Today I created a new script, it uses Ghostscript behind the scenes to extract all pages from a PDF file, then convert them to individual JPG files.
Because it uses Ghostscript (v9.55.0) latest version, it is a very efficient extraction, converting those PDF pages to high quality (300 DPI by default) JPG files.
It also works in bulk, so you can drag & drop several PDF files on the batch file and all of them will be converted.
I created a new repository in Github PDF-to-JPG-Pages-Extractor, and even made the first PDF to JPG … v1.0.
