About the formats
PNG is a lossless image format with transparency. It is ideal for screenshots, logos and graphics, but photos saved as PNG are much larger than JPG.
WebP is Google’s web image format. Browsers save images as WebP more and more often, but many editors, slide tools and older apps still can’t open it.
