 * This plugin does not work with ImageMagick’s current default settings. In order
   to make it work you have to change IM’s settings and thus open a possible security
   hole (cf. “ImageMagick security policy ‘PDF’ blocking conversion” on StackOverflow).
   
   But if you do so, you don’t need that plugin at all, because WordPress then does
   the thumbnail generation out of the box, and those image files only have 10 percent
   the size of those generated by this plugin.

 * YOUR “current default settings” are not really “current default settings” as 
   you are running some old system, old libraries, etc…
 * This was fixed 6 years ago in Ghostscript 9.25 and above…
 * Size of the image file depends on the width, height and compression level, I 
   thought it’s a basic knowledge…

 * Perhaps the reviewer [@bsoftde](https://wordpress.org/support/users/bsoftde/)
   would like to explain how WordPress “does the thumbnail generation out of the
   box”. It certainly doesn’t do so in the same way as this plugin by converting
   each one and saving it in the same location in the uploads folder. I can only
   image you are referring to the ability to use a PDF url directly in an img tag
   to get a preview of the first page? However, this doesn’t give the same flexibility
   that the plugin affords in terms of image dimensions, format, and quality/compression
   level. I’m also guessing that older browsers may not support that style of usage
   either.
