ImageMagick is one of my favorite tools ever. I’ve used for years for a whole lot of different things – from simple image resizing, through animation generation, to palette manipulation. And still, I don’t really know it that well, so when I see articles like this – “Efficient Image Resizing With ImageMagick“, I get excited. Not only it gives you a better way of doing things, but it also explains the path of how to get there. From a simple command like:
convert input.jpg -resize 300 output.jpg
to something as advanced as this:
-path OUTPUT_PATH \
-filter Triangle \
-define filter:support=2 \
-thumbnail OUTPUT_WIDTH \
-unsharp 0.25x0.25+8+0.065 \
-dither None \
-posterize 136 \
-quality 82 \
-define jpeg:fancy-upsampling=off \
-define png:compression-filter=5 \
-define png:compression-level=9 \
-define png:compression-strategy=1 \
-define png:exclude-chunk=all \
-interlace none \
-colorspace sRGB \
What’s even more exciting is that it looks like this optimization will make its way into WordPress 4.4, together with some other improvements for the responsive images.

Just wanted to let you all know that I’ve made a couple of changes recently, which should result in a somewhat faster performance of this site.
Firstly, before the last weekend, I’ve moved all my DNS hosting to Amazon Route 53 service. This should result in faster DNS queries all around the globe and minimize the potential downtimes.
Secondly, I’ve installed and configured the JS & CSS Optimizer WordPress plugin, which now results in much fewer HTTP requests needed to load the page, as well as fewer bytes to be transferred around. I’m still tweaking the settings for this one to see how much I can squeeze out of it, but I already see an improvement.
As always, if you see any issues, please let me know.
