Squoosh mentions (201)

  • Firefox intent to ship: JPEG XL
    It often comes down to compat, and developer requests. Personally I find in-browser encoding for images inadequate, because it doesn't expose enough options. When we built https://squoosh.app/, we exposed the browser encoders for completeness, but they're pretty bad compared to the wasm codecs. - Source: Hacker News / 16 days ago
  • Can you build a recognizable World Map in under 500 bytes?
    Its a fun challenge. I used https://squoosh.app to make a pretty good one. Mostly just a resize and then OxiPNG for compression. Managed a 124x62 black/white image. OP has a resolution of 195x53, so I had very similar, but slightly worse I think? Mostly a different aspect ratio + map projection I think. Playing with Squoosh.app is very fun, and you can very easily see how the jump from 500b to ~1.5kb turns a map... - Source: Hacker News / 2 months ago
  • Speed Up Your WordPress Site in 30 Minutes: A No-Plugin Performance Guide
    Use a free tool like Squoosh (by Google) to batch convert your existing images to WebP. - Source: dev.to / 4 months ago
  • Free Browser Tools for Developers Who Make Content
    Every image goes through Squoosh before it lands in any repo I own. Drag the file in, pick WebP or AVIF, drag the quality slider until the preview still looks clean, download. The size reduction is usually 60–80% with no visible quality loss. It runs entirely locally in your browser — nothing is uploaded anywhere. For a performance-conscious developer this matters. Best for: Pre-commit image optimisation, blog... - Source: dev.to / 5 months ago
  • Rust WASM vs TypeScript Performance: Why the 'Faster' Language Lost by 25% [2026]
    The Squoosh image compression app from Google is a great example. It runs codecs like MozJPEG and WebP entirely in WASM, processing large image buffers with minimal boundary crossings. Near-native compression performance, right in the browser. - Source: dev.to / 6 months ago
