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.

Google Chrome Is Already Preparing To Deprecate JPEG-XL (~3x smaller than JPEG, HDR, lossless, alpha, progressive, recompression, animations)
That's not necessarily the case with the jpeg2png decoder, but it's been a while since I used it, and I'm not able to test right now. The PNG files will be smaller than with the usual JPEG decoding process, at least.

Losslessly Optimising Images
This tool optimises blocky JPEGs for a better viewing pleasure: https://github.com/victorvde/jpeg2png
> jpeg2png finds the smoothest possible picture that encodes to the given JPEG file.

screen capture/snapshot utility with image optimization support/configurability
I have had good experiences with https://github.com/shssoichiro/oxipng . Although, I suspect this wouldn't give you nearly enough space savings as jpg.

Exported png image with color-to-alpha edit is huge
If you do want the file as a PNG (for transparency and a common format that's well supported), but don't want it so huge, consider something like oxipng. https://github.com/shssoichiro/oxipng

Losslessly Optimising Images
I wonder how `pngcrush` compares to `oxipng` (https://github.com/shssoichiro/oxipng).
Personally, I use `oxipng` if I want lossless compression. However, most of the time, I use `pngquant` instead, since it gives significant size reduction even at `99%` (I can't even distinguish between the original and reduced image).
pngquant --quality=99 --ext=.png --force file.png

Adobe plans to make Photoshop on the web free to everyone
Depending on your workflow it might make sense to export PNGs directly from Affinity and then reduce their size with a utility like Oxipng, which uses all your cores to find the best algorithm for each particular image.

Help processing massive videos (16k resolution)
Assuming your frames are PNG files, you could use a lossless optimizer like optipng to try if their size can be reduced. I prefer oxipng, which is faster and multithreaded, and seems to have more active development.

(Urgent) Best Image Compressor Sites That Barely Compress?
Not sure what extensions of images you use, but if they’re PNG you could use oxipng: https://github.com/shssoichiro/oxipng
What are some alternatives?
ImageOptim-CLI - Make optimisation of images part of your automated build process
squoosh - Make images smaller using best-in-class codecs, right in the browser.
shrivel - Command line wrapper utility to shrink a path of images for web based on external tools.
