Paste the original on one side and the changed version on the other. The differences appear side by side: removed lines on the left, added lines on the right, and changed lines paired up with the changed words highlighted. The summary counts added, removed and changed lines.
Options
Ignore whitespace treats runs of spaces and tabs as one and ignores them at line ends.
Ignore case treats upper and lower case as the same. Copy unified diff gives the
familiar -/+ format used by Git and code reviews.
Good to know
Is my text uploaded?
No. The comparison runs in your browser, so it's safe for contracts, configs and code.
Do Windows and Mac line endings count as changes?
No. Line endings are normalised before comparing.
