PDF to PNG at 300 DPI

How to Convert PDF to PNG

1

Add your PDF

Click “Select files” or drag a PDF in. Quality is already set to High, which renders every page at 300 DPI.

2

Leave the size target off

No size limit is applied here on purpose. Capping the bytes would shrink the dimensions, which is the opposite of what this page is for.

3

Convert and download

Click “Convert to PNG”. Rendering at 300 DPI lossless takes longer and uses more memory than the default, so give a long document a moment.

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

Why use this tool

This page renders PDF pages to PNG at 300 DPI, the resolution commercial printing expects. An A4 page comes out around 2480 by 3508 pixels. Because PNG is lossless, that is a genuinely exact copy of the page — no JPEG ringing around letters, no blocking in flat areas, nothing at all discarded. It is the combination people mean by “high quality”, and it is what PNG is for. The cost is size: several megabytes per page is normal here and is not a problem to fix. The size target is deliberately left off, because capping the bytes would force the dimensions back down and undo the resolution. For screens, 150 DPI looks identical and produces files a quarter of the size. If the result is too large to send, target a size instead with PDF to PNG under 500KB.

When you'd use this

Print production

Posters, brochures and flyers going to a commercial printer, where 300 DPI is the floor and JPEG artefacts would show on paper.

Design file placement

Placing a page into Figma, Illustrator or InDesign as a raster layer that stays clean when scaled.

Archival line art

Schematics and drawings where a lossy format would smear thin strokes into grey and 300 DPI keeps them exact.

Detail inspection

Zooming into small print or a fine pattern, where you need the original pixels rather than an encoder’s approximation of them.

PDF to PNG β€” questions

Can I go higher than 300 DPI β€” 600 or 1200?

Not on a full page. The renderer caps any image at 8192 pixels on its longest side, which on A4 works out at roughly 700 DPI. 1200 DPI would need about 9,900 pixels, so it is not available here whatever the setting. In practice 300 DPI is what printers reproduce anyway.

Why choose PNG over JPG at 300 DPI?

Because at print resolution the artefacts are what you notice. JPEG leaves faint ringing around every letter edge and blocking in flat areas — invisible on a screen, visible on paper. PNG has neither, at the cost of a much larger file.

How large will the files be?

Several megabytes per page is normal, and for a photographic page it can be considerably more. That is the point of the format — nothing has been thrown away. If size matters more than fidelity, use PDF to JPG at 300 DPI.

Does 300 DPI improve a low-quality scan?

No. Rendering at a higher resolution cannot add detail the PDF never contained. If the source was scanned at 100 DPI, a 300 DPI export is the same picture with larger pixels.

What is the difference between 300 DPI and 300KB?

They measure different things. DPI is how much detail the page holds; KB is how large the file is. A 300 DPI PNG is usually several megabytes — many times 300KB. The two are frequently confused because the number is the same.
