Protect PDF adds password encryption and permission restrictions (print, copy, edit) to a file, with separate open-password and owner-password options for controlling access versus editing rights.
Contracts, statements, HR files — anything that shouldn't be opened by the wrong person.
Anyone opening the file will need it. Use a passphrase of 12+ characters.
Add a separate permissions password and turn off printing, copying or editing.
Send the file and the password through different channels, like email and a phone message.
Four or more random words, or 12+ characters, is far harder to guess than a short password.
Email the file and share the password by phone or message — never in the same email.
A lost password can't be recovered — by us or anyone else. Save it in a password manager.
AES-256 is the strongest option. Choose AES-128 only if recipients use very old PDF readers.
Legal teams protect contracts with passwords before emailing to clients, preventing forwarding and unauthorized viewing.
Finance teams encrypt board-meeting PDFs with strong passwords, preventing leaks to unauthorized employees.
Healthcare staff protect patient PDFs with AES-256 for HIPAA compliance during transmission.
Yes — set an open password with printing/editing permissions turned off separately.
128-bit AES (default, compatible with Acrobat 7+) or 256-bit AES (maximum security, compatible with Acrobat 9+). Choose 256-bit for sensitive data.
User password: required to open the PDF. Owner password: required to change permissions (print, copy, edit). Set both for full control.
Printing (allow/deny, low-quality vs high-quality), copying text/images, editing content, form filling, signing, page extraction, and accessibility/screen-reader.
No. Strong encryption (AES-128 or AES-256) is computationally infeasible to crack. Store passwords in a password manager. We cannot recover lost passwords.
AES-128 works in Adobe Acrobat 7+ and most readers. AES-256 needs Acrobat 9+ or modern readers (Chrome, Firefox, Edge built-in viewers all support it).
12+ characters with mixed letters, numbers, and symbols. The protect PDF tool warns on weak passwords (under 8 chars or dictionary words).
Yes — 30 protect operations per day for guests, more on free accounts. No watermark on output.
No. Passwords are used in-memory for encryption and immediately discarded. We never log or store passwords.
