Tips and questions

Which format should I pick?

JPEG for photos that must open anywhere. PNG for graphics with see-through parts. WebP for small web images. AVIF for the smallest files.

What quality should I use?

About 75 to 85% looks the same as the original. And the file is much smaller.

Will PNG to JPG keep my see-through background?

No. JPEG cannot be see-through. Use PNG or WebP to keep it.
