ImageOptim

Thanks to the developer Kornel Lesiński and all 3rd party related developers for this great app! Cloud storage space and data transfers come at a cost, and whenever possible, size of a file should be reduced. Especially so when a file is shared with other people—thinking in the best interests' of others always pays off. ImageOptim is very helpful in this regard.

★★★★★ A long-time favorite with many photographers for fast & easy optimization of PNG and JPEG images for web use. Highly recommended! Support development with a donation if you enjoy using it!

Very nice, this update includes SVG optimisation!!! This adds to an already totally brilliant and essential tool for anyone. I use it to optimise figures before creating PDFs as I have more control in ImageOptim than any of the PDF optimising tools... It works just brilliantly, and integrates with services, so for example for screenshots I use a service that resizes the screenshot 50% and then runs automagically through ImageOptim with lossy enabled to get a PNG reduced by more than 80% in size on average from the original!

It is really not bad for a free app. Recommend

Nice app. Comprehensible. Easy to use.

Any possibility to have an option to disable automatic installation of new updates?

Still the only app I've ever encountered that insists on auto-updating without user intervention, and without providing a means of disabling it. The only warning you get is the sudden appearance after quitting the app of a dialogue advising that, "Autoupdater" would like to make changes to the system. Not a single mention of ImageOptim anywhere in that dialogue. The only clue is when you look in the Trash and see the discarded version there. The dev, when contacted, could offer no good reason for this behaviour, and refused to change it. I've disabled it manually, but this shouldn't be necessary.

This is an excellent update, allowing a temporary lossy option and an extension to compress images *within* Mail, really great!
