Resize App Icons for Android and iOS
Prepare your app icons for publication with one click. Our tool resizes icons to all required dimensions for Google Play and the Apple App Store, saving you hours of manual work.
How the Icon Resizer Works
Upload your base icon image - ideally a high-resolution square PNG or SVG. The resizer automatically generates all required sizes for Android and iOS app icons.
Select your target platforms: Android, iOS, or both. The tool uses platform-specific size requirements. Android needs multiple densities (mdpi, hdpi, xhdpi, etc.). iOS requires various point sizes for different devices.
Preview how your icon looks at each size. The resizer applies proper scaling algorithms to maintain quality. Download as a ZIP file with correctly named icons ready for your project's asset folders.
When You'd Actually Use This
Launching a React Native app
Your app is ready but you need icons for both platforms. Upload one master icon. Get all sizes for Android's mipmap folders and iOS's Assets.xcassets.
Submitting to App Store
Apple requires specific icon sizes for App Store Connect. Generate the 1024x1024 App Store icon plus all device-specific sizes from one source.
Publishing on Google Play
Google Play needs a 512x512 high-res icon and adaptive icon layers. Generate all required sizes from your master design in one go.
Updating existing app icons
Rebranding your app? Replace icons across all densities. Upload the new design and regenerate the complete set for both platforms.
Creating PWA icons
Progressive Web Apps need multiple icon sizes too. Use the resizer to generate 192x192, 512x512, and other sizes for your manifest.json.
Preparing app store screenshots
Marketing materials need icons at various sizes. Generate icons for screenshots, promotional graphics, and website previews from one upload.
What to Know Before Using
Start with a large square source.Upload at least 1024x1024 pixels. Larger source files produce better results when scaled down. Never upscale small images - quality degrades.
iOS requires no transparency.Apple adds rounded corners automatically. Don't include rounded corners or transparency in your source. iOS will apply its own masking.
Android supports adaptive icons.Android 8.0+ uses adaptive icons with foreground and background layers. Prepare separate layers for best results on modern Android devices.
Test on actual devices.Icons look different on various screens. Check how your icon appears on real devices before final submission. Home screen backgrounds vary.
Pro tip: Design your icon with a safe zone. Keep important elements within the center 66% of the square. iOS and Android may crop edges differently.
Common Questions
What size should my source icon be?
1024x1024 pixels is ideal. This covers all required output sizes. Minimum 512x512 works but may show quality loss at largest outputs.
What format should I upload?
PNG with transparency works best. SVG is also supported and scales perfectly. Avoid JPG as compression artifacts may appear in smaller sizes.
Do I get all Android densities?
Yes, generates mdpi, hdpi, xhdpi, xxhdpi, and xxxhdpi sizes. Also includes legacy sizes if needed. All standard Android density buckets covered.
What about iOS @2x and @3x?
All iOS scale factors included: @1x, @2x, and @3x for various devices. Names follow Apple's convention for easy integration into Xcode projects.
Can I customize the output sizes?
This tool uses standard platform requirements. For custom sizes, use a general image resizer. This focuses on Android and iOS specifications.
How are the files organized?
ZIP contains separate folders for Android and iOS. Android uses mipmap folder structure. iOS uses Assets.xcassets naming. Ready to drop into projects.
Does it work for app icons only?
Primarily designed for app icons, but works for any icon set needing multiple sizes. Use for notification icons, settings icons, or custom markers.
