About the App Icon Sizer Tool
The App Icon Sizer takes a single source image and resizes it into every icon size you need for iOS, Android, macOS, and the web. Everything runs locally in your browser using the Canvas API, so your artwork is never uploaded to a server.
Shipping an app usually means exporting dozens of icon sizes by hand to satisfy each platform's requirements. This tool does that in one pass, then packages the results into platform-labeled folders you can drop straight into your project.
How to Use the App Icon Sizer
Upload your icon
Drop or select a square image, at least 1024 × 1024px, for the sharpest results.
Choose platforms
Pick any combination of iOS, Android, macOS, and Web/PWA presets.
Generate icons
Every size is rendered locally in your browser using the Canvas API.
Download
Grab a single icon, or download the whole set as one organized ZIP file.
Common Use Cases
App Store & Play Store Submission: Generate every required iOS and Android icon size before uploading your build.
macOS & Electron Apps: Produce the full 16 to 1024px icon set that macOS app bundles expect.
PWA Manifest Icons: Create favicon and manifest icon sizes for your web app manifest in one pass.
Rebranding an Existing App: Swap in a new icon and regenerate every platform size instead of re-exporting by hand.
Design Handoff to a Mobile Team: Hand developers a ready-made, organized icon set instead of a single master file.
Cross-Platform Launches: Keep icon sets visually consistent when shipping the same app to iOS, Android, and web.
