How to speed up your site with JPEG 2000

JPEG 2000 logo

Most of my posts on the blog have pictures. At some point, pictures have an 800kb size. Some less other more than that. In short: I have a bunch of pictures 4.5MB. So loading my sites was heavy for some users in China, Japan, Australia. Using Google Analytics and sites for web testing - I notice this issue. So the first moment was how to resolve?

I start digging on the net and find that most of my png could be converted to the JPEG 2000 format.

After running command like:

gm convert -define 'jp2:rate=0.008' 20200509173353-twittercard.png 20200509173353-twittercard.jpg

gm command is part of GraphicsMagick package.

Second thing - resizing pictures. Most of my pictures have more then 800x600, so I resize to 640x480. And win drastically speed.

convert 20200509173353-twittercard.jpg -resize 600x400\> 20200509173353-twittercard.jpg

From 4.5MB I went to less than 1MB. Also, I make a faster site to run. Small success but I love it.
