Features

  • View text line by line, with changed lines and edits within each line highlighted. Edit and save directly in regular text comparisons.
  • Compare CSV and TSV as tables, and browse the structure of JSON, plist, XML, and YAML. PDF and RTF comparisons use extracted text.
  • Switch between side-by-side, overlay, and difference views for images. Inspect binary files in hexadecimal and compare the items inside ZIP archives.
  • Compare two folders and copy items that exist on only one side to the other.
  • Three-file comparisons are read-only. Table, structure, image, hexadecimal, and ZIP-content comparisons are also for viewing, without editing.
