Frequently asked questions
Is my text uploaded to a server?
No. Comparison runs entirely in your browser. Nothing is sent or stored on a server.
How does ignore whitespace work?
Leading and trailing spaces are trimmed and internal whitespace runs are collapsed before lines are compared. The original left-side text is still shown for matching lines.
What are the size limits?
Combined input is capped at 100,000 characters and each side at 5,000 lines so the comparison stays responsive.
