What format should I use?

WebP for web (smallest size), PNG for transparency, JPEG for photos. WebP is 25-35% smaller than JPEG.

Does conversion affect quality?

Converting to lossy formats (JPEG) may reduce quality. PNG to PNG or WebP lossless preserves quality.

WebP is a modern image format by Google. It offers better compression than JPEG and PNG with similar quality.

Which browsers support WebP?

All modern browsers support WebP: Chrome, Firefox, Safari, Edge. Only IE11 doesn't support it.
