python SDK.

+
Can I process multiple PDFs at once?

+
Yes, use shell wildcards or write a batch script:

+
# Process all PDFs in a directory
+for file in *.pdf; do
+    pdftract extract "$file" -o "output/$(basename "$file" .json)"
+done
+
+# With parallel processing (GNU parallel)
+ls *.pdf | parallel -j 4 pdftract extract {} -o output/{/.}.json
+

+

+
Configuration

+
How do I add a custom profile?

+
Create a YAML file defining your profile:

+
# custom-profile.yaml
+name: my_custom
+description: "Custom extraction profile"
+
+extraction:
+  preserve_tables: true
+  preserve_columns: true
+  ocr_fallback: true
+
+output:
+  format: json
+  include_provenance: true
+  confidence_threshold: 0.7
+

+
Then use it:

+
pdftract extract document.pdf --profile custom-profile.yaml
+

+
See Custom Profiles for complete documentation.

+
How do I adjust OCR accuracy?

+
Adjust Tesseract parameters via environment variables or the OCR configuration:

+
# Set OCR engine mode
+export TESSERACT_OEM=1  # LSTM only
+export TESSERACT_PSM=6  # Assume single column block of text
+
+# Adjust page segmentation mode
+pdftract extract document.pdf --tesseract-psm 6
+

+
Higher accuracy settings may slow down processing. See OCR Configuration for details.

+
How do I disable OCR for faster processing?

+
If you know your PDFs have reliable text layers:

+
pdftract extract document.pdf --disable-ocr
+

+
Or set a confidence threshold to skip low-confidence text:

+
pdftract extract document.pdf --min-confidence 0.9
+

+
What are confidence scores and how do I use them?

+
Each text span has a confidence score (0.0 to 1.0):

+
    
+
  • 1.0: High confidence (ToUnicode CMap lookup succeeded)
    • 
+
  • 0.3: Medium confidence (encoding + AGL fallback)
    • 
+
  • 0.0: No confidence (PositionHint mode or failed resolution)
    • 
+

+
Filter by confidence:

+
pdftract extract document.pdf --min-confidence 0.5
+

+
Or filter in post-processing using jq:

+
pdftract extract document.pdf | jq '.blocks[].spans[] | select(.confidence > 0.5)'
+

+

+
Output and Formats

+
How do I get output in Markdown format?

+
Use the --format flag:

+
pdftract extract document.pdf --format markdown -o output.md
+

+
The Markdown output preserves headings, lists, tables, and code blocks where detected.

+
How do I preserve table structure?

+
pdftract includes table detection (Phase 4.2). Ensure table preservation is enabled:

+
pdftract extract document.pdf --preserve-tables
+

+
Tables are output with structured cell information:

+
{
+  "type": "table",
+  "rows": 3,
+  "columns": 4,
+  "cells": [...]
+}
+

+
Can I extract metadata from PDFs?

+
Yes, metadata is automatically extracted and included in the output:

+
{
+  "metadata": {
+    "title": "Document Title",
+    "author": "Author Name",
+    "subject": "Subject",
+    "keywords": ["keyword1", "keyword2"],
+    "creator": "Application",
+    "producer": "PDF Producer",
+    "creation_date": "2026-01-01T00:00:00Z",
+    "modified_date": "2026-05-25T12:00:00Z"
+  }
+}
+

+
How do I handle password-protected PDFs?

+
Provide the password via the --password flag:

+
pdftract extract document.pdf --password secret123
+

+
For security, avoid passing passwords on the command line in production. Use environment variables or a config file:

+
export PDFTRACT_PASSWORD=secret123
+pdftract extract document.pdf
+

+

+
Troubleshooting

+
Why is extraction failing with an error?

+
Check the error message and consult the Troubleshooting Guide. Common issues:

+
    
+
  • Encrypted PDFs: Use --password to decrypt
    • 
+
  • Corrupted PDFs: pdftract attempts recovery; check diagnostics
    • 
+
  • Missing dependencies: Verify Tesseract and language packs are installed
    • 
+

+
Run diagnostics:

+
pdftract doctor
+

+
Why is my output empty or incomplete?

+
Possible causes:

+
    
+
  1. No text layer: PDF may be image-only. Enable OCR.
    2. 
+
  2. Encoding issues: Check diagnostics for FONT_GLYPH_UNMAPPED warnings
    3. 
+
  3. Page range issue: Verify your --pages argument
    4. 
+
  4. Confidence filter: Lower --min-confidence if set too high
    5. 
+

+
Check diagnostics output:

+
pdftract extract document.json --verbose
+

+
How do I debug extraction issues?

+
Enable verbose output and diagnostics:

+
# Full diagnostic output
+pdftract extract document.pdf --verbose --diagnostics
+
+# Save diagnostics for analysis
+pdftract extract document.pdf --diagnostics -o diagnostics.json
+

+
Common diagnostic codes:

+
    
+
  • FONT_GLYPH_UNMAPPED: Glyph couldn’t be mapped to Unicode
    • 
+
  • STREAM_DECODE_ERROR: Stream decompression failed
    • 
+
  • STRUCT_INVALID_TYPE: Unexpected object type
    • 
+

+
See Diagnostics Reference for a complete list.

+
Why does extraction use so much memory?

+
Memory usage depends on:

+
    
+
  • PDF size: Larger PDFs with many images use more memory
    • 
+
  • OCR: Tesseract loads image data into memory
    • 
+
  • Output buffering: Large JSON outputs are buffered in memory
    • 
+

+
To reduce memory usage:

+
# Process page-by-page
+for page in {1..100}; do
+    pdftract extract document.pdf --pages $page -o "page-$page.json"
+done
+
+# Disable OCR if not needed
+pdftract extract document.pdf --disable-ocr
+
+# Stream output (if supported)
+pdftract extract document.pdf --stream-output
+

+
