View source for Use WebP as default freeCap image type

%%
// image type:
// possible values: 'avif', 'gif', 'jpg', 'png', 'webp'
// jpg doesn't support transparency (transparent bg option ends up white)
// avif and webp may not be supported by your GD Lib.
$output = 'webp';

I'm tempted to set **WebP** as the new default image type for Captcha. Are there stacks with GD Lib without WebP support in 2025?

if (gd_info()['WebP Support'])
{
