Free Online Image OptimizerConvert PNG to WebP
PNG is honest but heavy, and it is what your screenshot tool and your designer both hand you. Converting PNG to WebP keeps the same picture, keeps the transparent background, and very often shrinks it to a fraction of the size.

Screenshots, logos, exported artwork, anything with a transparent background.
WebP carries an alpha channel, so a logo that was transparent stays transparent.

Step by step, with screenshots: How to convert PNG to WebP and keep the transparency
Yes. WebP supports transparency properly, which is the main reason it is the right destination for a PNG. The one thing to watch is that JPEG does not — if you also tick JPEG in the formats list, that version will come back with the transparency filled in.
Usually much more dramatic than the JPG case. PNG stores every pixel exactly, so a screenshot or a flat-colour logo often drops by seventy per cent or more with no visible difference at all. Photographs saved as PNG shrink even further, because PNG was the wrong format for them to begin with.
For a screenshot or a logo, in practice nothing you can see. If you need a guarantee of pixel-for-pixel identity — a technical diagram going into print, an image you will edit again later — keep the PNG as your master and use the WebP for the web.
AVIF is smaller again and also carries transparency, but a few older browsers cannot read it. Tick both and you get both, which is what the responsive image generator is for.
