Convert PDF to PNG

How to convert PDF to PNG

1. Drop your PDF onto the box above.
2. Image format is set to PNG. Choose a Resolution: 150 DPI for screens, 300 DPI for print.
3. Optionally type a page range such as 1-3, 5 to convert only some pages.
4. Press convert. One page downloads as a single PNG; several pages come as a ZIP.

Why PNG for PDF pages?

PDF pages are mostly text, lines and flat colour. JPG compression adds faint smudges around sharp edges, which is especially visible on small text and diagrams. PNG is lossless, so every letter, table border and chart line stays perfectly crisp. Choose PNG when you are:

• putting a page into a slide deck, wiki or documentation;
• sharing a chart or diagram as an image;
• capturing a page of a contract or form for a screenshot-style reference;
• preparing images for further editing.

For photo-heavy pages, such as brochures or scanned photos, PDF to JPG gives much smaller files with no visible difference.

Choosing a resolution

Resolution	A4 / Letter page size	Use for
72 to 100 DPI	about 600–850 px wide	thumbnails, previews
150 DPI	about 1250 px wide	screens, documents, slides
200 to 300 DPI	about 1650–2500 px wide	printing, zooming into small detail

Doubling the DPI makes each image about four times larger in file size, so pick the lowest setting that looks good where the image will be used.

Good to know

• Pages are rendered on a white background, exactly as they look in a PDF viewer.
• Password-protected PDFs need to be unlocked before converting.
• To get the images back into a PDF later, use PNG to PDF. To extract pages as a smaller PDF instead of images, use split PDF.

No upload

The PDF is rendered by pdf.js inside your browser, page by page, on your own device. It is never uploaded, and the converter keeps working offline after the first visit.

Frequently asked questions

PNG or JPG for PDF pages?

PNG keeps text and line art perfectly crisp with no blurry artefacts, so it is best for documents, slides and diagrams. JPG makes much smaller files for photo-heavy pages.

What resolution should I pick?

150 DPI is right for screens and documents. Choose 300 DPI for printing or for zooming into small details; files will be about four times larger.

Is the page background transparent?

No. Pages are rendered on white, as they appear in a PDF viewer, so they look correct everywhere.

Are my files uploaded anywhere? How can I check?

No. The PDF to PNG converter runs entirely in your browser using JavaScript and WebAssembly, so your files never leave your device. You can verify it: open your browser's DevTools (F12, or Cmd+Option+I on a Mac), switch to the Network tab, tick "Preserve log", clear the list and process a file. You will only see requests for this site's own static files, never one that carries your data. You can also turn on "Offline" in the Network tab (or disconnect from the internet) once the page has loaded, and the tool keeps working.

Does it work offline?

Yes. After your first visit a service worker saves the tool to your device, so it opens and works without a connection. Only advertising needs the internet; the processing never does.
