How does the rendering happen in the browser?

We use pdf.js (Mozilla's PDF renderer) to draw each page onto a canvas, then export the canvas to your chosen format. The PDF never reaches a server.

Why pick PNG over JPG?

PNG is lossless — better for diagrams, screenshots, or anything you may need to OCR later. JPG is smaller for photographic content.

150 for screen viewing, 300 for printing. Anything beyond 300 rarely adds visible detail to a typical PDF.

Files never leave your device
