Image compression to the smallest file size possible – Compress-Or-Die
online image compression tool. Author is seriously techy and claims it's the best online tool. See his articles about png and jpeg
!! In some usage I saw that colours were really oversaturated and lightened - if you use this, test further with interface colour settings

the original article by Filament about compressive images. From October 2012 so I wonder if there are arguments against this technique now?

JPEGmini - Your Photos on a Diet!
interesting for good jpeg compression. Seems like original has to be a jpeg. Saves a lot if original is compressed at v high quality if original is already very compressed the saving is not important and some extra artefacts were perceivable. V good testing feature on their site.

I tested this on a Tria bag photo and the results aren't great. Colour was very slightly more washed out. Lossy saving on a 100quality jpeg was about 60%, but result was still too big for web use. On an image already compressed to about 12quality, the extra compression saved about 6% but again colour was perceptibly desaturated.
