## Questions

### How much smaller is WebP?

Typically 25 to 35% smaller than a comparable JPEG and far smaller than a PNG for photographic content, at visually equivalent quality.

### Is WebP supported everywhere?

Every current browser supports it, including Safari since version 14. The only holdouts are very old clients, and a picture element with a JPEG fallback covers those.

### Does WebP keep transparency?

Yes, unlike JPEG. That makes it the best replacement for a PNG logo - transparency preserved, usually a fraction of the size.

### Should I use AVIF instead?

AVIF compresses better again but encodes slowly and browser support is thinner. WebP is the pragmatic default; ship AVIF as an extra source if you can generate it in your build.

### Should I still keep a PNG fallback?

No. Every browser released since 2020 supports WebP, including Safari 14 and later. A fallback is now dead weight in your markup.

### Does converting to WebP lose transparency?

No. WebP supports a full alpha channel, which is what makes it a real replacement for PNG rather than for JPEG only.

### Is WebP lossy or lossless?

It supports both. This converter uses lossy encoding with a quality slider, which is where the large savings come from. Lossless WebP still beats PNG by about 25%.

### Will WebP hurt my image SEO?

No. Google Images indexes WebP normally, and the format is Google's own. What matters is alt text, filename and that the image loads fast.
