    As far as I can tell, imageoptim eats this project's lunch. The examples given on optimage's own benchmark page show imageoptim clocking in at around half the total filesize of optimage for the entire benchmark.

    Even in the specific examples that are supposed to count against imageoptim -- the destructive chroma sampling, the 'broken gradient' (I can't see it), the orange sneakers (imageoptim's looks better and not overblown colors), or the rotated beach scene -- imageoptim is dramatically smaller on all of them. It puts up a 76k file vs 141k, a 5k vs 14k, a 72k vs 177k, and a 750k vs 1340k.

    Halving the filesize for such small differences is exactly what I want in an optimizer.

    My biggest complaint with imageoptim is that it's primarily a mac tool, with only a secondary online interface for the windows/linux crowd. But then this project has exactly the same flaw, so there's no gain there either.

    > First tool for automatic image compression that just works

    If you search "image compression tool" on Google you'll have millions of hits of products that do the exact same thing. You even list a bunch of competitors on your website. What makes this the first?

    FYI in firefox (62.0.2) some 'before' images look different.

    In chrome they look identical. Perhaps the source images included gamma information?

    CRS-4 Mission Launch by SpaceX (less contrast, less color saturation in 'before')

    Jellyfish photo by 贝莉儿 NG (much lower blue saturation in 'before')

    Pedantic quibble: shrinking is optimizing for size. I deal with a lot of shitty images and size is the last thing I care about. I'm sure it does a great job at making things smaller but that's not the only kind of optimization there is.

    Shameless plug: https://recompressor.com

    Does something very similar, but gives you a full trade off graph and also supports SVG and is free.

    I currently use ImgBot[1] to optimize all my assets in my GitHub repo. Works well.

    Off-topic, but at the bottom of the page there is this quote from Jay Walker at TED 2008:

    > “It takes the energy in one lump of coal to move 1 MB of information across the net.”

    I wonder if it's still true today, 10 years later.

    Any plans of supporting other systems? Linux perhaps?

    For me, squashing images is most useful when creating thumbnails. This makes pages load much faster due to the smaller file size. In this sense, optimage would be more useful if it could also intelligently crop the image down to a square.

    Could you do this as an Adobe (Photoshop) add-on? Wouldn't that be a bigger market?
