About this tool

PNG is the pick when quality matters more than size. Fine line art, diagrams with hard edges, screenshot-grade exports for documentation, anything you plan to crop or edit again later. PNG is lossless, so text comes out sharp without the soft halo JPG compression leaves around dark type.

Every page renders at a high-DPI scale. One page downloads as a single .png; more pages arrive zipped, numbered, and zero-padded so they sort in order. Transparency survives too. A page drawn on a transparent background keeps its alpha channel instead of being flattened onto white.

pdf.js renders each page to a canvas and the browser writes the PNG itself. Nothing uploads and nothing is logged. If smaller files matter more than perfectly crisp edges, the PDF to JPG tool is the same flow with JPEG output.

Frequently asked questions

Why choose PNG over JPG?
PNG is lossless and keeps transparency, so text edges and thin lines stay perfectly crisp. JPG files are much smaller but show artifacts around sharp edges. Diagrams, screenshots, and archival want PNG. Photo-heavy pages where size matters want JPG.
Does the PNG keep transparency?
Yes. A transparent page background exports with its alpha channel intact rather than being flattened onto a white rectangle. Solid backgrounds just come out opaque, as you'd expect.
What resolution are the images?
Pages render at 2× their native PDF size, roughly 144 DPI. Sharp on high-density screens, decent in print at original size.
What do I get for a multi-page PDF?
A .zip with one PNG per page, numbered like `mydoc-page-01.png` so everything sorts in order. A single-page PDF skips the zip and downloads as one .png.
Is my PDF uploaded anywhere?
No. Rendering and encoding both happen in your browser with pdf.js. Watch the network panel while it converts and you'll see no request carries your file.
