Practical Use Cases

Confidential drafts

Add access control before sending an internal review document.

Personal records

Protect statements or records stored in a shared location.

Privacy and File Processing

Browser-local processing

Protect PDF keeps its PDF input in browser memory while the operation runs. The workflow creates Password-protected PDF for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.

Supported Inputs and Outputs

Input

  • PDF

Output

  • Password-protected PDF

How It Works

The local qpdf WebAssembly engine rewrites the document with the chosen PDF encryption and permissions using the password supplied for this operation.

Limitations and Important Notes

  • A forgotten password cannot be recovered by GXA Toolbox.
  • Protection permissions are not a substitute for secure delivery or storage.
  • Existing signatures and advanced security settings may not survive rewriting.

Worked Example

Protect a financial statement with a unique passphrase, download it, and confirm it prompts for that passphrase before distribution.

Helpful Tips

  • Share the password through a different channel from the file.
  • Keep an unencrypted original in an appropriately secured location.

Frequently Asked Questions

What encryption engine is used?

The browser workflow uses the bundled qpdf WebAssembly engine.

Can GXA Toolbox recover my password?

No. Store the password safely before protecting the file.

Does a password prevent screenshots?

No. It controls PDF access but cannot prevent an authorized viewer from capturing content.
