About this tool

Reviewing a new version of a contract, notice, or proposal by eye is slow and risky. Compare PDFs to see exactly which lines changed, so you can focus on what matters.

Frequently asked questions

What does it compare?

The text on each page, line by line. Visual changes (colors, images, exact positioning) won't show up. To compare those, convert the pages to images with PDF to JPG.

When should I compare the entire document?

Use this when an inserted paragraph has pushed the rest of the text onto later pages. Comparing page by page would make everything look different, but comparing the entire document shows only the insertion.

Does it work with scanned PDFs?

Only if the PDF contains text. For scanned documents, run each file through PDF OCR first.

Are my contracts uploaded to a server?

No. Your files are read and compared in your browser and never leave your device.

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your file is read and processed on your device, and not a single byte is sent over the internet. You can even disconnect from the internet after the page loads.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
