mb != MB.

MrEldritch• 7 years ago

Given that literally nobody has ever needed, nor will they ever need, to talk about file sizes in millibits, there is no ambiguity involved.

arm• 7 years ago

Even though it’s unlikely anyone will think it’s referring to millibits, there’s still a decent chance some will assume Mb (Megabits) due to the lowercase 'b' instead of the intended MB (Megabytes).

I wonder what the transmission rate of information through genetic evolution is.

They have also made a talk about the the design process of the squoosh webapp: https://www.youtube.com/watch?v=ipNW6lJHVEs

Squoosh does not use best-in-class codecs [1]. Lossless PNG compression is 5-15% worse on average and lossy PNG compression (color quantization) is limited to PNG-8, which is not enough to maintain image quality. Lossy JPEG compression is only tuned for 4:2:0 chroma subsampling and causes blurring of fine details because trellis quantization is guided simply by the variance in DCT domain.

It's marketing hyperbole, no one really believes it's the absolute best-in-class.

The idea of this open source app from Google is to demonstrate a real world use case of porting legacy native code to the web via webassembly

C1sc0cat• 7 years ago

Exactly and if you need to quickly optimise some background JPEG to save 400Kb , because the designers / developers haven't optimised the flipping images.

The quality of a codec is easy to measure, and saying that it measures higher than others is not a hyperbole, but a lie. If you take something that's hard to compare, like developer effectiveness, and say he's the best, then it can be called a hyperbole.

I tested it yesterday, and it seems good enough for me.

I'd love to use ImageOptim, but I don't have a Mac, and the web plans are too expensive for optimizing maybe two images every three months.

Try hackintosh it’s great fun if you like OS X

wtmt• 7 years ago

You could try the online version of Imageoptim (with not as many options) here:

Didn’t this come out a couple of years ago? Is there a reason we are seeing it again now?

JPEG XT, JPEG XS, JPEG XL are all for completely different use cases and built with different technology. XT and XS are more mature standards, but less appealing for the internet use case than XL.

How does it compare to Squash -- other than being browser based?

pornel• 7 years ago

It has more tools and a GUI.

Squash is in the AppStore, so it can't contain any GPL-licensed compressors.

The_rationalist• 7 years ago

I wonder how much this will be obscoleted by JPEG XL.

theandrewbailey• 7 years ago

or AVIF.

JyrkiAlakuijala2• 7 years ago

JPEG XL reference codec includes a slower encoding mode for high density photography compression (iterating with butteraugli guidance like in guetzli). Of course there will always be some room for external optimizers, just I'd expect the gains to be smaller.

ocdtrekkie• 7 years ago

I usually use TinyPNG, but its not open source, and does send the images server-side, so shouldn't be used for sensitive files.

For some actual thing which you can use in your projects to automatically optimise images, check this:

I really like the UI design and PWA hints to add this to your mobile. Great work.
