Diff — compare two files

Side-by-side or unified, like VisualDiffer or Kaleidoscope: changed lines, and the exact words that changed inside them. Drop two files at once (the older one goes left), drop one on a side, or paste text. Files never leave your browser; binary files are compared by size and SHA-256.
