Free Online Diff Checker Compare Text & Code
TOOLBeans Diff Checker compares two versions of any text or code and highlights exactly what changed line by line. Added lines are shown in green, removed lines in red, and modified lines show inline word-level highlighting so you can see the precise words that changed within a line.
Choose between Split view (side-by-side like a code review), Unified view (single column like git diff output), or Summary view with change statistics and a visual distribution chart. Toggle Ignore Whitespace to skip formatting-only changes, and Ignore Case for case-insensitive comparison. The context lines control lets you hide unchanged sections to focus only on what matters.
Upload files directly supports .txt, .js, .ts, .html, .css, .json, .xml, .md, .py, .sql, .yaml and more. Export the full diff as a standard unified diff .txt file. All processing runs entirely in your browser no text is uploaded to any server.
