Answers to common questions about using these PDF tools.

Page: https://pannapdf.app/help/

## Is it really free?

Yes. Every tool on this website is free, with no limit on how many files you do and no sign-up.

## Are my files sent anywhere?

No. The work is done by your own phone or computer, inside this page. Your files are never uploaded, so we never see them.

## Does it work without the internet?

After your first visit, yes, for the everyday tools. Two tools fetch a large extra part the first time you use them (locking with a password, and reading scans), so use those once while you are online.

## Where does my finished file go?

When you press Save, your browser saves it where it saves all downloads, usually a folder called Downloads.

## It says my PDF is locked.

The PDF has a password. Open "Remove a password", type the password, and save an unlocked copy. Then use that copy.

## It says my file is too large.

A web page only has so much memory. Files over about 300 MB are too big for it. The computer app will handle them.

## A tool I need is not here.

Some jobs cannot be done inside a web page. They are listed under "Only in the computer app". You can ask to be told when the app is ready.

## Can I use it on my phone?

Yes. Every tool works on a phone. Drawing and signing are easier on a bigger screen.
