How to compare two texts

  1. Paste the original text on the left and the changed text on the right, or open two files.
  2. Choose to compare by lines, words or characters.
  3. Read the highlighted differences: green was added, red was removed.

Options

  • By lines, with the changed words inside each line highlighted.
  • By words or characters, for small edits in prose.
  • Ignore upper/lower case and extra spaces.
  • Long unchanged parts are folded, so you see only what matters.

常见问题

Can I compare Word or PDF files?

Copy their text in first (for PDFs, PDF to Text helps). Formatting is not compared, only text.

Is there a size limit?

Large texts work, but texts that are completely different are not compared in detail.
