PDF → Image

Export PDF pages as PNG, JPG or WEBP up to 300 DPI. Choose pages and download them as a ZIP.

What it does

Sharing one slide on social media, sending a single page in a chat, or reusing a diagram in another app all start with turning a page into an image. This tool exports the pages you choose as PNG, JPG or WEBP at anywhere from 72 to 300 DPI.

Pages are rendered in a separate thread in your browser, so even large PDFs do not freeze the screen. Pick one page and you get an image file; pick several and they arrive together in a ZIP.

How to use it

  1. Drop your PDF file; the thumbnails are rendered in the worker.
  2. Select the pages and choose the format and DPI.
  3. Download: a single page comes out as an image, several pages as a ZIP.

When is it useful?

  • Posting presentation slides on Instagram or LinkedIn
  • Sending one page of a document over WhatsApp
  • Dropping a chart or table from a PDF into a slide deck
  • Making preview images of documents for a website

Tips

  • Choose 150 DPI for screens and 300 DPI for print.
  • Need a transparent background? Pick PNG or WEBP; JPG does not support transparency.
  • To shrink or resize the result, pass it to Compress Image or Resize Image with one click.

Frequently asked questions

Which resolution should I choose?
For screen use 96–150 DPI is enough, and 300 DPI for print. On very large pages the resolution is lowered automatically so the browser limits are not exceeded.
Is a transparent background possible?
Yes, for PNG and WEBP. JPG does not support transparency, so it stays white.
Does rendering block the interface?
No. Every page is rendered in a separate Web Worker using OffscreenCanvas, so the main screen is never blocked.
I want the photos inside the PDF at their original quality.
This tool captures the whole page. To get the original embedded images as separate files, use PDF Extractor.
Why did some pages come out at a lower resolution?
Very large pages, such as A0 posters, are scaled down automatically to stay within the browser's drawing limit. Choose a lower DPI or split the poster into parts.
