PDFGeek: Free PDF Tools for Chrome, Edge and Firefox That Never Upload Your Files

In September 2026, a Chrome extension called Password Protect PDF was one of 19 pulled from the store for secretly stealing data. A few years earlier, PDF Toolbox, with close to 2 million users, was caught loading hidden code onto every page its users visited. Free PDF tools have a habit of wanting more than your PDF.

So we built PDFGeek. It merges, splits, rotates and password protects PDFs, and turns pictures into PDFs, all inside a tab of your browser. Your files never leave your computer. It’s free, open source and has no tracking at all.

Quick Facts

• Free. No Pro tier, no ads and no limit.
• Open source under the GPL-3.0, with the full source on GitHub.
• Works in Chrome, Edge, Brave, Opera, Vivaldi and Firefox.
• No account and nothing sent anywhere.

What it does

• Merge: drag several PDFs into order and merge them into one file.
• Split: every page as its own file, page ranges, or a new file every few pages.
• Organise pages: reorder, rotate and remove pages with a preview of each one.
• Pictures to PDF: JPG, PNG and WebP onto A4, Letter or a page that fits.
• Passwords: add AES-256 protection, or remove a password you know.
• Shrink: make a PDF smaller without losing any quality.

How it works

PDFGeek bundles well-known open-source PDF libraries (pdf-lib, Mozilla’s PDF.js and qpdf) and runs them inside your browser. There is no server to send your files to, and in our tests the only request PDFGeek ever made was to download a PDF link you chose to open in it. If you prefer a desktop app, there is also PDFGeek for Windows.

How to install it

Store listings for Edge and Firefox are on the way. Until then, adding it yourself takes about a minute:

1. Download the ZIP and unzip it somewhere you’ll keep it.
2. Go to chrome://extensions (or edge://extensions) and switch on Developer mode.
3. Click Load unpacked and pick the pdfgeek folder.

On Firefox, grab the Firefox version instead and load it from about:debugging. The PDFGeek page walks through every step with screenshots.
