In this article, we will consider how to compress graphics with modern methods with minimal impact on quality. The smaller the image size, the more convenient it is for users - especially with mobile phones. Blink-based browsers automate resource selection with client-hints- and you will save traffic on users who have specified the "data saving" option in the browser via the Save-Data hint. There are tools for generating and issuing srcset. This can be used when choosing a format for output: for example, the WebP format for Blink-based browsers, such as Chrome, and the JPEG / PNG option for other browsers.Ĭompression can always be improved. Some browsers announce support for image formats via the Accept header. When there is an opportunity to spend a couple of CPU cycles, and you need a better quality image and you are ready to put up with a long coding time, then try Guetzli. Instead of crazy giant animated gifs, give H.264 videos to users (or WebMfor Chrome, Firefox and Opera)! If you can't afford it, then at least use Giflossy.

To automate the build, use imagemin or libvips. It's easy to forget about it, recommendations change, and the content itself can easily slip past the assembly line. Optimization of graphics must be automated. Image compression should always be automated. I have run ImageMagick identity on the image 3 times.The author of the e-book is Eddie Osmani, one of the managers of Google Chrome. Can this be automated? I am running Windows. I have also tried this on Photoshop using 'Save for Web', and this method strips out the color profile, but I don't want to do this for ~500 images, and File > Automate > Batch in CS6 doesn't have any Action for Save For Web.
