Questions frequentes

How does PDF comparison work?

Upload two versions of a PDF, and the tool highlights the differences between them visually. Text changes, layout shifts, and image modifications are marked for easy review.

What types of differences can the tool detect?

The tool detects text changes, added or removed content, formatting shifts, and graphical differences between the two PDF versions.

Do both PDFs need to have the same number of pages?

Comparison works best when both documents have the same page count. Differing page counts may result in misaligned comparisons, so normalize the documents first if possible.

When is PDF comparison most useful?

It is useful for reviewing contract revisions, comparing document drafts, verifying changes in legal filings, and auditing document updates before approval.

Can I compare scanned PDFs?

Text-based PDFs produce the clearest comparisons. Scanned PDFs may show image-level differences rather than text-level changes. Run OCR on the documents first for better results.

Quand utiliser cet outil

Compare two versions of a PDF to see exactly what changed between them. Differences are highlighted visually so you can review text, layout, and image changes side by side.

  • Two contract versions need to be checked for text or formatting changes.
  • A revised document should be compared against the original before approval.
  • Audit and compliance reviews require a change-by-change record.

Conseils pour de meilleurs résultats

  • Ensure both PDFs have the same page count for the cleanest comparison.
  • Review highlighted differences carefully because layout shifts may also flag formatting changes.
  • Keep both original files until the comparison review is complete.

Confidentialité et rétention des fichiers

Both PDFs are temporarily loaded and compared. Uploaded files and comparison results are scheduled for deletion within the standard 30-minute retention window.
