FAQ
Frequently asked questions
- How are differences detected?
- Each page is rendered and compared visually, so any change in text, images, or layout shows up as a highlighted region.
- What if the documents have different page counts?
- Pages are compared in order; pages that exist in only one document are flagged so you don’t miss them.
- Are my files uploaded?
- No. Both PDFs are rendered and compared entirely in your browser.
