No. This tool only extracts raster (bitmap) images, the same standard most PDF image extractors follow. Vector graphics are drawn with drawing instructions instead of being stored as a separate image file, so there's nothing to pull out as a file.

This tool pulls out only the individual images embedded inside a PDF's pages, saved as separate image files. Extract Pages instead saves whole pages, images and all, as a new PDF.

This tool pulls out the images already embedded inside a PDF, like photos or logos, and saves them as separate files. If what you actually want is to turn each PDF page into a full JPG image, including the surrounding text and layout, that's the PDF to Image tool instead.

No. JPEG and JPEG2000 images are copied through untouched, and every other format is saved as a lossless PNG, so nothing gets recompressed or degraded.

No. Everything runs directly in your browser. Files are never sent to a server, so your document stays on your own device.

Dely PDF simply produces an empty result instead of an error, since there's nothing embedded to extract.

Yes. Add multiple files and every image from all of them is saved into one ZIP, though processing more than one file at a time is a Dely PDF Pro feature.
