PDF to PNG

Draw each page as a PNG. Transparent areas stay transparent.

PDF rendering uses PDF.js (Apache-2.0). The worker stays on this site.

About this tool

PNG output is for pages that need a transparent background or a lossless raster — UI specs, stamps, overlays. Each page is drawn as a PNG; several pages zip.

This is still a photograph of the page, not a layered design file. Text becomes pixels. If you only need a small shareable picture, PDF to JPG is usually lighter.

PDF.js renders locally to a canvas that can keep clear pixels, then PNG encode. 50 MB. Encrypted inputs refused. Zip for more than one page.

How to convert PDF pages to PNG

  1. Choose a PDF. Pages are drawn as PNG in this tab.
  2. Convert. Transparent areas stay transparent where the page had no backdrop.
  3. Download a PNG or a zip.

50 MB. White page backgrounds stay white — they are not made transparent automatically. Not OCR.

FAQ

Does rasterizing pages to PNG leave this browser?
No. Rendering is local.
When is PNG better than JPEG?
Sharp UI, text, and any real transparency. Photographs of scans are often finer as JPEG.
Can I make the white background transparent?
Not automatically. This keeps what the page already had.
Why are PNGs large?
Lossless rasters of full pages are large. Resize image afterwards if you need fewer pixels.
Password PDF?
Unlock PDF first if you are allowed to open it.
