Answers to common questions regarding WebP image conversion, alpha channels, and matte colors.
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. It supports alpha channel transparency (like PNG) but with much smaller file sizes. However, some older systems or editors may require JPEG or PNG formats.
To keep transparent backgrounds, select PNG as the output format. PNG fully supports alpha transparency. If you choose JPEG, transparent areas must be flattened, and they will be filled with your selected background matte color.
