How to extract the images from a PDF at full quality

Pull the original photos and graphics out of a PDF instead of screenshotting them, understand why some PDFs give nothing, and what to do then.

A screenshot of a picture in a PDF is limited to the size it appears on your screen. The PDF itself usually holds the picture at a much higher resolution. Extracting it gets you that original, without the surrounding page.

How pictures are stored in a PDF

A PDF keeps each picture as a separate object, and pages refer to it when they draw. A logo used on every page is usually stored once and drawn many times. Extraction reads those objects directly, so you get the pixels the document actually carries — not a re-rendered copy of the page.

Extract images step by step

  1. Add the PDF to Extract Images From PDF. Each page is scanned as it loads.
  2. Look through the pictures found, with their pixel sizes and the pages they appear on.
  3. Download a single picture, or all of them together as a ZIP.

Nothing is uploaded, so it is safe to use on scanned contracts and private documents.

What you get

  • The stored resolution. If a 4,000-pixel photo was placed small on a page, you get all 4,000 pixels.
  • Each picture once. A logo repeated on every page appears once, listed with all the pages it is on.
  • Lossless PNG files. The pixels are saved exactly. If the picture was compressed when the PDF was made, that compression is already part of it and cannot be undone.

Scanned documents

A scanned page is usually one large image per page, so extraction gives you each page as a picture at full scan resolution — handy for re-cropping a scan or pulling out a single signature or stamp. Black-and-white scans stored at one bit per pixel are handled too.

When nothing is found

Some PDFs give no pictures at all. There are two usual reasons:

  • The graphics are drawings, not pictures. Charts, diagrams and logos made in design or office software are often stored as shapes and text, which are not images.
  • The pictures are stored inline inside the page's drawing instructions rather than as separate objects.

In both cases, render the page instead with PDF to PNG at a high resolution, then crop out the part you want.

A worked example: a figure from a report

You need a chart from page 37 of an annual report for a presentation. Screenshotting it gives a soft image the size of your screen. Instead:

  1. Add the report and look for page 37 in the list of pictures found.
  2. If the chart is listed, download it — you get it at the resolution the report's designer placed.
  3. If it is not listed, it was drawn as shapes; render page 37 with PDF to PNG at a high resolution and crop the chart out.
  4. Credit the source on the slide.

Large files

PNG keeps every pixel, so an extracted photograph can be larger than you expect. To share it, convert it to JPG or WebP with the Image Converter, which can also cap the width.

Who owns the pictures?

Extracting a picture does not change who owns it. Photos and illustrations in brochures, reports and books are usually someone's copyright. Extracting your own images from your own documents, or using a picture with permission, is fine; republishing someone else's is a different matter.
