What this tool does

Extract Images runs poppler's pdfimages over your document and writes out every raster image the file actually stores. What you get back is a copy of the stored resource, not a picture of the page: a photograph placed at thumbnail size in a report still arrives at whatever resolution it was saved at, which is usually the reason for extracting rather than screenshotting.

The distinction worth understanding first is what counts as an image. Text, rules, tables and anything drawn as vector paths are instructions the viewer follows when it paints the page, not pictures the file carries, so nothing is written for them. A scanned document is the opposite case — every page is one full-page image — so extraction hands back the page scans themselves rather than the photographs printed on them. When you want the page as it looks, PDF to PNG renders it instead.

Two settings decide what survives. Ignore images narrower than reads the width out of each extracted file's own header and drops anything below the threshold, which is how hairline separator rules and sixteen-pixel bullet icons stop cluttering the result; an image whose width cannot be read is kept rather than guessed at. Skip repeated images compares the bytes of each file and discards exact duplicates, so a masthead drawn on forty pages comes back once — though a logo re-encoded slightly differently on each page is not byte-identical and will come back forty times.

None of this happens in the browser tab. Your PDF is uploaded over an encrypted connection to a machine running pdfimages, and both the upload and the extracted files are removed automatically once the retention window passes, a matter of hours rather than something kept. The ceilings are worth knowing before you start: 200 MB per upload, 1,000 pages per document, two minutes of processing, and at most 500 images returned from one run. A document with no stored raster images at all fails with that message instead of handing back an empty archive.

How to use it

  1. Upload the PDF. One document per job, up to 200 MB and 1,000 pages. A file that demands a password to open cannot be read — remove it with Unlock PDF first.
  2. Set the minimum width. The default of 64 px clears out separator rules, bullets and spacer graphics. Drop it to 1 px when you genuinely want every stored image, however small.
  3. Choose the Save as encoding. Original encoding copies JPEGs out untouched and writes everything else as PNG. PNG converts the lot. JPG writes only true JPEGs as .jpg.
  4. Decide about repeats. Skip repeated images is on by default, so a header, watermark or logo that appears on every page is returned once instead of once per page.
  5. Collect the files. Images come back as img-000, img-001 and so on in document order, with badges counting what was skipped. Download all as ZIP takes the set in one go.

Common use cases

Recovering artwork from a supplied PDF

The designer sends the finished brochure but not the source photographs. Those photographs are still inside the file at the resolution they were placed at.

Reusing a chart or photograph from a report

Screenshotting is how most people try to get pictures from PDF pages, and it costs you everything above screen resolution. The embedded file usually prints.

Getting the page scans out of a scanned document

A scan stores one image per page, so this is the quickest route to the raw page images for retouching, deskewing or OCR somewhere else.

Auditing what a document is carrying

An image cropped to a corner on the page is still stored whole, so extraction can show what the crop was hiding before the file goes any further.

Questions

Is my PDF uploaded?
Yes. pdfimages runs on the server, so the document is sent over an encrypted connection, processed there, and deleted along with the results when the retention window expires. Tools that need no upload at all, such as PDF to PNG, carry a "Runs on your device" badge instead of this one.
Why does it say the PDF contains no images?
Because nothing in it is a stored raster image. A document typeset from text and vector drawings carries no pictures to pull out, however illustrated it looks. Render the pages with PDF to PNG if an image of the page is what you need.
Why are the images larger, or cropped differently, than they look on the page?
You get the stored resource, not the placed appearance. Cropping, scaling, rotation and masking are applied by the page as it is drawn, so an image shown small and turned on its side still arrives whole and at full size. It also arrives in the orientation it was stored in, which is not always the orientation the page shows: a picture the page turns upright can come out lying on its side, and the fix is a quick rotate afterwards.
Which Save as option should I choose?
Original encoding in almost every case: JPEGs are copied out byte for byte with no re-encoding, and everything else is written as PNG. PNG converts everything, which is safe but larger. JPG writes only genuine JPEGs as .jpg — other images come out as .ppm or .pbm netpbm files that most software will not open.
Why do the filenames skip numbers?
Numbering follows the order images are found in the document and is assigned before the filters run. A gap means the image at that position was dropped as too narrow or as a repeat, and the badges on the result say how many went each way.
What if a run returns more than 500 images?
The set is cut off at 500, and the two-minute processing limit applies as well. Past the 999th image there is a further wrinkle: the extracted files are put in order as text rather than as numbers, so img-1000 sorts ahead of img-999 and the 500 you keep are no longer the first 500 in the document. An image-heavy file is better divided with Split PDF first, then extracted a part at a time.
Does extraction change the image quality?
No setting degrades it. Original encoding copies a stored JPEG out exactly as the PDF holds it; PNG re-encodes from the decoded pixels, which is lossless but bigger; JPG leaves genuine JPEGs alone and writes everything else as uncompressed netpbm, which is bulky and awkward to open rather than lossy. Nothing here re-compresses a photograph a second time.
