Frequently asked questions
What types of differences does the tool detect?+
The tool detects text additions, deletions, and modifications, as well as changes in images, layout shifts, and formatting differences between the two documents.
Can I compare PDFs with different page counts?+
Yes. The tool aligns pages based on content similarity and flags pages that exist in one document but not the other. Each page pair is compared independently.
Are my files kept private?+
Files are processed on our secure servers and deleted immediately after comparison is complete. They are never stored, shared, or accessed by anyone.
Does comparing PDFs require a subscription?+
Yes. PDF comparison is a Pro feature that uses server-side processing. It requires credits or an active subscription to use.
Can I export the comparison results?+
Yes. You can download a summary report highlighting all detected differences, making it easy to share findings with colleagues or keep a record of document changes.
