File Diff

Compare two files and highlight differences

About File Diff

Compare two files side-by-side and highlight every difference — supports text and binary files, all processed in your browser.

How to use File Diff

  1. 1Drop or select File A (the original) and File B (the modified version).
  2. 2Click Compare to generate the diff.
  3. 3Review the highlighted differences: green for added lines, red for removed lines.
  4. 4Switch between Split (side-by-side) and Unified views depending on your preference.
  5. 5Enable character-level diff for a more granular view of changes within lines.
  6. 6Copy the diff or download a .diff file for sharing with your team.

Tips

  • Use the unified view for quick scanning and split view for detailed line-by-line comparison.
  • Character-level diff is especially useful for spotting typos or small changes in configuration files.
  • Binary mode shows a hex dump for non-text files — useful for verifying file integrity.
