PDF to PNG — Lossless Page Images

How to Convert PDF to PNG

1

Add your PDFs

Click “Select files” or drag and drop one or more PDFs into the upload area.

2

Choose pages and quality

Convert every page or enter numbers and ranges (1, 3-5, 8). Pick Normal for screen use or High (300 DPI) for print.

3

Convert and download

Click “Convert to PNG”. Pages render on your device; multi-page results are zipped automatically.

Every step runs in your browser. No server uploads, no waiting.

Why use this tool

DukPdf’s PDF to PNG tool renders pages as PNG images in your browser. PNG is the right choice when the page is mostly text, diagrams, tables or line art: it stores every pixel exactly, so edges stay clean instead of picking up the soft halos JPEG leaves around dark text on white. The trade is size — expect PNGs several times larger than the equivalent JPGs, because losslessness has to be paid for in bytes. Rendering is 150 DPI at Normal (about 1240×1754 pixels for an A4 page) and 300 DPI at High, with a hard cap of 8192 pixels on any side. Because PNG has no quality dial, the size row works on dimensions: cap an image at 200KB and it comes back slightly smaller, never blurrier — a page that already fits is exported untouched at full size. If size matters more than sharpness, use PDF to JPG; to decide per job, PDF to Image puts both in one place. To go the other way, PNG to PDF builds a PDF back out of images. Need a specific file size? The size-targeted pages below start with the limit already set. For a step-by-step walkthrough, see our PDF to PNG guide, or PNG or JPG for PDF pages if you are still deciding between the two.

When you'd use this

Diagrams and schematics

Thin lines and small labels survive intact, where JPEG compression would blur and speckle them.

Print and design handoff

Hand a printer or designer page images with no compression artefacts baked in.

Tables and charts for slides

Drop a page of figures into a deck with gridlines and axis text still legible at full zoom.

Archival page images

Keep a pixel-exact record of a document’s appearance that will not degrade if it is re-saved later.

PDF to PNG — questions

Should I pick PNG or JPG?

PNG for text, tables, diagrams and screenshots — anything with hard edges or flat colour. JPG for photographic pages, or whenever file size matters more than perfect edges. PNG files are typically several times larger for the same page; a photo page shows the biggest gap, a text page the smallest.

Why are the PNG files so much bigger?

PNG is lossless: it records every pixel rather than approximating them. That is exactly why text stays crisp, and exactly why the file grows. A typical text page lands around 190KB at Normal quality; a photographic page can run to a megabyte or more at the same setting.

How do I keep the PNGs under a size limit?

Set a target in the size row — from 50KB to 2MB per image. Since PNG has no quality setting, the tool renders the page at the largest dimensions that fit the byte budget, so the image gets smaller rather than blurrier. Each rung has its own preconfigured page, from under 50KB up to under 2MB.

Do the PNGs have a transparent background?

No — pages render on a solid white background, matching how the PDF looks in a reader. A PDF page normally does not paint its own background, so leaving it transparent would produce images that vanish against a dark backdrop.

What resolution do I get?

Normal renders at 150 DPI, which suits screens and most everyday use. High renders at 300 DPI for print — that is what PDF to PNG at 300 DPI preselects. Either way the renderer caps any image at 8192 pixels on its longest side, roughly 700 DPI on A4.

What does a long document produce?

One PNG per selected page, bundled into a ZIP. A 500-page PDF is a 500-image job rendered page by page on your machine — it works, it just takes time and memory in proportion, and no server is involved at any length.

Can I convert only some pages?

Yes. Enter page numbers (1, 3, 7) or ranges (3-5, 8-12) and everything else is skipped — unselected pages are never rendered at all.

Are my PDFs uploaded during conversion?

No. Rendering runs in your browser with PDF.js and a canvas. There are zero upload requests carrying your file.
