About Compare PDFs
- What does Compare PDFs do?
- Add the original and the new version, and get a line-by-line list of what was added and what was removed. It compares wording only — exactly what you need to check whether a contract or policy was changed between drafts.
- Who is it for?
- Students handing in work, professionals sending contracts and reports, administrators preparing submissions, and anyone who has hit an email attachment limit. No technical knowledge is needed.
- Is it free?
- Yes. Compare PDFs is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.
- Is it safe to use with confidential files?
- Yes, and not because we promise to behave. Compare PDFs never sends your file anywhere — the work happens in your browser. There is no upload, so there is no copy of your document in our systems at any point.
- What file formats are supported?
- Input: PDF. Output: TXT.
- Are there any limits?
- Compares the wording only. Changes to images, signatures, fonts or layout are not detected.
