What happens to your file

Everything below happens inside your browser, on your own device. The PDF is not uploaded, so nobody else, including us, can see it.

  1. Your browser opens the PDF with pdf-lib and follows each page’s drawing instructions, including pictures placed inside reusable blocks, to list the pictures in the order they appear.
  2. JPEG pictures are copied out exactly as they are stored. The bytes in the downloaded .jpg file are the same bytes that are inside the PDF, so nothing is lost and nothing is compressed again.
  3. Pictures stored in other ways, such as raw pixels, black-and-white scans, palette images, JPEG 2000 or pictures with a transparent background, are drawn at their exact pixel size by pdf.js, the PDF viewer built into Firefox, and saved as PNG, which loses nothing.
  4. A JPEG whose colours would come out wrong on its own, for example one the PDF shows inverted, is saved as PNG instead, so the colours match what you see in the PDF.
  5. The same picture used on many pages is saved once. Tiny pictures under 32 pixels, which are usually lines, bullets or dots, are left out.
  6. If photos carry hidden details from the camera, such as a GPS location, you can remove them before downloading. Only those details are cut out of the file; the picture data is not touched.
  7. The ZIP file is built on your device and saved straight to your downloads.

How to extract images from a PDF

  1. Choose a PDF or drop it on the box. pdfMB counts the pages and checks that it can open the file.
  2. Press “Extract images”. Every page is searched, and a bar shows how far it has got.
  3. All pictures appear in a grid with their page number, size in pixels and format. Tap a picture to leave it out, or press “Clear” and pick only the ones you want.
  4. Press the download button. One picture is saved as a single file, several are saved together in a ZIP. You can also save any picture on its own with its “Save” link.

Which format each picture comes out in

JPEG photos

Saved as .jpg, byte for byte as stored in the PDF: the same size and the same quality.

Pictures with a transparent background

Saved as .png with the transparency kept, so logos and cut-out pictures stay cut out.

Scans, diagrams and screenshots

Black-and-white scans, palette pictures and pixels stored without JPEG are saved as lossless .png.

Print pictures in CMYK

JPEG pictures in print colours are copied as they are when their colours display correctly on their own. Otherwise they are saved as PNG.

When people use it

Reusing photos from a report or brochure

Get the original photos out of a PDF to put them in a presentation or on a website, without the blur of a screenshot.

Recovering pictures you only have as a PDF

When the original files are lost but the PDF survives, the pictures inside it are often the full-quality originals.

Logos and graphics with transparency

Logos stored with a transparent background come out as PNG files that are still transparent.

Checking what a PDF contains

See every picture a file carries, including ones that are hard to notice on the page, and whether any photo still carries a GPS location.

What it can’t do

  • Drawings made of lines and shapes, such as most charts and logos made in Word or Illustrator, are not pictures and are not extracted. Use PDF to JPG to save the whole page as a picture.
  • Scanned pages come out as one big picture per page, because that is how scanners store them.
  • Very small pictures stored directly inside the page’s drawing instructions (inline pictures) are not extracted.
  • A picture that was cropped on the page comes out whole, as it is stored in the file.
  • Non-JPEG pictures larger than 16 million pixels, or wider than 8,000 pixels, are saved smaller as PNG because of the browser’s size limit. JPEG pictures are never resized.
  • Password-protected PDFs need the password removed first.

Questions about extracting images from PDF

Is my PDF uploaded?

No. pdfMB extracts the pictures inside your browser, and the file never leaves your device. You can check this in your browser’s network tools.

Do the pictures lose quality?

No. JPEG pictures are copied byte for byte, and all other pictures are saved as PNG, which is lossless. Nothing is compressed again.

Why are some pictures PNG and others JPG?

Each picture keeps the kind of compression it already had. JPEG photos stay JPEG. Pictures stored any other way become PNG, so no detail is lost and transparency is kept.

How is this different from PDF to JPG?

PDF to JPG takes a picture of each whole page, with its text and drawings. Extract images saves only the pictures embedded in the file, at their original size.

Why is a picture missing?

Charts and logos drawn with lines and shapes are not pictures. Tiny pictures under 32 pixels and repeats of the same picture are also left out.

Do the photos keep their location data?

By default the files are exactly as stored, so yes. If a photo carries a GPS location or camera details, pdfMB tells you, and you can remove them before downloading.

Is there a page or size limit?

There is no fixed limit. Very large files can run out of memory on some phones.
