All the files in there are lossless webp. That is why I thought you use lossless webp.
And I did not say you use png. I used the screenshot as a reference file for compression comparison between lossless webp and lossy webp. The difference was 518kB (png) 353kB (lossless webp) 49kB (lossy webp in setting 90/6). And I found it odd, that the setting 90 was needed for that screenshot. Webp is usually better at this.
There are obviously translations issues here. English is not my native language, neither is it yours. If you think I suggested you should use png, please read my post again. If you still think so, use a translator page.
