Frequently asked questions
How secure is it?
The file is encrypted with AES-256, the strongest method PDF knows. How secure it is depends mostly on the password: long and hard to guess is good.
Do you store my password?
Only briefly. The password is sent to our server for this one operation only, held for 10 minutes at most, deleted as soon as the operation ends, and never stored in a database or a log. That is also why we cannot recover a forgotten password.
What do the permissions do?
You can lock printing, copying and changes. PDF programs respect them, but they protect less than the password to open. With a separate password for the permissions they can be lifted later.
Why a server?
The encryption is done by a proven tool on our servers in the EU. The files are deleted after 60 minutes, with “Delete now” at once.
What does it cost?
Browser tools are free. Server tools include, for the launch, 50 operations a week without an account, up to 10 of them AI requests. File-size, concurrency and abuse-prevention limits still apply. Additional allowance cannot be purchased at launch. An operation that started on the server and then fails counts towards the free operations; one that never started does not.
Can the recipient open the file without extra software?
Yes. Adobe Acrobat Reader, Preview on the Mac and the common browsers ask for the password when opening it.
Do I need an account?
No. Protecting works without signing in, for PDFs up to 100 MB, and counts as one operation from your free allowance.

How the handover works →When “Protect PDF” helps
A payslip by email, a contract with personal data, papers for the tax adviser: with a password, only people who know it can open the file. Share the password another way than the file, such as by phone or message.
Password and permissions
The password to open encrypts all the content. You can also decide whether the file may be printed, copied or changed. These permissions apply once the file is open.
Removing the password again
If you know the password, remove it with “Unlock PDF” – then the file can be edited in every tool again.
