About This Conversion
What is WebP?
WebP is a modern image format developed by Google that provides superior compression for images on the web. It supports both lossy and lossless compression, alpha channel transparency, and animation. WebP files are typically 25-34% smaller than equivalent JPG files at the same perceptual quality.
What is AVIF?
AVIF (AV1 Image File Format) is a cutting-edge image format based on the AV1 video codec. It delivers superior compression efficiency compared to WebP, supporting HDR, wide color gamut, 10/12-bit color depth, alpha transparency, and animation. AVIF typically achieves 10-20% smaller files than WebP at the same visual quality.
