Frequently asked questions
Is Compare Word Documents free?
Yes. There's no sign-up, no watermark and no usage limit.
Are my files uploaded to a server?
No. Compare Word Documents runs entirely in your browser. Your files never leave your device and nothing is stored — close the tab and everything is gone.
Which file types can I use?
DOCX, DOC, RTF, TXT. Files are checked by their actual content, not just the extension, so renamed or damaged files are caught early.
Is there a file size limit?
Each file can be up to 200.0 MB, and you can process up to 2 files at once. Because processing uses your device's memory, very large files work best on a computer.
Does it work on my phone?
Yes. It works in modern mobile browsers on Android and iPhone. Heavier jobs (large PDFs, OCR) are faster on a computer.
Are there any limitations?
Add the original first, then the new version.
