Batch Resize

Why

As of 2018, the OSE wiki has a strict upper file size limit of 1M as our OSE Server infrastructure is operating on a very limited budget. For more information on why this is necessary, see Mediawiki#.24maxUploadSize

Imagemagick

All it takes is one line to resize a directory full of images to your desired size if you have the ImageMagick tools package installed. convert is a tool that comes with that package.

To install ImageMagick, go to Terminal and type: (on Debian/Ubuntu based systems)

sudo apt-get install imagemagick

To resize only, go to the directory of interest:

find . -iname '*.jpg' -exec convert {} -resize 640x480 {} \;

find . -iname '*.jpg' -exec convert {} -resize 960x720 {} \;

To resize and convert to another format (example converts JPEG to PNG):

find . -iname '*.jpg' -exec convert {} -resize 640x480 {}.png \;
