Why Choose Aservus PDF Protection?
Designed for maximum security and ease of use
Secure Server Encryption
Your PDF is encrypted on our secure server using 128-bit AES — the same standard used by banks and governments. The file is deleted immediately after you download it.
Password-Based Access Control
Set a strong password that recipients must enter before they can open the document. The password strength meter helps you choose a password that is hard to brute-force.
Granular Permissions
Control exactly what recipients can do once they open the file. Independently restrict printing, text copying, and document modifications to match your security requirements.
Instant & Free
No account, no subscription, and no waiting. Upload your PDF, set your password, and the protected file is ready to download within seconds — completely free.
Frequently Asked Questions
Is it safe to upload my PDF?
Yes. Your file is transmitted over a secure encrypted connection, processed on our server, and immediately deleted after download. We never store, read, or share your documents, and your password is never logged or retained on our end.
What happens if I forget my password?
Because we do not store your password or the encrypted file, we are unable to recover it for you. We strongly recommend saving your password in a password manager before closing the page. There is no way to unlock the PDF without the original password.
Can I prevent people from printing my PDF?
Yes. Simply uncheck the Allow Printing option in the permissions section before clicking Protect PDF. Most compliant PDF readers — including Adobe Acrobat and Preview on Mac — will honour this restriction. You can also restrict text copying and document modifications independently.
Is this service free?
Yes. Aservus PDF protection is 100% free to use with no account required. You can protect as many PDF files as you need at no cost, with no daily limits or file quotas.
Does it work on mobile?
Yes. The tool works directly in the browser on iOS and Android without any app installation. Simply open the page on your mobile device, upload your PDF from your camera roll or Files app, and download the protected version.
