My opinions and beliefs may differ from those of my current and past employers.
"We're excited to announce Guetzli, a new open source algorithm that creates high quality JPEG images with file sizes 35% smaller than currently available methods, enabling webmasters to create webpages that can load faster and use even less data."
I was excited to see this post today and started testing out the tool by downloading the build from Github. I ran through an example image that I had already pre-optimized using other JPG optimization tools, such as JPEGMini and OptImage. The image was at the point where I could not compress or optimize it further without it introducing too many artifacts and blurring the text. Using Guetzli, I was able to reduce it from 94KB to 80KB without any difference I could perceive visually. Glad to see we're still pushing forward to optimize images and further reduce data loads on the web.
I cobbled together a simple Guetzli batch processing script/service for Mac. However, I believe they are updating the tool to support some batch processing natively. I still highly recommend learning and using scripts and things like Automator for Mac. They are powerful tools for putting together workflows.
