OffPDF — 22 offline PDF tools built with Tauri v2 and Rust

[McanKul]

Hey everyone — I built OffPDF because sensitive PDFs should not have to pass through a random upload service.

It is a free, MIT-licensed Tauri v2 desktop app with 22 PDF workflows that run locally and continue to work offline. It covers everyday tasks such as merging, splitting, page organization, compression, OCR, conversion, protection, repair, booklet layout, and text extraction.

Under the hood

• Tauri v2 with a React and TypeScript interface
• Rust commands coordinating qpdf, Poppler, Tesseract, and LibreOffice
• Local process execution with argument arrays and temporary output files
• No account, analytics, telemetry, cloud API, or document uploads
• A restrictive CSP and a local custom protocol in production

The most interesting tradeoff has been packaging several native document engines while keeping the app genuinely offline. The Windows installer is large because it bundles the required engines. The Apple Silicon macOS build bundles qpdf, Poppler, and Tesseract, with LibreOffice remaining optional for Office and PDF/A workflows.

Current state

• Windows x64 installer is available, but it is not code-signed yet
• The Apple Silicon DMG is signed and notarized
• Intel Mac and Linux do not have published packages yet
• The visual editor is still being stabilized

Contributors are welcome

The project just received its first outside contributions, and more help would be genuinely welcome. A scoped task is currently available:

• Poster page tiling calculation tests

There are also broader open issues and a short contributing guide. Pull requests should target the development branch.

If you have shipped local binaries with Tauri, I would especially value feedback on how you balance offline capability against installer size and cross-platform packaging.
