  "account": "The format debate for web images has evolved significantly, with choices now including JPEG, PNG, WebP, and AVIF. In 2026, these formats offer different qualities and compatibility levels. JPEG, the universal lossy format, remains the default for photos, easily supported across all browsers. However, it struggles with sharp edges, transparency, and large files.\n\nPNG is the go-to for sharp edges, transparency, and lossless compression. It's ideal for UI elements, logos, and diagrams but can result in larger file sizes compared to WebP or AVIF.\n\nWebP, a versatile format, offers both lossy and lossless options, along with alpha channels and animation. It is typically smaller than JPEG and often smaller than PNG, supporting wide browser compatibility since 2025. AVIF, another contender, provides even smaller file sizes at comparable visual quality, but lacks progressive rendering and incurs heavier encoding.\n\nFor photographs, AVIF should be the primary choice, followed by WebP, with JPEG as a fallback. Sharp graphics and UI elements with transparency should use lossless WebP or PNG, with PNG as a fallback. JPEG remains crucial for items needing email compatibility or stability.\n\nWhile browser support has significantly improved, challenges persist with older iOS Safari, Android WebViews, Internet Explorer, and non-browser services like email clients. The HTML picture element, widely supported, allows for progressive format improvements. It's essential to encode files from the master source and keep consistent dimensions to avoid fallback issues. MIME type should be correctly set for each format.\n\nFollowing four rules—encoding derivatives from the master, maintaining consistent dimensions, using the correct MIME type, and confirming the actual file fetched—can prevent common pitfalls. JPEG remains the most universally accepted format for web delivery.",
  "summary": "The format decision used to be simple: JPEG for photos, PNG for anything with sharp edges or transparency. In 2026 you also have WebP and AVIF, both widely supported, both usually smaller, and both still the wrong choice in more situations than the blog posts admit. I built jpg.now because I kept doing the same conversions for client sites, CMS uploads, and \"please send a JPG\" requests, and I am…",
