Keep transparency in a web asset

Choose transparent background to preserve a PNG alpha channel when exporting WebP. With padding enabled, the extra canvas area is transparent too.

When to use it

For flat graphics, compare the output against the original. This converter uses browser quality-based WebP export and does not expose a lossless WebP switch.
