Thanks a lot for this!

Thanks a lot for your work! I've ported this script to Windows, here you can find my gist https://gist.github.com/agurz/7c72653bf1923804f26b8c0211de4669

Hin: you need to have ghostscript installed for this as imagemagick relies on it. If it's missing you might see an error like

convert: FailedToExecuteCommand `'gs' -sstdout=%stderr -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r300x300'  '-sOutputFile=/var/folders/w_/bn46lxks695dg9yvvrgx_xnm0000gn/T/magick-23598b4Fr54IpZ4vE%d' '-f/var/folders/w_/bn46lxks695dg9yvvrgx_xnm0000gn/T/magick-23598hwvO5gF963Ot' '-f/var/folders/w_/bn46lxks695dg9yvvrgx_xnm0000gn/T/magick-23598JknpjTH6yPWj'' (1) @ error/pdf.c/InvokePDFDelegate/291.
convert: no images defined `0002.jpg' @ error/convert.c/ConvertImageCommand/3275. ```

Thanks a lot for the script!

Thanks for clearing that up!

Very Nice. Thanks

Simpler solution is to just use pdftoppm:

pdftoppm -jpeg {pdf file} {output folder}

Install with sudo apt install poppler-utils.
