Frequently Asked Questions
What's the difference between user and owner passwords?
A user password is required to open and view the PDF document. An owner password allows changing security settings and permissions. You can set one or both types depending on your security needs.
Are my files uploaded to your servers?
No, all PDF protection is performed entirely in your browser using client-side JavaScript. Your files never leave your device, ensuring complete privacy and security.
What file size limits apply?
The tool supports PDF files up to 50MB in size. Larger files may take longer to process or cause memory issues in your browser.
Can I remove password protection later?
To remove password protection, you'll need the original password and appropriate PDF editing software. Our tool currently only adds protection, not removes it.
Why Encrypting Your PDFs is Crucial
In the digital age, protecting sensitive information is more important than ever. PDF files often contain confidential data, such as financial reports, legal contracts, personal identification, or unpublished manuscripts. Leaving these documents unprotected can expose you to significant risks, including data theft, unauthorized distribution, and intellectual property infringement.
Our PDF Protection tool provides a robust, first line of defense. By adding a password, you ensure that only authorized individuals can access the content. Furthermore, by setting an owner password and configuring permissions, you can control exactly how others interact with your document—preventing unauthorized printing, copying of text, or modifications. This granular control is essential for maintaining document integrity and security.
