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. Source: about 1 year ago

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. Source: over 1 year ago

Oxipng, pngquant and svgcleaner — optimizing images. Source: over 1 year ago

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

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. Source: about 2 years ago

While you aren't wrong... If you don't already have a membership, they do have temporary memberships (somewhere between 3 to 7 days of consecutive use, I forget exactly). Check them out https://eosfitness.com/. Source: about 2 years ago

You got me curious: googling it looks like https://eosfitness.com is 24 hours and has hot tubs. I'd call them tho, I wouldn't be surprised if the hot tubs are part of a pool area that isn't 24 hours or something like that. Source: over 2 years ago
