oxipng VS PhotoGIMP

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.

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

oxipng, pngquant and svgcleaner — optimizing 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

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.

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.

Not sure what extensions of images you use, but if they’re PNG you could use oxipng: https://github.com/shssoichiro/oxipng

I used to use PhotoShop heavily and still have a lot of the UI muscle-memorized. I switched to GIMP + https://github.com/Diolinux/PhotoGIMP and found it mostly fits my needs for basic image editing.

There's also photoGimp:

But it's interesting if we can get FOSS Gui toolkits that allow for different approaches to menu/toolbar/discovery where the user can easily adjust and select how things should work - like readline Emacs/vi selection on steroids for Gui.

There is this project that might help you:

I doubt it, code needs to be maintained , even if you will get stuck on old libraries you could miss out on features and improvement, of course if the changes are small and it's more like a patchset (something like photogimp) , that might be more feasible.

I don't like gimp at all, but you can still try PhotoGimp.

did you try PhotoGIMP?
