Convert PDF to PNG free

DukPdf's PDF to PNG tool renders pages as lossless PNG images in your browser. PNG stores every pixel exactly, so text edges and thin lines stay sharp instead of picking up the grey haloing JPEG leaves behind. No server uploads, no watermark. If you are working to a file size limit, there are versions set up for it already: under 200KB, under 100KB, under 50KB, under 150KB, under 500KB, under 1MB and under 2MB. For print, use 300 DPI. Not sure which format you want? PNG or JPG for PDF pages covers where the line falls.

A common scenario

You need a page from a manual or a diagram for documentation, and a JPG would soften the text edges enough to look wrong next to real text.

Why privacy matters here

Cloud converters upload the whole document and render every page on their server. DukPdf draws the pages locally in your browser, so the PDF never leaves your device. See how local processing works.

Convert PDF to PNG free — questions

Why choose PNG over JPG?

PNG is lossless, so text edges, thin lines and flat colour come through exactly as drawn. JPG discards detail to save space, which shows as faint grey haloing around letters. For a photographic page, JPG is the better choice — it is far smaller for output most people cannot tell apart.

How do I get a PNG under a specific size?

Use one of the size-targeted pages above. PNG has no quality setting, so the only way it can get smaller is to render fewer pixels — a tight target produces a physically smaller image rather than a blurry one.

Will the PNG have a transparent background?

No. PDF pages are rendered onto white before they become images, so the result is opaque. PNG supports transparency, but there is none in the source to preserve.

Is the PDF uploaded?

No. Rendering runs in your browser using PDF.js and an HTML canvas. Open DevTools and watch the Network tab during a conversion — there are no upload requests carrying your document.
