About this tool
About RTSoftwares
A free, no-signup diff checker. Paste two versions of a text, code, JSON or SQL and see what was added, removed or changed - side by side or in one unified view - with the exact words that changed highlighted inside each line.
Options let you ignore case, whitespace or blank lines, pretty-print JSON before comparing (with optional key sorting), hide the unchanged parts, jump between changes, and copy or download the result as a unified diff.
Everything runs in your browser. Nothing you paste is sent to a server.
Diff Checker is built and maintained by RTSoftwares. We build small, free, no-signup web tools that run entirely in your browser.
