PDF protect / encrypt
Encrypt PDFs with a password, restrict printing and editing, and download a protected copy. Passwords are never stored — keep yours safe.
Drop a PDF here
Drop anywhere, or choose an option below.
Files stay private while we process them, then they are deleted. Nothing is published unless you choose to share a result later.
Passwords are never stored in the database, logs, or analytics.
AES-256 by default, with a broader-compatibility option when needed.
Pages, text, and images stay intact — only security settings change.
Encryption runs privately in the background.
How it works
Step 1
Add one document you want to password-protect.
Step 2
Choose a preset or customize printing, copying, and editing.
Step 3
We create an encrypted new PDF. Keep your password safe.
PDF protect
Require a password before anyone can view the PDF.
Restrict printing, copying, editing, annotations, and forms.
Standard, restricted editing, read-only, or custom.
Prefer AES-256, or choose RC4 for older readers.
We verify encryption and page integrity before download.
We cannot recover lost passwords — by design.
Formats & limits
Standard PDF files up to 50 MB.
AES-256 (recommended) or RC4 (compatible).
protected.pdf by default — original file unchanged.
Up to 500 pages per document.
Enforced by PDF readers — not a substitute for access control.
Passwords are ephemeral and never written to job history.
Questions
An open password is required before the PDF can be viewed. Optional permission restrictions can limit printing, copying, and editing in supporting readers.
Yes for modern security. Choose Compatible (RC4) only if you need older PDF software that does not support AES-256.
No. Keep a copy of your password. We never store it and cannot reset it.
No. They are enforced by PDF readers and encryption standards. Do not treat them as a replacement for controlling access to the original file.
