PNG to AVIF: maximum compression for web delivery
AVIF uses the AV1 codec's intra-frame compression which employs prediction-based encoding, transform coding, and in-loop filtering to achieve 50% smaller files than JPG and 20-30% smaller than WebP. Converting a lossless PNG to AVIF applies lossy AV1 compression by default, producing dramatically smaller files. AVIF preserves alpha transparency, supports wide color gamut (Display P3, Rec. 2020), and handles HDR content — capabilities PNG matches only in file size terms.
Convert PNG to AVIF for the smallest possible web images with the best visual quality per byte. AVIF is ideal for hero images, product photography, and media-heavy pages where every kilobyte of bandwidth matters. Check your audience's browser support and serve PNG or WebP as a fallback using the HTML picture element.
