What size is the iOS App Store icon?

The App Store requires a 1024×1024 pixel icon. This is the highest quality version used for the store listing. Apple scales it for all other uses.

Can iOS app icons have transparency?

No. Apple explicitly requires that App Store icons and app icons have no transparency (no alpha channel). If your PNG has a transparent background, Apple will reject it. Use a solid background color instead.

Does Apple round the corners of my icon?

Yes. Apple applies a squircle (superellipse) corner rounding to all app icons automatically. You should not pre-round the corners yourself — supply a square icon and let Apple apply the mask.

What icon sizes does Xcode need?

Modern Xcode (15+) only requires the 1024×1024 App Store icon — it generates all other sizes automatically. However, older projects and some configurations still require all individual sizes.

Are my images uploaded to a server?

No. All processing happens entirely in your browser using the Canvas API. Your images never leave your device.

What image formats can I upload for iOS icon generation?

You can upload any PNG, JPEG, or WebP image. PNG is strongly recommended because it preserves quality without compression artifacts. JPEG and WebP will be converted to PNG on export.

iOS App Icon Generator — Generate All Sizes for App Store

Why Use This Tool?

iOS apps require icon files at many different pixel densities to support every iPhone and iPad model. While modern Xcode can auto-generate sizes from a single 1024×1024 source, older projects, CI pipelines, and some submission workflows still need all sizes pre-generated. This tool creates the complete set in seconds.

Privacy First — 100% Client-Side

Your images are processed entirely in your browser using the HTML5 Canvas API. Nothing is uploaded to any server. You can verify this by disconnecting from the internet after loading the page — the tool works offline.

Tip: Apple automatically applies rounded corners (squircle mask) to your app icon — do NOT pre-round the corners yourself. Submit a perfectly square icon and let the OS handle the shape. Pre-rounded icons look wrong because Apple's corner radius changes between iOS versions.

Tips for iOS App Icons

No transparency allowed — Apple rejects icons with alpha channels. Use a solid color background. If your logo is transparent, add a background before generating.
1024×1024 is your master — design and export at 1024×1024, then generate all smaller sizes from this single source. Never design at a small size and scale up.
Keep it simple — iOS app icons are often viewed at 60px on the home screen. Complex detailed artwork becomes unrecognizable. Bold shapes, limited colors, and a single focal point work best.
Don't add shadows or depth effects — iOS adds subtle shadows automatically. Adding your own can make the icon look double-shadowed.
Test at actual sizes — use your phone to view the icon at real size. What looks good at 1024px may be illegible at 60px.
