Find out if two PDFs have exactly the same bytes. Show both SHA-256 hashes, sizes and the first differing byte offset.
Your files are read locally; they are never sent to URL-CUT.
Choose exactly two PDF files together (up to 40 MB each). We compare the bytes directly and report the first mismatch, even if file sizes match. No conversion is performed.
Compare exactly two PDFs byte by byte in your browser, inspect SHA-256 hashes, sizes and the first differing offset.
Review the downloaded result before relying on it for an important submission. Complex documents, scans, unusual fonts, and damaged files can behave differently from simple PDFs.
Compare exactly two PDFs byte by byte in your browser, inspect SHA-256 hashes, sizes and the first differing offset.
Keep the original file as your source of truth and treat the downloaded result as a new working copy. Review the new file before replacing or deleting the original.
