How does the Protect PDF tool work?
Our tool encrypts your PDF files using high-strength security algorithms. It allows you to add user passwords (required to open the document) or owner passwords (required to restrict permissions like printing, editing, or text copying).
This process guarantees that you retain high-fidelity formatting, including layout structures, embedded fonts, and graphics, while protecting your document with industry-standard security layers.
Privacy Architecture
Your privacy and document security are paramount. The uploaded files are transferred securely via standard 256-bit SSL encryption. Once the encryption process finishes, the resultant data and your original document are automatically marked for deletion from the active processing servers, ensuring your sensitive layouts, legal contracts, or personal files are safe.
Frequently Asked Questions
Are my PDF files uploaded to a server?
Yes. In order to compile security structures and encrypt document contents, the file is temporarily transferred via encrypted HTTPS to a dedicated processing array layer where protection is applied.
What level of security encryption is applied to my PDF?
We utilize industry-standard AES-256 encryption, ensuring that your restricted permissions and password keys remain highly secure.
Is there a size limit to the documents I can secure?
Currently, the tool supports single PDF files up to 25 Megabytes (MB) in size, which easily covers standard legal documents and statements.
Are my passwords or keys saved on your servers?
No! The security keys are applied instantly during the encrypted file output process and are never stored or logged on our servers.
Are my original PDF files permanently modified?
No. The internal engine strictly reads your source PDF file to output a separate secured download, leaving your original local file completely untouched.
