Recommended Tool: JPEGmini
Our team is constantly on the lookout for apps and services that allow us to work smarter. A few months ago we discovered JPEGmini for reducing the size of images uploaded to the web.
This is one of the first tools we've come across that preserves the quality of our images while dramatically reducing their size. This helps keep upload times down and also helps to keep optimize your images for storage in Osmek. Enjoy!
