Frequently Asked Questions

Does it highlight text differences?
This is a visual comparison tool. It helps you spot layout changes, moved elements, and visual differences. For strict text diffing, you might need to extract text first.
Is it secure?
Yes. The comparison happens entirely in your browser (Client-side rendering). Your documents are not sent to any server for analysis.
Can I compare multi-page PDFs?
Yes. You can navigate through the pages using the toolbar controls. Both documents will turn pages simultaneously.
