Frequently Asked Questions
How does the comparison work?+
The tool renders both PDFs side by side and highlights visual differences between them. This lets you quickly spot changes in text, images, and layout between two versions of a document.
Are my documents uploaded for comparison?+
No. Both PDFs are processed entirely in your browser. Neither document is ever sent to a server — your confidential drafts and contracts stay private.
Can I compare PDFs with different page counts?+
Yes. The tool handles PDFs with different numbers of pages. Extra pages in either document are shown separately.
