Which formats can I convert between?
PNG, JPG, and WebP are all supported as both source and target formats.
Does converting to JPG lose transparency?
Yes, JPG doesn't support transparency — converting a transparent PNG to JPG will fill the transparent areas with a solid background.
Why would I convert to WebP instead of JPG or PNG?
WebP typically produces a smaller file than JPG at similar visual quality, and unlike JPG it still supports transparency — a useful middle ground when file size matters but you also need an alpha channel.
