A free, self-contained PDF toolkit for Windows — merge, split, rotate, watermark and protect PDFs without uploading a thing.
Download · Features · Screenshots · Build from source · License
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, images included, split a document into pages or fixed-size chunks, pull pages out or drop them, rotate sideways scans, reorder a document, stamp a watermark across it, and add or remove password protection.
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.
No installer bloat, no bundled offers, no telemetry. 100% free, no Pro tier, no upsells.
A full tour of every tool, in under a minute.
| What it is | Get it |
|---|---|
| Installer (recommended) — Start menu entry, desktop shortcut, clean uninstall | PDFGeekSetup.exe |
Portable — a single .exe, nothing installed, runs from a USB stick |
PDFGeek.exe |
The installer needs no admin rights and shows no UAC prompt — it installs for the current user by default. It bundles nothing, changes no file associations unless you tick the box, and uninstalls cleanly from Settings → Apps.
Prefer the portable build if you want to run it from a memory stick or leave no trace on the machine. Either way it is the same application.
Windows will warn you the first time you run it. PDFGeek isn't code-signed, because a certificate costs money we'd rather not put behind a free tool. Click More info → Run anyway. Every release publishes SHA256 checksums for both files so you can verify what you downloaded, and the source is right here so you can see exactly what it does.

- 🔗 Merge any number of PDFs and images into one, in the order you set — drag them in, reorder, done. JPG, PNG and WebP go in alongside the PDFs, either keeping their own size or forced to A4 or Letter.
- ✂️ Split a document into one file per page, or into fixed-size chunks.
- 📄 Extract or remove pages using print-dialog page ranges (
1-3, 5, 9-). - 🔄 Rotate sideways scans by 90°, 180° or 270°, on selected pages or the whole document.
- 🔀 Reorder a document by listing the pages in the order you want them.
- 💧 Watermark every page with your own text, at whatever size, opacity and angle you like.
- 🔐 Add a password with AES-128 encryption, with control over printing and copying.
- 🔓 Remove a password from a document you can already open.
- 🔒 Private — your documents are processed locally and never uploaded, with no telemetry and no account.
Clicking Check for updates makes a single request to GitHub's public releases API to compare version numbers. It sends no identifiers, no file names and no usage data, and it never downloads or installs anything on its own — if there's a newer version it just offers to open the page. Don't press it and PDFGeek makes no network connection at all.
Requires the .NET 8 SDK.
