Free Text Diff Tool

Compare two texts and highlight differences with our free tool. Side-by-side, inline, and unified diff views available.

Frequently Asked Questions

What's the difference between diff views?

Side-by-side shows old and new text in parallel. Inline shows changes within the text flow. Unified diff uses the standard format from version control tools.

Can I ignore whitespace changes?

Yes! Enable whitespace ignore to focus on meaningful content changes. This is helpful when formatting changed but content didn't.

How do I compare large texts?

The tool handles large texts efficiently. For very long documents, the summary shows changed line counts. Scroll through the diff to see all changes.
