App icon generator

Drop a single square artwork and get back a full set of PNG files at every commonly needed size for iOS, from the App Store listing down to a phone's home screen, and for Android, from the Play Store down to the smallest density.

Gives you the common icon sizes for iOS and Android as plain PNG files. It doesn't generate an Xcode asset catalog (Contents.json) or Android adaptive-icon XML — just import the matching size where your build tool asks for it.

How it works

Drop your icon artwork

A large square image, ideally 1024×1024 or bigger.

Check the size previews

Grouped by iOS and Android.

Download the ZIP

Every size, named and sorted by platform.

One piece of artwork, every size your build needs

An app icon has to exist at many different pixel sizes: a small one for a home screen, a larger one for a store listing, and several in between for different screen densities. Producing each one by hand in an image editor is tedious and easy to get slightly wrong. This tool takes one square image and renders every common size for both iOS and Android from it in one pass.

What's included

For iOS: the 1024×1024 App Store icon plus the iPhone and iPad sizes used on the home screen and in settings. For Android: the 512×512 Play Store icon plus the standard mipmap densities from mdpi up to xxxhdpi. Each file is named after its purpose and size, and grouped by platform inside the downloaded ZIP.

What this doesn't do

This produces plain PNG files at the right pixel sizes, not a ready-made Xcode asset catalog with its Contents.json, and not Android's adaptive-icon XML with separate foreground and background layers. Drop the matching PNG in wherever your build tool or asset catalog asks for that size.

Choosing your source artwork

Start as large as you can, ideally 1024×1024 or bigger, since every size is scaled down from it; scaling a small image up to fill a large icon slot produces a soft, blurry result. A simple, centered design also tends to read better once shrunk down to the smallest sizes.

Privacy

Every size is generated locally in your browser. Your artwork is never uploaded anywhere.

Frequently asked questions

What sizes do I get?
The common iOS sizes (App Store, iPhone and iPad) and Android sizes (Play Store and the standard mipmap densities), as separate PNG files grouped by platform.
Does this create an Xcode asset catalog or Android XML?
No, it produces plain PNG files at the right sizes; you still import them into your asset catalog or drawable folders yourself.
What source image should I use?
A large square image, ideally 1024×1024 or bigger, with the design centered, since it's scaled down for every size.
Will a small source image work?
It will produce files, but scaling a small image up to a large icon size looks soft and blurry; start as large as you can.
Can I use a non-square image?
It will be cropped to a square automatically, so a square source gives you the most control over the result.
Is my image uploaded anywhere?
No. Everything happens entirely in your browser.
