Why Protect a PDF?
PDF protection is commonly used when sending contracts, invoices, proposals, financial statements, legal files, and internal reports. Adding a password can help reduce accidental access and reinforce document handling expectations.
🔐 Better Access Control
Password protection adds a gate before the PDF can be opened or modified, which is useful in sensitive sharing workflows.
📄 Secure Distribution
Protected PDFs are common in client communication, HR handoffs, finance, and compliance-driven documentation.
How This Browser-Only Protect PDF Workflow Works
SwiftTools renders each page of the source PDF in your browser and rebuilds the document as a new password-protected PDF file with encryption options applied. This approach works without a backend service and keeps the file on the client side during processing.
Because the protected output is rebuilt from rendered pages, the final PDF preserves page appearance but not the original underlying editable PDF structure. That tradeoff is what makes browser-only password protection possible with the current frontend stack.
