Use this tool to compare two text fragments, source code snippets, configuration files, logs or translated copy. The diff is calculated locally in the browser and shown with line numbers and clear change colors.
Switch between side-by-side and unified views, hide unchanged lines, ignore letter case or whitespace noise, then copy the generated diff when you need to share the result.
✓Compare original and edited text without uploading it to the server.
✓Use side-by-side view for review and unified view for compact patch-style output.
✓Ignore case or whitespace when formatting noise is not important.
✓Copy the generated diff for comments, tickets and quick reviews.
✓Line numbers make it easier to find the changed fragment in the source document.
✓The comparison runs in your browser and does not require registration.
