Turn PDF pages into PNG images

Sometimes you need a page of a PDF as a picture: to put a chart into a slide deck, to post a page on a website, to attach a diagram to a support ticket or to feed a scanned page into an OCR app. This PDF to PNG converter renders every page you choose as a lossless PNG image at the resolution you pick. Preview the pages, save the ones you want, or download the whole set as a ZIP. The PDF is opened and rendered inside your browser, so it never leaves your device.

Features

  • Lossless PNG output that keeps text edges, thin lines and flat colors perfectly crisp.
  • Three resolutions — 72, 150 and 300 DPI — for previews, screens and print.
  • Page selection with ranges such as 1-3, 8, 10-12.
  • Instant previews of each converted page.
  • ZIP download for multi-page documents, or click a single image to save it.
  • JPG option in the same tool when you need smaller files.
  • Private and free: no upload, no sign-up and no watermark.

PNG or JPG: which format fits your PDF?

Page content Best format Why
Text, tables, code PNG Sharp letters with no compression halos
Charts, diagrams, line art PNG Flat colors and thin lines stay clean
Screenshots inside a PDF PNG Pixel-exact copies of the original
Photos, brochures, scans JPG Much smaller files with little visible loss

If you mainly want small files for email or chat, the PDF to JPG converter starts with JPG selected.

How big will the images be?

The pixel size depends on the page size and the resolution. An A4 page is 595 × 842 pixels at 72 DPI, 1240 × 1754 at 150 DPI and 2480 × 3508 at 300 DPI. A US Letter page is 612 × 792, 1275 × 1650 and 2550 × 3300 pixels respectively. Because PNG is lossless, file size grows with the number of pixels and the amount of detail on the page: a mostly white page of text compresses well, while a page full of photos produces a large file.

Common uses

Slides and documents: paste a chart or table from a report into PowerPoint, Keynote or Google Slides without blurry edges.

Websites and documentation: publish a page from a manual or a datasheet as an image that loads in any browser.

OCR and data extraction: text recognition works best on sharp, high-resolution images; 300 DPI PNG is the usual recommendation.

Design and annotation: open a page in an image editor to highlight, crop or combine it with other graphics.

Tips

  • Convert only the pages you need — it is faster and keeps the ZIP small.
  • For a single page, click its preview to save it directly.
  • To shrink the resulting images further, run them through Compress Image or convert them with PNG to JPG.
  • To go the other way and turn images into a document, use JPG to PDF. To keep some pages as a smaller PDF, use Split PDF.

Frequently asked questions

Why convert a PDF to PNG instead of JPG?
PNG is lossless, so text, thin lines, charts and diagrams stay perfectly sharp with no blurry compression artifacts. JPG makes smaller files and suits photos and scanned pages. For documents that are mostly text or vector graphics, PNG usually looks better.
Which resolution should I use?
72 DPI matches the page size on screen and is good for thumbnails. 150 DPI is sharp on most displays and suits slides and documents. 300 DPI is print quality and the best choice before running OCR; an A4 page becomes 2480 × 3508 pixels.
Will the PNG have a transparent background?
No. Pages are rendered on a white background, the same way they look in a PDF viewer. This keeps text readable in apps with dark themes.
Is my PDF uploaded to a server?
No. Pages are rendered by PDF.js directly in your browser and the PNG files are created on your device. Nothing is sent anywhere.
Why are my PNG files so large?
Lossless images store every pixel exactly. A full page at 300 DPI can be several megabytes. Choose 150 DPI, or switch to JPG if file size matters more than perfect sharpness.
Can I convert a password-protected PDF?
PDFs that need a password to open can't be rendered. Open the file with its password in a PDF app and save an unprotected copy first.
