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 e…

This describes the problem more or less but it does not give a single working solution. Image optimization now includes videos, scaling, format and color conversion, and simply com…

The website assets are optimized in a rather strange way. The total page weight of ~20MB is huge for mobile. The images are heavily compressed using WebP lossy with quite noticeabl…

I have been making Optimage which is currently the only tool that can automatically optimize images without ruining visual quality [1]. It is also the new state of the art in lossl…

I specifically meant automatic lossy compression with predictable visual quality. If ImageOptim could actually achieve it (automatically), that would save me and others an awful lo…

It's alright. There's a 77 KB spinner.gif that can be reduced by half.

Well, the problem is the uncanny valley between native and its imitation.

Qt does not use native widgets only simulates them.

Yes, some of the source images are tagged with ICC color profiles. It looks like Firefox still does not treat untagged images as sRGB and the difference on wide-gamut monitors may …

Why? There's an extensive benchmark [1], also seen on the homepage, that proves it is the first tool that does not break images like other state-of-the-art tools, i.e. fits the sub…

I plan to release a cross-platform CLI tool first. The core tool already works under *nix. But there's still a good portion of business logic in the app. The work on a cross-platfo…

I find the irony in more prosaic details like a 2.1MB image [1] to show the new UI of "Secure, Fast & Private Web Browser" (for comparison optimized PNG8 is 351KB [2] and JPEG is 3…

JPEG is not a good choice for UI/typography screenshots. There are ~1MB of JPEGs at quality 50 on the page. By using PNG8 not only you can halve that size but also preserve origina…

WebP lossy and WebP lossless often get mixed up. They are substantially different. While the former is mostly just outdated VP8 4:2:0, it is fast and more pleasing to the eye than …

You will get better results by swapping the two. Pngquant stops at color quantization. Also, most of those savings came from near-optimal Deflate compression.

Nice to see you're using the same animation technique [1]. MP4 could not possibly provide this level of quality/size (~150KB per animation). Pngcrush is rather limiting though. I c…

Why is it not a browser feature? Transferred 175MB just to measure the speed. Good it does not do it at 3G speeds. There are also 156KB of images waiting to be compressed to one th…
