Frequently Asked Questions

Does WebP support PNG transparency?

Yes, WebP supports full alpha channel transparency, just like PNG. Your transparent backgrounds and semi-transparent elements will be preserved perfectly.

When should I use WebP instead of PNG?

Use WebP for any image served on the web: icons, logos, UI elements, illustrations. Keep PNG only for source files or when software compatibility requires it.

What quality setting should I use for PNG to WebP?

For lossless-quality results, use quality 90–100. For a balance between size and quality (lossy), quality 75–85 is generally a good starting point.
