+Image files will usually have the most impact on the speed of your
+websites (aside from Ad/tracker scripts). Learn to slim down your images
+using the ubiquitous *ImageMagick* to make your websites faster on slow
+internet connections.
+
+{{< img alt="Image network speed" src="/pix/imgcompress-network.png" link="/pix/imgcompress-network.png" >}}
+
+For the examples, I decided to use
+[this](https://commons.wikimedia.org/wiki/File:Tabby_cat_with_blue_eyes-3336579.jpg)
+public domain image.
+
+{{< img alt="Compressed image of a cat" src="/pix/imgcompress-cat.png" link="/pix/imgcompress-cat.png" >}}
+
+There are many ways to decrease image size using ImageMagick, the
+simplest is to use the `-quality` option, which will compress the image
+without changing the resolution. This option takes the value you want to
+compress by (between 1 and 100, the lower the value, the lower the file
+size). For example:
+
+    convert in.jpg -quality 50 out.jpg
+
+Compressing the example image above results in the following file size
+changes:
+
+```
+  Quality    Size
+  ---------- ------
+  Original   2.1M
+  90         1.7M
+  80         844K
+  70         588K
+  60         448K
+  50         368K
+  40         308K
+  30         248K
+  20         184K
+  10         116K
+```
+
+Due to the images high resolution, it is usable in this website even
+when highly compressed (30% quality, still looks decent in my opinion).
