A PDF text extraction library that gets the hard parts right.
Platform Support
| Platform | Status |
|---|---|
| Linux x86_64 | Fully CI-tested (gating CI on every PR) |
| Linux aarch64 | Fully CI-tested |
| macOS x86_64 | Build-tested; manually smoke-tested per release |
| macOS aarch64 | Build-tested; manually smoke-tested per release |
| Windows x86_64 | Build-tested; manually smoke-tested per release |
Note: Linux is fully CI-tested; macOS and Windows are build-tested and manually smoke-tested per release. See docs/operations/manual-platform-smoke.md for the per-release smoke procedure.

Quickstart
Rust
use pdftract_core::{extract_pdf, ExtractionOptions};
let opts = ExtractionOptions::default();
let doc = extract_pdf("file.pdf", &opts)?;
println!("Extracted {} pages", doc.metadata.page_count);
Python
import pdftract
doc = pdftract.extract("file.pdf")
print(f"Extracted {doc['metadata']['page_count']} pages")
CLI
pdftract extract file.pdf --json result.json # JSON output
pdftract extract file.pdf --text - # Plain text to stdout
pdftract serve --port 8080 # HTTP microservice
What it does
- Correct reading order — layout regions are segmented and sequenced before text is emitted, handling multi-column pages, sidebars, footnotes, and mixed-layout documents
- Font encoding recovery — when
ToUnicodeCMaps are absent, wrong, or incomplete, pdftract works through a layered recovery pipeline: glyph name lookup, font fingerprinting, and glyph outline shape matching - Structure tree extraction — PDF/UA and PDF/A documents encode their logical structure; pdftract reads this directly when present
- Per-page hybrid routing — each page is independently classified and routed to the appropriate pipeline: vector text extraction, full OCR, or assisted OCR
- Structured output with provenance — the primary output is JSON carrying per-span bounding boxes, font name, size, and confidence score
