PDF to PNG Converter

Step 1 / 4 PDF to PNG

PNG is the go-to format when you need PDF pages as images without losing sharpness on text, diagrams or UI screenshots. Each page is rasterized to a lossless PNG at your chosen DPI, with optional transparency for pages that have no background fill. You can grab a single page or download every page bundled as a ZIP.

How to convert PDF to PNG

  1. 1

    Upload the PDF

    Any standard PDF. Scanned or text-based, both render fine.

  2. 2

    Choose DPI

    72 for web use, 150 for Retina-quality previews, 300 for print-detail output.

  3. 3

    Transparent background?

    Turn it on if pages have no fill and you want the page edges to be transparent.

  4. 4

    Download

    Individual PNGs per page, or a ZIP with `page-01.png`, `page-02.png`, and so on.

PNG vs JPG for PDF pages

Content type Better format Why
Text, tables, UI, diagrams PNG Lossless, keeps sharp edges
Photos, gradient-heavy art JPG Smaller files at equal visual quality
Needs transparency PNG JPG has no alpha channel
Chat attachment preview JPG Smaller, fine for casual viewing

DPI reference for A4 pages

  • 72 DPI -> 595 x 842 px. Matches typical blog/article embed sizes.
  • 96 DPI -> 794 x 1123 px. Default Windows rendering resolution.
  • 150 DPI -> 1240 x 1754 px. Sharp on Retina displays.
  • 300 DPI -> 2480 x 3508 px. Print-quality.

Practical tips

  • Compress afterwards. Lossless PNGs from a 300 DPI render can be huge. Run them through a PNG compressor (oxipng, pngcrush, or the image compression tool on this site) to cut 30-60% without changing pixels.
  • Split per page. If you only need the cover, convert just page 1 - saves bandwidth and time.
  • Transparency gotchas. PDFs with a white-filled rectangle behind the content will not look transparent even with the option on. The tool respects whatever the PDF says is there.

When to use this instead of a screenshot

Cropping and resizing screenshots of a PDF viewer introduces JPEG-like artefacts and imprecise sizing. Rendering directly from the PDF gives pixel-exact output at whatever DPI you choose.

Frequently Asked Questions

A 10-page text-heavy PDF at 150 DPI typically produces around 3-10 MB of PNGs. Full-page photographs can push each page over 2 MB. For smaller files, consider JPG or run the output through a PNG compressor.

Only if you pick a high enough DPI at render time. PNG is a raster format, so zooming in later cannot add detail. Render at 300 DPI or higher if you plan to zoom.

Yes. Enter a page number or range in the selector before converting and only those pages are rendered.

No. Your upload and the produced PNGs are stored on a temporary worker until the download completes, then both are deleted.
