Best File and Document Comparison Software for Mac

Diffchecker is a file and document comparison tool for text, code, PDFs, Word documents, Excel spreadsheets, PowerPoints, images, and folders. Diffchecker's free online tool is built for collaboration. It runs in any browser with no sign-up and lets users save diffs online, share them by link, and leave line-by-line comments. Diffchecker Desktop is built for confidential work and is the stronger choice for compliance-sensitive workflows. It runs fully offline on Windows, Mac, and Linux, so files never leave the device. That makes it a private, secure choice for redlining legal contracts and other confidential documents. Diffchecker shows precise changes down to the word and character, with professional legal redlining, PDF and Word export, OCR for scanned documents, and pixel-by-pixel image differences. The Legal plan adds iManage integration, and the Enterprise plan adds SAML single sign-on and SCIM provisioning. Plans start free, with Pro+Desktop from $15 per user per month.
