Site optimization: it’s all about your image size and format
I really like this small Firefox extension Smushit as it allow to quickly check if all my images are optimized for the best size and thus speed of rendering. But wait IE/Opera/Chrome can still use this bookmarlet 🙂 to optimize the images found on any web page!
Image optimization is an art that not many people master. There are many good image editing tools that allow us to get the best visual result for a certain file size but "under the hood" a lot more optimization can be done.
Smushit.com is a service that goes beyond the limitations of Photoshop, Fireworks & Co. It uses image format specific non-lossy image optimization tools to squeeze the last bytes out of your images – without changing their look or visual quality. You’ll get a report of how many bytes you can save by optimizing your images and all the changed images as a single zip for download.
Saving bytes has never been so easy – you point us in the right direction, and we’ll do the rest for you. A ZIP archive with optimized images will be generated for you.
