PNG is the right format when a PDF page has to stay sharp. It is lossless, so text edges and thin lines survive the conversion exactly as they were drawn, and it keeps transparency where the page has none. That is the difference between a screenshot you can read and one that looks slightly smeared.
This converter renders each page of your PDF at twice its natural size and saves it as a PNG. The whole thing runs inside this tab using your browser's own PDF engine, so the file is never uploaded, never queued behind other people's jobs, and never stored on a server. Close the tab and nothing of it remains anywhere.
How to convert PDF to PNG
- Add your PDF. Drag the file onto the box above, or click it to browse. The file is read directly by this page and does not leave your device.
- Convert. Press Convert PDF. Each page is rendered in turn and the progress shows which page is being processed.
- Download. A single page downloads as one PNG. A multi-page PDF downloads as a ZIP containing one numbered PNG per page, so you get one file instead of one download prompt per page.
Why convert a PDF to PNG at all
The usual reason is that something needs an image and will not take a PDF. Slide decks, forums, chat apps, CMS uploads and design tools all accept PNG and many refuse PDFs outright. Turning the page into an image sidesteps the format argument entirely.
The second reason is control. A PDF page can reflow or render differently depending on the reader and the fonts it has available. A PNG is fixed. What you see is what everyone else sees, on any device, forever.
What PNG preserves that JPG loses
JPG compresses by discarding detail it judges you will not miss. On a photograph that is a fair trade. On a page of text it is not: the algorithm sees thousands of hard black-to-white edges and smears them, producing the faint grey halos around letters that make a converted document look second-hand.
PNG does not do this. It compresses losslessly, so the pixels that come out are the pixels that went in. For a page of 10pt text, that is the difference between legible and nearly legible.
Frequently asked questions
- Does my PDF get uploaded to a server?
- No. The conversion runs entirely in your browser using pdf.js. The file is read into memory on your own machine, rendered to a canvas, and saved back out. No copy is transmitted, which also means there is nothing on our side to leak or delete.
- Is there a file size or page limit?
- There is no limit imposed by us, because there is no upload to time out and no server bill to meter. The practical ceiling is your device's memory. Very large PDFs, roughly a few hundred pages, will use a lot of RAM while rendering because every page is held as an image until the ZIP is built.
- Should I choose PNG or JPG?
- Choose PNG for anything with text, diagrams, screenshots or line art, because it is lossless and will not blur edges. Choose JPG for photographic pages where the file size matters more than perfect fidelity. A PNG of a text page is typically larger than the JPG, which is the cost of keeping it exact.
- What resolution are the images?
- Each page is rendered at twice its native size, roughly 144 DPI for a standard document. That is chosen so the result stays readable when opened at full size rather than looking soft, which is what happens at the PDF's default 72 DPI.
- Why is a multi-page PDF downloaded as a ZIP?
- A ten-page PDF becomes ten images. Downloading them individually would mean ten separate browser prompts, so they are bundled into one ZIP with each page numbered in order.
- Does it work offline?
- Yes, once the page has loaded. The conversion needs no network access, so it keeps working if your connection drops mid-job.
