About extract pdf images

This is a different job from PDF to JPG and the distinction catches people out. Converting to JPG photographs the page — you get a picture of the whole layout, text and all, at whatever resolution you rendered it. Extracting images reaches into the file and pulls out the picture objects that were embedded in it, at the resolution they were stored at, without the surrounding page.

The difference shows up immediately in quality. A product photograph embedded in a brochure at 2000 pixels wide is still 2000 pixels wide inside the file, even though the page displays it at three inches. Render the page at screen resolution and you get a 300-pixel version of that photograph. Extract it and you get the original. For anything where you want the picture rather than the page, extraction is the only approach that preserves what is actually there.

The tool walks each page's operator list with PDF.js, collects the image objects it references, and decodes them to bitmaps in the tab. Duplicates are filtered, because a logo repeated in a header appears once per page inside the file and you do not want forty copies of it. Very small images are filtered too, since bullet points, rules, and spacing artefacts are technically images and clutter the results without being useful.

Two honest limits. Scanned documents contain exactly one image per page — the scan itself — so extraction returns the same thing as rendering, just at the scanner's native resolution rather than yours. And some PDFs store images in ways that resist clean extraction: tiled into strips, masked into unusual shapes, or encoded in formats without a browser decoder. Where an image cannot be decoded cleanly it is skipped rather than saved broken, so if a picture you can see is missing from the results, that is why.
