About Diffchecker

Diffchecker compares text, code, PDFs, Word documents, Excel spreadsheets, PowerPoints, and images. The free online tool runs in any browser with no sign-up and lets users save and share diffs online and leave line-by-line comments. Diffchecker Desktop runs fully offline on Windows, Mac, and Linux, so files never leave the device, making it a private, secure choice for redlining legal contracts and confidential documents. Plans start free, with Pro + Desktop from $15 per user per month.
