About this tool
Find every difference between two versions of a document, such as a contract or draft. You get a side-by-side report with changes marked, plus a count of the pages and words affected.
Common questions
What do the colors mean?
Red marks words that were removed, green marks words that were added, and amber marks visual changes such as a swapped picture.
Does it work on scanned documents?
Yes. Scans are compared visually, and the areas that differ are marked in amber.
Is it free to use?
Yes. You can use it without an account a few times a day, and a free account raises the daily limit. Nothing is added to your file unless you ask for it.
What happens to my files?
Your files are only used to run the tool you chose, and they're deleted automatically after about 24 hours.
Do I need to install anything?
No. It all works in your browser, on any computer or phone.
