Text Diff

About this tool

What does the text diff tool show?

A character-level and line-level diff of two text inputs, with additions highlighted in green, deletions in red, and unchanged lines in neutral. Toggle between inline and side-by-side views.

Is it useful for comparing document versions?

Yes. Paste the old version on the left and the new version on the right to see exactly what changed.

Does it ignore whitespace differences?

Toggle 'Ignore whitespace' to skip differences that are only indentation or trailing spaces.

Can I download the diff?

Yes. Export as a unified diff (.diff) file or copy the highlighted output as HTML.
