Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

It's the future – you can stop using JPEGs
It would be nice if the author would add mozjpeg[1] to the comparison. At certain sizes, it can produce smaller sizes than WebP, and because it is still a jpeg, it has a much better compatibility story, which the author alluded to.

Random Code Inspiration Volume 2
image-shrinker is a simple, easy to use open source tool for shrinking images. Under the hood it uses pngquant, mozjpg, SVGO, and gifsicle. You can also install these tools individually if you need to compress some images. I often use pngquantafter exporting PNGs for web projects from Figma or similar tools. I literally run it like this:

JPEG XL: How It Started, How It’s Going
> MozJPEG is a patch for libjpeg-turbo. Please send pull requests to libjpeg-turbo if the changes aren't specific to newly-added MozJPEG-only compression code.

Why there may never be a libjpeg-turbo 3.1
FWIW, Mozilla has been maintaining their own fork for quite a while now[1]
AFAIK most Linux Distros have been using libjpeg-turbo as a drop-in replacement for libjpeg, after some drama in ~2010 where libjpeg came under new management, decided to break ABI/API several times over and add incompatible, non-standard format extensions[2].

Are all JPEG compression implementations the same?
No.
See https://github.com/mozilla/mozjpeg
Also, there is a fairly big problem with JPG that the ‘quality’ setting is not calibrated. That is you might look at one image and think it looks fine (which is subjective, depends on what you want to use the image for…) with a quality of 60%, but then you compress a million images at that rate, delete the originals, then you find that many of them look really awful. Not only that but there are images you could have compressed more and still been happy with the output.
If you are publishing images for the web consider using WebP which is consistently better, well supported now, and has a calibrated quality knob.

reduce the size of a bunch of jpg
https://github.com/mozilla/mozjpeg's cjpeg tool is the command line version of the mozjpeg library, itself a fork of libjpeg-turbo. Mozjpeg performs lossless JPEG optimization. There are plenty of others out there.
-
Lossy Image Compression with Dithering
Use the Mozilla JPEG Encoder, which implements several tricks for smaller file size / better visual quality. The result is still JPEG standard compatible that other software can decode.

Fighting JPEG Color Banding
Guetzli was already mentioned and roughly does what you are talking about.
MozJPEG [1] includes several quantization tables that are optimized for different contexts (see the quant-table flag and source code for specific tables[2]), and the default quantization table has been optimized to outperform the recommended quantization tables in the original JPEG spec (Annex K).
It's also worth noting that MozJPEG uses Trellis quantization [3] to help improve quality without a per-image brute force quantization table search. Basically rather than determining an optimal quantization table for the image, it minimizes rate distortion on a per-block level by tuning the quantized coefficients.

FFmpeg now supports JPEG XL
They're still being used. A newer, optimized JPEG encoder, mozJPEG[0], seems to use progressive encoding by default. I suspect with faster internet speeds, most images download and decode so fast that the cool 'enhance' animation doesn't happen anymore.

Building an online image compressor
One of the most complete image compressor out there, squoosh.app by Google, uses web assembly for decoding/encoding images and it works pretty well.

Power Consumption of JPEG, WebP, and AVIF

Having a quick look at squoosh, it uses lossy compression of webp by default.

What makes a page rank well?
Size images appropriately (https://squoosh.app/ can be used for this). Ideally, the size of the image should be kept below 100 KB.

my live site keeps jumping back to the top of the page while I'm using it
if your images a large file size, remove them from the page, reduce file size, and place new reduced file size images in their place - publish the site to bring the new pics live - clear your cache - go the page and test it (good tool to reduce image file size is Google Squoosh - https://squoosh.app/ )

Can anyone recommend any decent plugins that let me adjust jpg quality on export for web,
I'm just exporting normally from Figma, but then using squoosh.app (browser based) to adjust quality/compression and even for making sure png files are optimized for prod.

Hey I see your friend made a clan, but this guy found a workaround here if you still need it. I just used https://squoosh.app/ to basically save a new copy of the image and that worked
