Coming soonNeeds the desktop app
Some tools work better natively.
A browser tab cannot ship the heavy engines or handle multi-gigabyte files efficiently. These jobs run in the free OffPDF desktop app — the same privacy, with more power.
Get the desktop appOCR (make searchable)
Uses Tesseract with full language models, which is too heavy for every browser tab.
Office ↔ PDF & PDF/A
Needs LibreOffice to render Word, Excel and PowerPoint files with the correct layout.
Protect / Unlock
Uses qpdf AES-256 encryption, which is not available client-side.
Repair
A deep rebuild of damaged PDF structures relies on the native qpdf engine.
Poster / tile & Compare
Pixel-accurate rendering of huge plans is much faster in the desktop app.
