All-in-one PDF program for Windows · Built on our own engine

Easy to read, easy to edit —
your PDF program

A compact toolbar with just the essentials, so anyone can view and edit right away. Convert PDFs to Word and PowerPoint with our in-house engine, recognize scanned text with the high-accuracy OCR pack, and protect files with passwords and signatures — conversion, editing and OCR all happen on your own PC, and your documents are never uploaded to a server.

Free Download (Windows · 315MB)

In the app installed from the App Store, Pro requires a separate in-app subscription under Apple's rules — PC licence keys do not apply. In the Android app your PC licence key works as is.
