Frequently asked questions

Is WebP better than JPG?

WebP typically produces 25-35% smaller files than JPG at the same visual quality. It's supported by all modern browsers (Chrome, Firefox, Safari, Edge) and is the recommended format for web images.

Does WebP support transparency?

Yes. WebP supports alpha channel (transparency) like PNG but with much smaller file sizes. This is why WebP is increasingly replacing PNG for web graphics.

Why compress WebP further?

While WebP is already compressed, our optimizer can squeeze out an additional 10-30% reduction by removing unnecessary metadata, optimizing color tables, and using smarter encoding.
