PDF

Strong encryption, done on your device

Localvert encrypts the PDF with AES-256, the strongest standard PDF encryption. Anyone who opens the file must type the password, in any PDF reader — Acrobat, Chrome, Preview or a phone.

Because the encryption happens in your browser, the unprotected document and your password are never uploaded — which is the whole point of protecting it.

Choose a good password

Use a long password you don't use elsewhere, and send it through a different channel than the file — for example, email the PDF and text the password.

Frequently asked questions

What if I forget the password?

It can't be recovered — not by Localvert or anyone else. Keep the original file, or store the password somewhere safe.

Can I remove the password later?

Yes. Open Unlock PDF and enter the password to save a copy without it.

Is my document uploaded?

No. The PDF is encrypted inside your browser.
