FAQ

Frequently Asked Questions

Why convert PNG to WebP?

PNGs are often large, especially with transparency. WebP cuts 60–80% off the size at the same quality and transparency — a big win for performance.

Does WebP support transparency?

Yes. WebP keeps the alpha channel like PNG, so logos, icons, and graphics stay transparent.

When should I NOT convert PNG to WebP?

If software or a CMS requires PNG, or you'll keep editing the file, keep the PNG. For web display, WebP is almost always better.
