online image compression tool. Author is seriously techy and claims it's the best online tool. See his articles about png and jpeg

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

Squoosh
they say: Squoosh is an image compression web app that allows you to dive into the advanced options provided by various image compressors. A google project.
Anselm Hanneman says: lets you optimize images perfectly in your web browser. It’s made by the Google Chrome team and as a bonus you can also resize the image and choose which compression to use, including mozJPEG and WebP.
Doesn't work with Epic - use Firefox or Chrome.

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.

Kraken Image Optimizer · Kraken.io
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.
