Frequently Asked Questions — Compare PDFs
Everything you need to know about how to compare pdfs online
Does it compare images or layout?
No. It compares the extracted text of each page. Use PDF to JPG and compare images manually for visual checks.
Can I compare more than two files?
Compare them in pairs. The tool works on exactly two documents at a time.
Are my files secure while I compare PDFs?
Yes. Everything happens inside your browser using JavaScript and WebAssembly. Your file is never uploaded, and nothing is stored on a server.
Do you keep a copy of my document?
No. The file lives in your browser's memory only. When you close or refresh the tab it is gone. We cannot see it, and neither can anyone else.
