Frequently Asked Questions

How does the line-by-line diff comparison work?

The diff engine compares two text files or code snippets line by line, highlighting added lines in green (+), removed lines in red (-), and unchanged lines in neutral gray with precise line numbering.

Can I swap the original and modified texts quickly?

Yes, click the "Swap" button above the text panes to instantly exchange File A and File B to review inverse differences without copying and pasting manually.

Is confidential code or text safe when using this diff tool?

Yes. Everything executes strictly client-side inside your browser with zero network requests, making it completely safe for proprietary source code, secrets, and private documents.
