Frequently asked questions

Are my files uploaded to a server?

No. Your file is read by your browser with FileReader and processed locally by pdf-lib. It never leaves your device and nothing is stored on any server.

Is there a file size limit?

There is no fixed limit. Processing happens on your device, so the only ceiling is your device's available memory. Very large files use a background worker to keep the page responsive.

Do I need to sign up or pay?

No. Add margins is completely free with no signup, no watermark and no paywall. Download the result as many times as you like.

Does it work on mobile?

Yes. The tool is mobile-first and runs in any modern mobile browser. You can also install use2pdf as an app and use it offline.

Does it work offline?

Yes. Once the page has loaded, the tool is cached by the service worker, so Add margins keeps working with no internet connection.
