PDFGeek does the everyday PDF jobs on your own machine, with none of the limits the web tools impose.

Merge as many files as you like, split a document into single pages or fixed-size chunks, pull pages out or drop the ones you don't want, rotate sideways scans, reorder a document, stamp a watermark across it, and add or remove password protection with AES-128 encryption.

The online alternatives cap you and then ask for money: 25 files per merge, three tasks an hour, a subscription to unlock batch mode. PDFGeek has no caps to lift, because your documents never leave your computer in the first place.

Available as a per-user installer that needs no admin rights, or as a single portable executable you can run from a USB stick. No bundled offers, no telemetry, no account. 100% free, no Pro tier, free to use at home and at work.

Built on .NET 8 and Avalonia. Requires Windows 10 or later, 64-bit.
