Pull out the embedded images inside a PDF as separate PNG files.
The actual embedded images themselves — not a rendered screenshot of the page — so you get the original photos/graphics without any surrounding page text or layout around them.
A fully-scanned page is often stored as one single large background image per page — in that case each scanned page image will be extracted as its own file, since that is the embedded image.
Some PDFs store visuals in formats this tool can't decode (like certain CMYK or specially masked images) — if the document is genuinely text-only, there are simply no embedded images to extract.
