Everything you do with PDFs
Read anything
Smooth even at 1000+ pages. Search, select and copy text, night mode for pages.
Annotate
Highlight, underline, pen, shapes, text and notes, with undo for everything.
Sign and fill in
Fill in PDF forms and place your signature — drawn, typed or from a picture.
Scan and tools
Scan paper with the camera, make it searchable with on-device OCR, protect, compress or repair PDFs.
Send to your devices
End-to-end encrypted transfer between your phones and tablets, with a QR code.
Never lose the original
Imports are copies and every save is a version you can go back to.
Private by design
No analytics, no crash reporting, no account and no server of ours. The network is used only while you transfer documents, and you can keep that to your own Wi‑Fi.
