By using this tool, you agree to our Terms and Privacy Policy.
- Add your file(s) above.
- Compare PDF runs instantly in your browser. Nothing leaves your device.
- Download the result. That's it.
Don't take our word for it. Open your browser's DevTools (F12), click the Network tab, and run the tool. It stays empty, because the code that processes your file shipped to your browser along with this page — there's no server for it to travel to.
- Does this compare layout or images too?
- No, only the extracted text content, page by page. It is built for catching wording and content changes between two drafts, not visual differences like moved images or reformatted layout.
- What about scanned PDFs with no selectable text?
- A page with no extractable text compares as blank, and the tool tells you which pages that happened on rather than pretending they matched.
- Are my files uploaded to a server?
- No. Everything runs locally in your browser. You can verify it yourself: open DevTools and watch the Network tab while the tool runs. It stays empty the whole time. This also means the tools keep working offline once the page has loaded.
- What are the free limits?
- Free covers every tool at full quality with no watermark and no signup: single jobs, up to 3 files and 25 MB total. Pro adds batch queues (up to 50 files), jobs up to 200 MB, tool chains and saved presets, all from one license that also unlocks the browser extension.
