Online text comparison
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.
Quick start
Compare two versions side by side, ignore case or spacing differences, and highlight changed words. Open local text files and export the last comparison without uploading the contents.
