How to use this tool
Compare Documents Instantly, In Your Browser
Our Document Compare tool highlights exactly what changed between two versions of a document - down to the word. Paste text directly or upload files, and get a clear, color-coded diff without ever uploading your files to a server.
What You Can Do
- Multiple Formats: Compare plain text, Markdown, PDF, and Word (.docx) documents.
- Side-by-Side or Unified View: Switch between a two-column comparison or a classic unified diff.
- Word-Level Highlighting: Changed lines show exactly which words were added or removed, not just that the line changed.
- Ignore Whitespace or Case: Filter out noisy formatting differences to focus on real content changes.
- Similarity Score: Instantly see how similar two documents are, with a full breakdown of additions, deletions, and modifications.
- Export Results: Copy the diff report or download it as a text file to share with others.
Everything runs locally using your browser's own processing power - your documents are never sent anywhere, making this ideal for contracts, essays, code, and any sensitive content.
