Ottimizzazione delle immagini web nel 2026: WebP, AVIF e oltre
I formati di immagine moderni offrono pagine più veloci. Impara quando usarli WebP, AVIF, JPG e PNG, e come convertirli gratuitamente.
Page speed directly impacts SEO rankings and user engagement. Images are typically the largest assets on a web page, making image optimization one of the highest-impact performance improvements you can make.
WebP, developed by Google, has become the de facto standard for web images in 2026. It offers 25-35% smaller files than JPG at comparable quality, supports transparency (like PNG), and animation (like GIF). Browser support is now universal.
AVIF pushes the boundary further with 30-50% better compression than WebP. Derived from the AV1 video codec, AVIF delivers stunning quality at tiny file sizes. Browser support has reached 95%+ with Safari joining Chrome and Firefox.
Choosing the right format depends on your needs: AVIF for maximum compression on modern browsers, WebP as a broadly compatible modern format, JPG for legacy fallback, and PNG only when lossless quality with transparency is essential. SVG remains the best choice for icons and logos.
ConvertCraft lets you convert between all these formats instantly in your browser. Drop any image — JPG, PNG, HEIC, WebP, AVIF, BMP, TIFF — and convert to your target format with quality control. Batch processing handles entire image libraries at once.
