Differences
Paste or open two texts to compare them.
Frequently asked questions
- Is my text uploaded anywhere?
- No. Both texts are compared by your browser, on your device. Nothing you paste or open is sent to a server, so it's safe for code, contracts, and private documents.
- Is there a size limit?
- Files up to 50 MB each. Tens of thousands of lines compare in about a second; very large, very different files show the changed part as one block.
- Can I ignore whitespace or case?
- Yes. Turn on Ignore case, Ignore whitespace (spaces at the ends of lines and the amount of spacing), or Ignore blank lines. Ignored differences still show, but aren't marked as changes.
- Can I compare PDF or Word files?
- Yes. Drop a PDF or .docx file on either side and its text is extracted on your device. Formatting such as fonts and colors isn't compared, and scanned PDFs (images of text) have no text to compare.
- Can I save or share the result?
- Download it as a .diff patch file (works with git and patch), copy the patch, or print the comparison or save it as a PDF. There are no share links, because that would mean storing your text on a server.
- Is it really free?
- Yes. No account, no daily limit, and no paid version. Every feature is free.
