Problems with non recommended image attributes (color / grayscale / +300dpi)

[emilioah]

We are having problems with teachers uploading pdf with high resolutions or scanned in color/grayscale mode. Convert uses a lot of memory and sometimes it stops php-fpm.

Maybe it would be good to check uploaded files to honor 300dpi and black-and-white restrinctions before running the conversion.

Hi @emilioah,
thank you for reporting this. We'll have a look on it.

All the best,
