A PDF editor and a PDF SDK on one Rust engine.
The engine is written in Rust with no C or C++ dependencies. The editor is free for everyone, including commercial use, and the SDK is AGPL-3.0 or commercially licensed.
| Extraction for AI PDF to Markdown with reading order, tables and headings kept. Scanned pages get read. |
One engine, every language Rust, Python, Node.js, .NET, Java, C and WebAssembly from the same code. |
Private by design Everything runs on your machine. The editor needs no account and works offline. |
| Forms, PDF/A, signatures AcroForm fill, PDF/A-1b/2b/3b, PAdES signatures, redaction that removes the content. |
Public benchmarks The harness, scorers and per-run results are open: pdfluent-bench. |
For agents too An MCP server that reads, searches and fills local PDFs. |
PDFluent 1.3.0 ranks above every engine on the published opendataloader-bench leaderboard (as of 3 November 2026)*.
*Overall score 0.9168 (quality="auto", keep_furniture=True, Linux) against the engines listed in the benchmark README on 3 November 2026; submitted as pull request #37. Other engines have submissions open that are not yet on the leaderboard.
→ Full tables, all four measures and how to reproduce
The editor is free for everyone, including commercial use, with no account and no subscription. Documents are processed entirely on your device, and the only automatic network request is an update check you can switch off in Settings.
