This is an extension that offers similar functionality as JCH-Optimize and JBetolo. Again the main function is combination and minification of your HTML, CSS and JS files. However, the extension offers some more options, which are unique to this extension:
- Images through data-URIs, which results in base-64 encoded strings in your CSS instead of background-images to save HTTP-requests.
- Support for WebP-integration (replace JPG and GIF images with a new image-format (currently only supported by Chrome browsers)
I have not tested this extension yet, but it certainly deserves a place next to the other 2 extensions I mentioned.
