Compare2Word is a free online tool that lets you compare two DOCX documents in your browser and see added, removed, and rewritten text marked side by side

Compare2Word is a free, independent browser-based tool for comparing Word document text. Upload two DOCX files and the tool highlights added, removed, and rewritten wording in paragraphs, lists, and tables. You can view results in split view with both versions side by side, or unified view with all changes in one document.
All processing happens in your browser—files are never uploaded to a server. The tool works on Windows, macOS, Linux, and ChromeOS with any modern web browser. It does not compare fonts, page layout, images, or Word revision history.
Compare2Word handles files up to 50 MB and is designed for comparing contracts, reports, academic drafts, and other documents that go through multiple revisions. It requires no account creation, software installation, or Microsoft Word subscription.
