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.
