ToolBox Image — WebP vs AVIF: qual formato de nova geração economiza mais espaço?

Tanto WebP quanto AVIF prometem melhor compressão que JPEG. Nós os colocamos frente a frente em imagens reais para ver qual formato entrega os menores arquivos sem sacrificar a qualidade.

Two formats — WebP and AVIF — both promise significantly better compression than JPEG. But which one should you actually use?

File size comparison

At equivalent visual quality, AVIF consistently produces smaller files than WebP. Our tests on a 4000 × 2250 photograph showed:

FormatFile sizeSavings vs JPEG
JPEG (quality 80)1.8 MB
WebP (quality 80)1.2 MB33%
AVIF (quality 80)720 KB60%

AVIF is roughly 40% smaller than WebP on photographic content.

Browser support

WebP has wider support — roughly 97% of global browsers versus 92% for AVIF. Both are supported in Chrome, Firefox, Safari, and Edge.

Encoding speed

WebP encodes 3-5 times faster than AVIF at the same quality setting. Our compressor handles this by processing images in parallel across all CPU cores.

Which should you choose?

Use WebP as your baseline and AVIF where you need maximum savings. WebP is faster to encode, has wider browser support, and still saves 25-35% compared to JPEG. AVIF is worth the extra encoding time for photographic content where every kilobyte matters.
