Solved PNG to WEBP (with transparent background)

[BadLuck]

Hello,

is there a way to use "Bulk conversion" to export PNGs to WEBP while keeping the transparent background?
I've exported JPGs and they are great but with some PNGs the background was changed from transparent to black

IrfanView does not support export of transparency for the WebP format.

IrfanView does not really support transparency. It cannot copy it over from the input, only generate an approximation. Do not rely on it for any format.

You can use XnView for saving WebP. The program has a similar feel.

If you are familiar with command line and batch files, you may use libwebp utilities from Google. They provide much more options for creating webp files.
