How It Works

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.

Frequently Asked Questions on Secure HTML to PDF Conversion

No. The page is captured as an image and placed into the PDF, the same approach most browser-only HTML-to-PDF tools use. This keeps everything private and client-side, but the output isn't a searchable text layer.
Yes. Content taller than a single A4 page is automatically split across as many pages as needed.
Anything referencing an external URL is fetched by your own browser while rendering, the same as opening the file directly would do. For a fully self-contained conversion, use an HTML file with embedded (base64) images.
