Render PDF pages as lossless PNGs

What is PDF to PNG Converter?

The same page rasteriser as the JPG converter, writing PNG instead. That format choice changes two things in practice. PNG is lossless, so line art, small type and flat-colour diagrams come out without the compression artefacts a JPG introduces, and PNG keeps an alpha channel, so the tool deliberately does not fill the canvas with a background colour — a page with transparency stays transparent instead of gaining a white or black rectangle. Resolution runs from 1× to 4×, the same 72 to 288 DPI presets. Multi-page documents come down as a ZIP with sequential filenames; a one-page PDF downloads straight away. Nothing is uploaded: the PDF is read into memory in the page and rendered by PDF.js inside the browser.

Turn PDF pages into sharp, lossless PNG images at the resolution you choose. Perfect for slides, diagrams and document thumbnails — 100% local processing.

Step-by-Step

How to use PDF to PNG Converter

1

Choose a PDF from your machine or drag one onto the drop area.

2

Pick a rendering scale — 1× through 4×, from 72 to 288 DPI.

3

Wait while PDF.js rasterises each page onto a canvas and encodes it as PNG.

4

Click a thumbnail for a single page, or download every page together as a ZIP.

Key Capabilities
  • Lossless PNG encoding preserves thin lines, small type and flat colour areas that JPEG smoothing damages.
  • No background fill is applied, so pages with transparency keep an alpha channel rather than acquiring a solid rectangle.
  • Identical four-step resolution control to the JPG renderer, from 72 DPI up to 288 DPI.
  • Every rendered page is retained as a blob, so one document can be downloaded whole or a page at a time without re-rendering.
Common Use Cases
  • A technical writer exports diagrams and charts from a PDF as PNG so they stay sharp when embedded in documentation.
  • A designer prepares lossless page images for a slide deck where JPG artefacts around thin lines would show.
  • A developer generates page thumbnails for an application that caches images rather than PDF bytes.

Frequently Asked Questions

Why use PNG rather than JPG for a page of text?
PNG is lossless. Text edges stay crisp because nothing is thrown away to save space, which matters most at the higher resolution settings where you are trying to capture fine detail.
Will a transparent PDF page stay transparent?
Yes. Unlike the JPG converter, this one leaves the canvas unpainted, so alpha survives into the PNG.
How big are the resulting files?
Larger than JPGs, and much larger at 3× and 4× where the pixel count is several times higher. A ZIP of many high-resolution pages will be correspondingly heavy.
Does this extract text instead of images?
No. This rasterises pages to pictures. If you want the selectable text layer, use the PDF to text extractor.
