Comparing extracted PDF text

Upload two PDFs to receive a Markdown unified-diff report of their extracted text, including page boundaries.

Output behavior and limits

This is not a pixel comparison. Images, colors and layout can change without a text difference; scanned pages have no OCR comparison here.

Compare two revisions with one changed sentence. Review the diff alongside the PDFs when diagrams, signatures or scan quality matter.

Before replacing your original

  • This operation uploads to the processing server. Clear results after downloading; deletion requests can fail and scheduled cleanup depends on the server running.
