Previously a Senior Engineer at BSkyB—one of the UK’s largest media organisations—he now helps companies of all shapes and sizes with their JS architecture, front-end performance, and more. He is the developer of popular image optimisation tool ImageOptim-CLI, and Tweets about all things front-end at @fold_left.
We usually export images for the Web from our favorite graphics software. Our eyes fixate on an image’s preview, adjusting the quality settings until we’ve found that sweet spot, where the file size and quality are both the best they can be. After having gone to all that care and effort, we would be forgiven for thinking that our image is in the best shape possible, but that’s not always the case. In fact, much more data is usually left in such files, data that keeps our users waiting just a bit longer than necessary. Thankfully, a number of popular tools can help us optimize images even further!
