Quick resize image in Debian

On macOS it is so convenient to just right-click an image in the Finder and change its size right there.

This is how you can setup a similar behavior in Linux.

You need install imagemagick, I’m using Debian so I installed it like this:

sudo apt install imagemagick

Then create the following script:

nano ~/.local/share/nautilus/scripts/resize_800x600.sh

and put the following code in there:

#!/bin/bash
for file in "$@"; do
    convert "$file" -resize 800x600 "${file%.*}_small.${file##*.}"
done
notify-send "Image Resizer" "Resize complete!"

The restart Nautilus with this command:

nautilus -q

That’s it. Now you can very quickly resize images right in the Files.
