Glyphus - Drop one icon, get every App Store size — free

by•
Glyphus turns a single 1024×1024 icon into a complete, Xcode-ready icon set — every iOS, iPad, macOS, and watchOS size, Android mipmaps, and the Play Store 512 — in one zip. No account, no API key, nothing stored. Deterministic sizing (no AI guessing pixels), plus an MCP server and CLI so your coding agent can generate icons directly.

Hey PH 👋 I built Glyphus because resizing one app icon into 30+ files, every release, for every platform, got old fast. Drop a 1024 square in, get a zip with every required size out — Contents.json already written, Android mipmaps already sorted. A few things I care about that shaped it: No AI in the resize path. Every output size comes from an explicit size table in code, not a model. Deterministic in, deterministic out. No account needed. One request, one zip, nothing stored server-side. Built for agents too. The same API backs an MCP server and a CLI, so Claude Code / Cursor / a script can call generate_icon directly instead of going through the browser. Currently building a native macOS app for App Store screenshot generation as the next piece — waitlist is open on the site if that's useful to you. Would love feedback, especially from anyone who ships to both App Store and Play Store regularly.
