Converts PDFs to JPG, JPEG, PNG, or WebP images via ImageMagick and Ghostscript under the hood: render specific pages or all of them, control output quality/DPI/dimensions/background color, read page count and page dimensions, and handle password-protected PDFs. Requires ImageMagick 7 specifically (not the older ImageMagick 6 many systems still ship), since it relies on API changes introduced in that major version.
