How to password protect a PDF online
- Choose the PDF you want to lock.
- Enter the password you want people to need in order to open it.
- Optionally check "Prevent printing" and/or "Prevent copying" to restrict what's allowed once it's open.
- Click Protect PDF and download the password-protected copy.
Why use VitePDF
- Real AES-256 encryption — the file genuinely requires your password to open in any PDF reader afterward.
- Optional permission locks (no printing, no copying) enforced even for people who do have the password.
- No account required, no watermark added to your document.
Frequently asked questions
Will this work with any PDF reader, or only VitePDF?
Any standard PDF reader — Adobe Acrobat, Preview, browser PDF viewers, and so on. The password is a real part of the file's encryption, not something specific to this site.
Can I remove the password later?
Yes — use VitePDF's Unlock PDF tool with the same password to get back an unprotected copy.
Is my file safe when using this tool?
Your file and password are uploaded to a conversion server to process it, the same way any online PDF protection tool with real encryption works, and aren't retained after conversion.
