What is WebP?

WebP is a modern image format introduced by Google in 2010 for the web. It supports lossy and lossless compression, transparency (alpha), and animation.

Comparison with other formats

Typical file size savings (similar quality)

  • Lossy WebP is 25–34% smaller than JPEG
  • Lossless WebP is about 26% smaller than PNG
  • Animated WebP is about 64% smaller than GIF

Why can WebP be smaller?

  1. VP8-based coding: lossy WebP is based on VP8 video codec techniques with more advanced prediction and transforms.
  2. Better intra prediction: predicts blocks from neighboring pixels to reduce redundancy.
  3. Adaptive quantization: dynamically allocates bits to preserve details where needed.
  4. Entropy coding improvements: uses more efficient coding techniques to reduce size.
  5. Lossless innovations: combines predictors and transforms (e.g., color transform) for better lossless compression.

FAQ

Why does the converted WebP look static?

  • Common reason: Windows File Explorer previews, some image viewers, and some platforms/IM apps show only the first frame (they do not play Animated WebP).
  • Solution: open the downloaded .webp in Chrome/Edge/Firefox; it should animate.
