Text Diff Checker Online — Compare Two Texts

Compare two texts line by line and see added and removed lines. Optional ignore-whitespace. Neither side is stored.

How it works

Removed lines start with - and added lines start with +. JSON mode sorts keys before comparing.
No account is required. Very large texts are rejected instead of being compared without a limit.
Results update as you type. Your input is processed over HTTPS and is not stored or logged.
Input is limited to 128 KB per request.
