Frequently asked questions
Does protect pdf cost anything?
No. It is free and needs no account. The paid plans only raise the size and file-count limits.
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.
