Protect PDF

What is PDF Protect?

PDF Protect adds a password to your PDF files using standard PDF encryption, so any PDF reader will ask for the password before opening the document. This tool runs entirely in your browser — your files and passwords are never uploaded.

How to Use This Tool

1. Upload a PDF file by clicking the upload area or dragging and dropping.
2. Enter a password (minimum 4 characters) and confirm it.
3. Choose permission settings: allow or restrict printing and text copying.
4. Click Protect PDF to process the file.
5. Download the protected PDF.

When to Use PDF Protect

• Share confidential reports or contracts with restricted access.
• Protect draft documents from being freely distributed.
• Add a layer of security before emailing sensitive PDFs.
• Restrict printing or copying of proprietary content.

Tips

• Use a strong password with letters, numbers, and symbols for better security.
• For maximum security (AES-256 encryption), use Adobe Acrobat or a similar desktop tool.
• Remember your password — there is no recovery option.
• The protected file is slightly larger than the original due to the protection header.
