Do you want a static binary (ie. one that doesn't dynamically link in anything, not even `libc`) or a binary that doesn't dynamically link in `libpng`? If latter, then this...

We will soon publish a more detailed comparison that takes mozjpeg and libjpeg into account. Note that comparing two JPEG encoders is more complicated than it might at first appear,...

@magicgoose Note that mozjpeg encodes with YUV420 by default. When you ask mozjpeg to encode with YUV444, the produced image is ~45% larger: ``` $ ~/mozjpeg/cjpeg -quality 85 bees.png >...

@vinhlh Size comparisons make sense between images equivalent in quality. ~~What method did you use to ensure that quality was the same on both sides?~~ I've taken a look at...

@jmespadero Small correction: it's 125 bytes per pixel, not KB per pixel.

Thanks for this PR; it's quite large, not very trivial, and I don't speak Chinese, so it'll take me some more time to look through it. @crazyks @pornel Please pay...

We aim to produce images that will not surprisingly not display on some browsers, when a JPEG produced by more "conventional" tools would. This sadly rules out arithmetically coded JPEGs:...

The effort required to support arithmetically encoded JPEGs in a browser seems to be of the same sort of magnitude as effort required to get something like [Lepton](https://github.com/dropbox/lepton) supported. Lepton...

Thanks for trying out Guetzli. Could you post the files you've tried and the sequences of commands you've used?

Guetzli doesn't produce png files. The `compress_by_guetzli.png` is actually a JPEG file and is identical to `compress_by_guetzli.jpg` It's true that the png files are smaller than the jpg files produced...
