iOS app submission
App Store Connect rejects builds missing any required icon size. Generate the full set once, drop into Xcode's Assets.xcassets, never think about it again.
App Icon Generator
Upload one image and get all required icon sizes for iOS, Android, and Web — including favicon.ico. Everything runs in your browser.
We recommend a 1024×1024 pixel PNG. The tool will scale it down to all required sizes. Larger source images produce better quality icons.
iOS: 20, 29, 40, 58, 60, 76, 80, 87, 120, 152, 167, 180, and 1024px. Android: 48 (mdpi), 72 (hdpi), 96 (xhdpi), 144 (xxhdpi), 192 (xxxhdpi), and 512 (Play Store). Web: 16, 32, 150, 180, 192, 512px PNGs plus favicon.ico.

Why App Icon Generator?
One image in, every icon out — all sizes, all platforms, one click.
All sizes, all platforms
Generates every icon size needed for iOS (including 1024×1024 App Store), Android (all mipmap densities), and Web (favicons, apple-touch-icon, og-image).
Xcode-ready
iOS icons come with a proper Contents.json — drag the AppIcon.appiconset folder directly into your Xcode project.
Privacy by design
All resizing happens in your browser using HTML Canvas. Your images are never uploaded to any server.
One-click ZIP download
All icons neatly organized in folders (iOS, Android, Web) inside a single ZIP file. Ready to use.
25 languages
Interface available in 25 languages with automatic browser detection. RTL support for Arabic, Persian and Urdu.
Completely
No limits, no watermark, no sign-up. Use it as many times as you need.
How the app icon generator works
From one source image to all 30+ required sizes — in your browser, in a minute.
-
1
Drop a 1024 × 1024 source
Apple, Google, and the web all accept icons up to 1024 × 1024. Drop a square PNG (transparent background recommended for some platforms, solid for others — both work). We accept JPG too but PNG with transparency gives the most flexibility.
-
2
Generate every size in parallel
iOS needs ~18 sizes (App Store, home screen at 2x/3x, settings, spotlight). Android needs ~5 mipmap densities (mdpi → xxxhdpi). Web needs favicons (16, 32), apple-touch-icon (180), Chrome (192, 512), and a manifest. Each size is downscaled with high-quality bicubic resampling using OffscreenCanvas.

Live preview shows iOS / Android / Web
See the generated icon as it would appear on iOS home screen, Android launcher, and a browser tab — all rendered live. Spot rendering issues (text too small to read at small sizes, lost details after resize) before exporting.
-
4
Download as a single ZIP
Output is a structured ZIP with iOS folder (ready for Xcode Asset Catalog), Android folder (mipmap-mdpi through mipmap-xxxhdpi), and Web folder (favicon.ico, manifest.json). Drag the appropriate folder into your project.
Who needs every size
Icon generation isn't optional for most platforms — here's why.
Android Play Store
Google requires a 512 × 512 hi-res icon plus mipmap densities for the launcher. iKit produces both formats from one source — no need to render the same artwork five times manually.
Progressive Web App
PWAs need a manifest with multiple icon sizes (192, 512 minimum). iKit generates the manifest.json snippet for you, ready to paste into your existing manifest.
Refreshing existing apps
Brand redesign? Drop the new logo, get a complete new icon set in 30 seconds. Compare with the old set in the live preview before committing.
Why local generation matters for brands
App icons are often unreleased brand work — a redesign, a new product, a confidential client logo. Uploading them to a server-side generator means a third party sees the asset before launch, with all the leak risk that implies. iKit generates everything in the browser using OffscreenCanvas, so your unreleased brand never leaves your machine.
- Source PNG and all 30+ generated sizes stay in your browser.
- ZIP packaged client-side — no server file to be cached.
- Suitable for confidential and pre-launch brand assets.

Frequently Asked Questions
What image size should I use?
We recommend a 1024×1024 pixel PNG. The tool will scale it down to all required sizes. Larger source images produce better quality icons.
What icon sizes are generated?
iOS: 20, 29, 40, 58, 60, 76, 80, 87, 120, 152, 167, 180, and 1024px. Android: 48 (mdpi), 72 (hdpi), 96 (xhdpi), 144 (xxhdpi), 192 (xxxhdpi), and 512 (Play Store). Web: 16, 32, 150, 180, 192, 512px PNGs plus favicon.ico.
Is my image uploaded anywhere?
No. All image resizing uses your browser's Canvas API. Your image never leaves your device.
Does it include favicon.ico?
Yes. The Web icons include a multi-size favicon.ico (16×16 and 32×32), plus individual PNG favicons.
Can I use a transparent background?
Yes. Check the 'Transparent' option. Note that iOS App Store icons require a solid background — Apple will reject transparent icons.
