Frequently asked questions
Does compare pdf cost anything?
This tool is part of a paid plan. The Pricing page has the details.
Are my files kept on the server?
No. Files exist only long enough to be processed and are deleted automatically after 2 hours. You can also delete them yourself right after downloading the result.
Is there a file size limit?
Yes. Each tool has its own limit depending on your plan, shown just under the file picker. Paid plans raise it to 4 GB per file.
Can I use this on my phone?
Yes. PDFly runs entirely in the browser and the interface adapts to the screen, so it works on phones and tablets too.
