Protect PDF

What is PDF Protect?

PDF Protect adds password-based access restriction to your PDF files. It obfuscates the file contents so the document cannot be casually opened or read without the correct password. 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.
