The text discusses the modern alternatives to the aging JPEG image format for web use by comparing WebP, AVIF, and HEIC. WebP, developed by Google, offers decent compression with broad browser support, making it a safe choice. AVIF, based on the AV1 video codec, boasts superior compression, significantly reducing file sizes, but has slower encoding and requires a WebP fallback for older browsers. HEIC, Apple's format, provides strong compression and integration within the Apple ecosystem, but lacks broad browser support outside of Safari. The author recommends using AVIF with a WebP fallback for web images due to its excellent compression. Converting HEIC files to web-friendly formats is advised for sharing outside the Apple ecosystem. The article provides compression comparisons and conversion time benchmarks for each format. The text concludes with recommendations for various use cases, including e-commerce and archival purposes. Several methods, like command line tools and online converters, are presented for image conversion. The overall sentiment is that JPEG is outdated, with modern formats offering better compression and features.
