Online Text Diff Tool

Compare two texts and see exactly what changed, line by line.

Paste two versions of a document, code snippet, or any text and instantly see what changed. Added lines are highlighted in green, removed lines in red — just like a git diff, but in your browser with no setup.

Why This Diff Tool Stands Out

Color-Coded Changes
Green for additions, red for deletions — changes are unmissable.
Line-by-Line View
See exactly which lines were added, removed, or modified.
Client-Side Only
Your text is never uploaded — comparison runs entirely in the browser.
No Registration
Open and compare — no account, no waiting.

How to Compare Two Texts

  1. Paste the original text in the left panel.
  2. Paste the modified text in the right panel.
  3. The differences are highlighted automatically below.

FAQ

Can I compare code files?

Yes, paste any plain text including source code, configs, or prose.

Does it work for large documents?

Yes, performance depends on your browser but most modern browsers handle thousands of lines comfortably.

Can I download the diff?

You can copy the diff output and paste it wherever you need it.

Great For
