Each image is converted to WebP at its original size.
Widths larger than the original are skipped. Upscaling only adds bytes.
This browser can't encode AVIF yet. Your visitors can still view AVIF files; try Chrome or Safari to create them.

Why convert PNG to WebP
PNG is lossless, which makes it large. A photo saved as PNG can be five or ten times bigger than it needs to be, and WebP brings it down to a sensible size. Unlike JPEG, WebP supports transparency, so logos and cut-out product shots keep their transparent background.
The default quality here is 85, a little higher than for photos. Screenshots and images with text or sharp edges look best at 90 or above, so raise the quality if you see soft edges around text.
Every current browser displays WebP. For several sizes and srcset markup, use the full responsive image converter.
Questions
Is the transparency kept?
Yes. Transparent and partly transparent areas carry over into the WebP file.
Should every PNG become a WebP?
Not always. Simple logos and icons are usually smaller and sharper as SVG. For screenshots, compare the WebP at a high quality with the original before you switch.
