Free app icon resizer

Resize one app icon into every iOS and Android size

Already have a finished app icon? Upload one square image and export App Store, Google Play, Xcode, and Android launcher assets. It runs in your browser, with no signup, no upload, and no watermark.

How it works

  1. 1. Upload a square source

    Start with a 1024 x 1024px PNG or another square image. Non-square files are blocked so important icon details are not cropped silently.

  2. 2. Preview the icon treatments

    Check how the same source reads as an iOS app icon, Android launcher icon, and App Store marketing icon.

  3. 3. Download the icon zip

    Export iOS AppIcon.appiconset files, Android launcher icon sizes, and a Google Play icon in one browser-generated zip.

iOS and Android app icon sizes

A 1024 x 1024px square source covers the App Store, Google Play, iPhone, iPad, and Android launcher sizes. The resizer exports the common production assets below. For current platform requirements, check Apple's Xcode app icon guide and Android's density guidance.

From app icon to app screens

The icon is one launch asset. The screens still decide whether the app feels trustworthy. Use Sleek to design the mobile app screens, then pair those screens with your icon and listing assets before launch.

Questions, answered. Everything to know before you start.

What size should my source app icon be?
Use a square 1024 x 1024px PNG for the cleanest result. The tool can export from smaller square images, but the App Store and Google Play icons look sharper from a 1024px source.
Are my app icon files uploaded?
No. The app icon resizer runs in your browser with the Canvas API. Your source image stays on your device, and the zip is created locally.
Which iOS app icon sizes does this export?
The zip includes the common iPhone, iPad, iPad Pro, and 1024px App Store marketing icon sizes, plus an AppIcon.appiconset Contents.json file for Xcode.
Which Android app icon sizes does this export?
The zip includes mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi launcher icons and a 512px Google Play icon.
Does this create Android adaptive icons?
No. This export creates raster launcher PNGs and a Google Play icon. Android adaptive icons still need foreground and background layers configured in your app project.
Can this generate a new app icon from a prompt?
Yes. Use the free AI app icon generator to create an icon from a text prompt, then it exports every size automatically. This resizer is for when you already have a finished square icon.
