Guides, comparisons, and reference charts on app icons, favicons, and icon design — from the team building IconsCove.
How to design and ship dark, tinted, and clear app icons for iOS and macOS, plus Android themed icons and the web. What each appearance keeps from your artwork, the exact files Xcode wants, and what the system does if you skip them.
How to set a favicon, icon, and apple-icon in the Next.js App Router, plus the override rules the docs don't state: metadata.icons removes your file conventions, and a static icon.png isn't served where you think.
The Android icon density table, the 108 / 72 / 66 dp geometry explained properly, and an honest answer to how many of those files a modern project still needs.
Since Android 16 QPR2 the system themes your app icon whether you ship a monochrome layer or not. What that changes, how to add the layer, and what the monochrome artwork should actually look like.
What Apple's layered app icons actually require in 2026, including the iOS 27 changes most guides miss: reduced translucency, automatic specular highlights, and the shimmer effect Apple removed.
A step-by-step way to find out why your favicon isn't showing: check the URL first, then the link tags, then the browser's separate favicon cache, then Google's recrawl schedule.
The favicon sizes and formats that actually matter in 2026: a modern .ico + SVG + 180×180 set, the HTML link tags, dark-mode SVG favicons, and Google's search favicon rules.
Every app icon size you need in 2026, from iOS and Android to favicon and PWA, in copy-paste tables sourced from Apple, Google, and the W3C manifest spec.
