Frequently Asked Questions

Does WebP support transparency like PNG?

Yes. WebP supports an alpha channel for transparency in both lossy and lossless modes. This makes it an excellent replacement for PNG in web use cases where transparency is needed, with significantly smaller file sizes.

Should I use lossy or lossless WebP?

Use lossless WebP for graphics, logos, screenshots, and images where pixel-perfect quality matters. Use lossy WebP for photographs and complex images where minor quality reduction is acceptable in exchange for much smaller file sizes.

How much smaller will my PNG be as WebP?

Lossless WebP is typically 26% smaller than PNG. Lossy WebP can be 60-80% smaller while maintaining acceptable visual quality. Exact savings depend on the image content — simple graphics with large flat color areas see the biggest reductions.
