PDF to PNG Converter: Free Online

To convert a PDF to PNG, drop the PDF into the box above and click Convert all. Each page becomes its own PNG and gets its own row in the list, with a Download button as soon as it's ready. Once two or more pages are done, a "Download all as .zip" button appears too. You can drop several PDFs at once; they're done one after another.

Need only some of the pages? Type them in the Pages box before you convert: "3" for one page, "1-4, 9" for a few, "10-" for page 10 to the end. Leave it empty and you get every page. This is the reverse of our image to PDF converter, which puts PNG and JPG files into a PDF instead of taking them out.

Resolution decides how many pixels each page gets. 150 DPI is the default and right for most screens: a Letter page comes out at 1275 by 1650 pixels. Pick 300 DPI for print or for zooming into small text (2550 by 3300 for the same page), or 72 DPI for a quick, small preview. PNG doesn't throw detail away when it compresses, so there's no quality slider to worry about. The JPG option next to PNG gives smaller files, at the cost of slightly soft edges around text.

Nothing is uploaded. Your browser opens the PDF with PDF.js, the same engine Firefox uses to show PDFs, and draws each page in a background worker so the page stays responsive on a long document.

You can also do this without a website, with some limits. On a Mac, open the PDF in Preview, choose File, Export, and set Format to PNG; Preview saves one page at a time, so a 20-page PDF means 20 exports. Windows has no built-in PDF to PNG option, so people usually take a screenshot with the Snipping Tool, which only captures what fits on the screen at screen resolution. On an iPhone or Android phone, a screenshot is the usual route too. This page works in Safari and Chrome on phones as well, and saves every page at a resolution you pick.

Say you have a 24-page PDF report and need the chart on page 7 for a slide.

Drop the PDF in, type 7 in the Pages box, and leave resolution on 150 DPI. Click Convert all, and a second or two later there's one row, "report.pdf (page 7 of 24)", with a Download button. You get report-page-07.png, about 1275 by 1650 pixels for a Letter-size page. No need to render the other 23 pages and hunt for the right one.

If the chart has small labels that need to stay readable when the slide is projected, set 300 DPI and convert again. The PNG doubles in width and height, and the file grows roughly three to four times. For a whole document, clear the Pages box, convert, and use "Download all as .zip" to get every page in one go, named in page order.

A PDF page is mostly a set of drawing instructions: text in its fonts, vector lines, and any photos embedded in it. Converting PDF to PNG means following those instructions once, at a fixed size, and saving the result as pixels. That's why resolution matters more than anything else here. At 72 DPI the page is drawn small and small text gets fuzzy; at 300 DPI the same page has over 17 times as many pixels and holds up in print.

PNG compresses losslessly, so what was drawn is exactly what's saved. That suits pages of text, charts, diagrams and screenshots, where JPG's compression would leave faint smudges around every letter. The trade-off is size: a page of photos saved as PNG can easily run to several megabytes, and that's when the JPG option makes sense.

Two honest limits. The PNG is a picture of the page, so the text in it isn't selectable or searchable any more. And the background is white, not transparent, because that's how a PDF page looks; if you need a logo with a see-through background, export it from the original design file instead. Very large pages, like A0 posters or engineering drawings, are drawn at up to about 16.7 million pixels, so they work in every browser, phones included; at 300 DPI that means a poster comes out nearer 100 DPI.
