Hello, wouldn't webp be bit better then png? I converted it to webp (with quality 100%) and packed both in packages 7Zip. Pics with Webp weigh less by 140 MB.
While Ren'py supports webp, tyranobuilder's FAQ page recommends the use of jpg, png or gif files. So, I thought I'd just leave it as PNG.
But you are correct, I should provide the packs in webp format. Starting from my next asset pack, I'll publish it in both png and webp format.
Thank you :)
