Frequently Asked Questions

How does the diff checker work? +
The tool compares your two texts line by line. Lines only in the first text are shown in red (removed), lines only in the second text are shown in green (added), and matching lines are shown in grey (unchanged).
Can I compare code files? +
Yes. Paste any code, configuration files, JSON, SQL, or plain text. The tool highlights exactly which lines changed.
What does "ignore whitespace" do? +
When enabled, lines that differ only in leading/trailing spaces or tabs are treated as equal. Useful when comparing code that was reformatted.
Is there a size limit? +
There is no hard limit, but very large texts (100,000+ lines) may be slow since all processing happens in your browser.
Is my text sent to a server? +
No. The entire comparison is done in JavaScript in your browser. Your text never leaves your device.
