Frequently asked questions
How does Compare PDF work?
Upload an original and revised PDF, choose text, visual, or both comparison modes, then review changed pages side by side and download a PDF report.
Can I compare scanned PDFs?
Yes. Visual comparison detects pixel-level page differences in scans. Text changes require a text layer; use OCR PDF first when you need text comparison for image-only scans.
Can I compare different page counts?
Yes. Added and removed pages are identified and included in the summary and report.
Will formatting differences be detected?
Yes. Visual mode detects practical layout, graphics, image, and formatting differences by rendering only for comparison. Your source PDFs are not modified.
Are files deleted?
Yes. Inputs are removed after processing. The report is removed after download, cancellation, failure, timeout, or automatic expiry.
