PDF to PNG
Render each page as a PNG. Lossless, so text edges and line art stay crisp, which is the difference that matters against JPG.
Runs entirely in your browser. Your files are never uploaded.
How to use PDF to PNG
- 1Pick a PDF, or drag it onto the box above.
- 2Choose a resolution. Higher means sharper and bigger.
- 3Narrow it to certain pages if you only need some.
- 4Download the pages one at a time, or grab the lot as a ZIP.
Why PNG rather than JPG
JPG was designed for photographs and throws away detail in a way the eye forgives on a photo and notices immediately on text. Around sharp black-on-white edges it leaves a faint grey halo, which on a page of 9pt type reads as a slightly dirty scan.
PNG stores every pixel exactly. Screenshots for documentation, charts, pages going into a slide deck, anything with small type: this is the one to use. The cost is file size, often three or four times the JPG.
Picking a resolution
A PDF page has no pixels of its own. It describes shapes that get drawn at whatever size you ask for, so the resolution is your decision rather than a property of the file. The number given is the long edge of the image.
1000 pixels reads fine on screen. 1600 is roughly 150 DPI on A4, sharp enough to read closely. 2480 is about 300 DPI and is what a printer wants. The largest option suits A3 or a poster at print quality, and produces files to match.
PNG keeps everything, so this setting drives the output size more than any other. Doubling the resolution roughly quadruples the bytes.
Getting them all at once
Each page downloads on its own, and there is a button that bundles the whole set into one ZIP. The archive is built in your browser from the images already in memory, and it is stored rather than compressed: PNG is compressed already, so deflating it again would cost seconds and save almost nothing.
Transparency
Pages are rendered onto white. PDF pages are transparent wherever nothing is drawn, and a transparent background tends to produce surprises later: black boxes in a slide deck, invisible text on a dark theme. If you need the transparency preserved, the Extract Images tool pulls out the embedded pictures themselves, which keep their own alpha.
Limits
- 100 MB per file.
- Password-protected PDFs need unlocking first.
- Pages are rendered onto a white background.
- A long document at print resolution can exhaust memory on a phone.
Frequently asked questions
- PNG or JPG, which should I pick?
- PNG for text, charts and line art, where JPG leaves halos around sharp edges. JPG for scanned photographs, where the files are far smaller and the difference is hard to see.
- Can I get all the pages in one file?
- Yes, use the ZIP button once the pages have rendered. It bundles everything without re-compressing it.
- Why are the files so large?
- Because PNG is lossless and stores every pixel. A 300 DPI A4 page is around 8 megapixels before compression. Drop the resolution if the size matters more than the sharpness.
- Why is the background white instead of transparent?
- Pages are composited onto white on purpose. A transparent background causes more problems than it solves once the image lands in a slide or a document.
