Conversion Mechanics
Saving a web page, report, or generated document as a PDF usually means sending it to a server to render. This renders the HTML file directly in your browser and captures it as a paginated PDF, so nothing about the page's content ever leaves your device. Works well for print-style documents, invoices, and reports; a page relying heavily on JavaScript to build its content after load may render differently than in a full browser tab, since only the HTML file's own markup and styles are captured.
Why It's Private
- Runs Entirely In Your Browser: Files are decoded and re-encoded strictly in local memory.
- No Network Requests: The converter makes no calls to any server. Check your browser's DevTools Network tab to confirm.
- Nothing to Sign Up For: No account, no upload, and no server-side storage of your files.
- Runs On Your Hardware: Processing uses your own device's CPU via Web Workers, not a remote server.
