Your files never leave your computer. OffPDF processes documents locally and always writes the result to a new file, leaving the original untouched.
OffPDF is a free, MIT-licensed desktop toolbox for everyday PDF work. It uses local engines such as qpdf, Poppler, Tesseract, and LibreOffice, with no cloud service in the middle.
- Private by design. No uploads, accounts, analytics, telemetry, or remote API.
- Useful offline. Install it once and keep working without a connection.
- One focused toolbox. Organize, convert, compress, OCR, protect, and repair PDFs.
- Open and inspectable. The app and its privacy model are available here under MIT.

| Platform | Package | Status |
|---|---|---|
| Windows x64 | Download from the latest release | Available on GitHub Releases; currently unsigned while Authenticode signing is completed |
| macOS 11+ · Apple Silicon | Download from the latest release | Signed and notarized |
| Intel Mac / Linux | Build from source | No published package yet |
The Windows installer is large because it includes the local engines needed to keep its core workflows offline. The macOS build bundles qpdf, Poppler, and Tesseract; LibreOffice is optional and only needed for Office and PDF/A tools. Until Authenticode signing is complete, the Windows package is distributed only through GitHub Releases and is not linked from offpdf.com.
All published binaries are available on the Releases page.
See the code signing policy for how official release artifacts are built, approved, and verified.
- Documents are processed by local binaries on your machine.
- Preview, search, and editing may pass locally generated page data, thumbnails, or extracted text to the bundled interface. This data stays inside the app.
- There is no account system, cloud sync, analytics, telemetry, or remote API.
- The production app uses Tauri's local custom protocol and a restrictive CSP.
- Auto-update is not enabled.
