Frequently Asked Questions

What differences can be detected?
Currently we compare page count, file size, and overall structure. Visual page-by-page comparison requires Ghostscript and is shown when available.
Can it detect if text was changed?
Text-level comparison is being developed. Currently structural comparison (pages, size, metadata) is performed.
What if the files are identical?
The tool will report that the files appear identical based on structural comparison.
Can I compare password-protected PDFs?
You need to unlock both PDFs first using our Unlock PDF tool before comparing.
Is there a page limit for comparison?
No page limit. Large PDFs can be compared as long as each file is under 200 MB.
