How the Diff Checker Works
Paste two texts into the left and right panels, then click Compare. The tool splits both texts by newlines and compares line by line. Added lines (present only on the right) are shown in green. Removed lines (present only on the left) are shown in red. Modified lines (different content) are shown in yellow. Unchanged lines appear with no background.
Use Cases
Compare code snippets, config files, or documents before and after changes. Useful for code reviews, debugging, and document versioning. All comparison runs in your browser—nothing is uploaded.
