WebP Alpha Support

WebP supports full 8-bit alpha channel transparency, just like PNG. But WebP lossless with alpha is typically 20-30% smaller than equivalent PNG.

When to Use Transparent WebP

  • Logos and brand marks
  • Product cutouts
  • Overlay graphics
  • Icons with transparency

    • Conversion

    Convert PNG with transparency to WebP lossless to preserve the alpha channel. Our converter automatically detects and preserves transparency.

    Browser Fallback

    Use the element to serve WebP with PNG fallback: ``html Logo ``
