PDF to PNG Converter

This page is the PDF to image tool with Image format already set to PNG. It handles one PDF at a time and draws each page onto a white background, the way it would look when printed.

1. Drop a PDF onto the box, paste it, or click to choose the file.
2. Check that Image format reads PNG. The JPG quality slider is shown but does nothing for PNG.
3. Pick a Resolution: Screen (72 dpi), Good (108 dpi), High (144 dpi), which is the default, or Print (216 dpi).
4. Type the pages you want in Pages (empty = all), for example 1-3, 7. Leave it empty to convert every page.
5. Press Convert to images, then download each page or use Download all. Page 4 of report.pdf is saved as report-page-4.png, and the number is padded with zeros when the file has ten or more pages.

Resolution multiplies the natural size of the page, which a PDF measures in points (72 to the inch). A US Letter page is 612 by 792 points, so the pixel size of each result is easy to predict. An A4 page is slightly narrower and taller, about 595 by 842 points.

Higher settings give sharper letters but heavier files, and the time per page grows with them. Each image is capped at 9,000 pixels on its longest side. Only unusually large pages, such as a big poster or architectural sheet, reach that limit, and the result line says when a page was reduced to fit. If you need more than the 216 dpi step offers, convert at Print and enlarge only where necessary.

PNG stores every pixel exactly, which makes it very good at the things PDFs are usually made of: text, lines, charts, logos and flat color. Edges stay clean, with no fuzzy halo around letters. That is why PNG suits slides, diagrams, spreadsheets exported to PDF, and pages that look like screenshots.

It is a poor match for scanned pages and photographs. A scan is really a big photograph of paper, and a lossless copy of it can be several megabytes per page. For those files the PDF to JPG converter produces much smaller images with little visible difference. A sensible test is to convert one page both ways and compare the sizes shown under the thumbnails.

Remember that a PNG made from a PDF is a picture of the page. The text in it can no longer be selected or copied. When the goal is the words rather than the look, the PDF to text converter is the better tool. The white background means transparent areas in the PDF come out white, not see-through.

A single run converts at most 60 pages. With a longer file the tool stops and asks for a range such as 1-30, and you repeat the job with the next block. Password-protected PDFs are refused with a message asking you to remove the password first. A PDF that is damaged or is not really a PDF is reported as invalid.

Each page becomes its own file, which keeps things flexible but leaves you with a pile of images. Download all saves them together. If the PNG files are too heavy for a document or an upload form, shrink them with the image compressor, or reduce their dimensions with the image resizer. To go the other way and gather images back into one document, use the image to PDF converter.

The PDF is opened and drawn with a library that runs in your browser tab. The file is read from your device, held in memory while pages render, and never sent to a server. Large documents at the Print setting use a lot of memory, so on a phone try fewer pages at a time.
