About the Social Security card
Your Social Security card shows your name and Social Security number. Employers and some agencies ask for a copy, but the number is valuable to identity thieves – share copies carefully.
Issued by the Social Security Administration. Commonly needed for new job paperwork, name changes, some benefit applications.
Frequently asked questions
Will the other person be able to open it?
Yes – any PDF app (Adobe Reader, Preview, Chrome, phone viewers) asks for the password and opens it.
Is my file uploaded?
No. The file opens inside your browser and never leaves your phone or computer – there's no upload, no account and nothing for us to store. That's why it's safe for tax forms, ID and bank documents.
Which encryption does Protect PDF use?
AES-256, the strongest encryption the PDF format offers. Adobe Acrobat Reader, Chrome and the PDF viewers on Android and iPhone open it once the password is typed.
What is the difference between a user password and an owner password?
The user password is what people type to open the file, and that is the one you set here. The owner password controls permissions; we set a random one that nobody sees, so the restrictions cannot be lifted with a guessed owner password.
Can I stop people from printing my PDF?
Yes. Turn off 'Allow printing' and PDF readers that follow the rules will block printing. Editing and changing pages are always blocked, while copying text stays allowed.
Can someone break the password on my PDF?
AES-256 itself cannot practically be broken, so the real risk is a password that is easy to guess. Use something long, like three words and a number, rather than a name or birth date.
Can you recover my PDF password if I lose it?
No. The password is not stored anywhere, so it cannot be recovered. Keep your original unlocked file, or note the password somewhere safe.
How should I share the password with the person receiving the file?
Send it separately from the file, for example the PDF by email and the password by SMS or a call. Then someone who gets one does not automatically get both.
Can I change the password on a PDF that is already locked?
Yes. Enter the current password first, then set a new one of at least 4 characters. The downloaded file opens only with the new password.
Is it free? Do I need to sign up?
It is completely free, with no sign-up, no watermark and no daily limit.
