❓ FAQ: PNG to WebP Conversion

Is converting PNG to WebP worth it for SEO?

Absolutely. WebP provides superior compression (up to 95% smaller files) while keeping alpha transparency. This directly fixes the "Serve images in next-gen formats" warning in Google Lighthouse, improving PageSpeed scores, user experience, and search rankings.

Will I lose transparency converting PNG to WebP?

No! Our converter specifically supports the alpha channel, ensuring that your transparent PNG backgrounds stay transparent while the file size drops dramatically. WebP fully supports transparency just like PNG.
