Text Diff Checker — Frequently Asked Questions
Everything you need to know about using Text Diff Checker.
How does the comparison work?
The tool uses the Longest Common Subsequence algorithm to find the optimal alignment, then highlights additions and removals.
Can I compare code files?
Yes. The tool uses monospace font and preserves whitespace, making it suitable for code and config files.
Is there a text length limit?
No hard limit. Very large texts may take a moment to process since the diff algorithm runs in your browser.
