PDF to PNG Converter

PNG is the right image format for PDF pages full of text, tables, charts and line drawings: it is lossless, so letters stay razor-sharp with none of the blurry halo JPEG leaves behind. This converter renders the pages you pick at 72, 150 or 300 DPI and can leave the page background transparent. It works entirely in your browser, so the PDF is never uploaded.

How to use this tool

1. Choose one or more PDF files.
2. Pick a resolution — 150 DPI for screens and documents, 300 DPI for print or zooming.
3. Tick “Transparent background” if you want only the printed content, for example a logo or a signature.
4. Optionally enter the pages to convert, then download the PNGs one by one or as a ZIP.

Formula

Image width (px) = page width (pt) ÷ 72 × DPI; image height (px) = page height (pt) ÷ 72 × DPI.

One PDF point is 1/72 inch. PNG files are usually several times larger than JPGs of the same page, but they reproduce the page exactly.

Example

A US Letter page (612 × 792 pt) at 300 DPI becomes 612 ÷ 72 × 300 = 2,550 × 3,300 px. The same page at 150 DPI is 1,275 × 1,650 px — a quarter of the pixels.

When the transparent option helps

Vector PDFs such as logos, icons, charts or signed signature pages contain no paper colour, so with a transparent background you can drop the PNG straight onto a slide or a web page. Scanned documents are photographs of paper: their background is part of the image and stays white.
