Privacy & limits

Most tools process content entirely in your browser. A few formats have clear boundaries:

  • Text, JSON, CSV, lists, HTML, CSS, SQL, and similar formats never upload to our servers.
  • PDF compare uses the extracted text layer—not a full visual redline of layout or scans.
  • Image compare highlights pixels; mismatched sizes and compression can create noise.
