App Icon Size Checker and Resizer for the App Store and Google Play

The short answer for the two stores is two numbers. The App Store icon size is 1024 x 1024 pixels: Apple's Human Interface Guidelines list a square 1024 x 1024 px layout for iOS, iPadOS and macOS, and Apple's Xcode documentation says a new iOS project makes every smaller size from that one image. The Google Play icon size is 512 x 512 pixels, as a 32 bit PNG of at most 1024 KB, according to Google's Play Console Help. Both figures were read on the companies' own pages on October 13, 2026.

Those are the app icon dimensions for the store listings. Inside the app, the two systems differ. On Apple platforms the same 1024 image, or a layered file made in Icon Composer, becomes the icon on the Home Screen, in Settings and in notifications, and the system scales it. On Android the icon on the phone is a separate asset called an adaptive icon, measured in density independent pixels and built from layers. Google states plainly that the store icon does not replace the launcher icon.

So an app that ships on both stores needs three things: a 1024 x 1024 square for Xcode, a 512 x 512 PNG for the Play Console, and an adaptive icon in the Android project. The tool above checks and makes the first two. The tables below give every number for all three, with the page each one comes from.

Older guides list a dozen iOS icon files: 180 pixels for the iPhone Home Screen, 167 for iPad Pro, 120 for Spotlight and so on. You no longer export those by hand. Apple's Xcode guide says iOS, iPadOS, tvOS and watchOS apps can generate all icon variations from a single 1024 x 1024 pixel image, that this is the default when you create a new app or a new icon in the asset catalog, and that an existing project with many files should consider switching to the single size.

The choice lives in the asset catalog. Select the icon, open the Attributes inspector and pick Single Size or All Sizes in the menu for each platform. All Sizes is still there for teams who want to draw a simpler icon for the smallest slots, which Apple describes as showing more detail at a larger size. The guidelines add that the system scales your icon to produce the smaller versions that appear in places like Settings and notifications.

The Mac is the exception. The same guide says that for macOS you need to supply an asset for each size when you use an asset catalog. Apple's current pages do not list those sizes, but its archived asset catalog format reference, last updated on April 9, 2018, does, in points: 16, 32, 128, 256 and 512 for the Mac, with 1024 named as the App Store icon. At 2x, 512 points is 1024 pixels, which matches the App Store 2x well the Xcode guide names for the Mac. The tool above makes that one file. It does not make the smaller Mac sizes, or .icns files.

The same archived reference explains the numbers you still see in old tutorials. It lists 60 points as the main iPhone icon, 76 as the main iPad icon, 83.5 as the main iPad Pro icon, 40 for Spotlight results, 29 for Settings and 20 for notifications. Multiply by the screen scale and you get the familiar pixel sizes: 60 points is 120 pixels at 2x and 180 at 3x, and 83.5 points at 2x is 167. The multiplication is ours. With Single Size selected, Xcode does it for you at build time.

There is also a newer route that skips the asset catalog for the icon. Apple's guide to Icon Composer describes a single layered file that stands for the icon on iOS, iPadOS, macOS, watchOS and the App Store, from which the system renders every platform, appearance and size. It is covered in the section on dark and tinted icons below.

Searches for the iOS app icon corner radius come up empty on Apple's side for a reason: Apple does not publish one. The Human Interface Guidelines say that on iOS, iPadOS and macOS icons are square and the system applies masking to produce rounded corners that match the rest of the interface and the bezel of the device. The instruction is to produce unmasked layers, and Apple warns that layers with masking already applied hurt the highlight effects and make edges look jagged. For placement, the guidelines point to the grids in the production templates on Apple Design Resources.

Google gives a number. Google Play's icon design specifications say the store applies the rounded mask and the shadow after upload, with a radius equal to 30 percent of the icon size, and that you should not round the edges of the final asset. So for both stores the right file is a full square with artwork or background running to every edge. This is what the Edges line in the tool above looks for: four see through corners almost always mean the corners were rounded before export.

Transparency is stricter on Apple's side than the guidelines alone suggest. The guidelines say an imported background layer should be full bleed and opaque. The stronger wording shows up at upload. In a thread on Apple's Developer Forums from August 2026, a developer quotes the validation message, numbered 90717, which says the large app icon "can't be transparent or contain an alpha channel" and points to the guidelines. A reply in that thread makes the point that matters: a logo that looks solid can still be a file with an alpha channel embedded.

So a file can fail on something you cannot see. An alpha channel is the part of a PNG that stores how see through each pixel is, and a PNG can hold one even when every pixel is opaque. A PNG from Figma is in that position: its page on export formats says it is not possible to export a PNG without an alpha value. The tool above handles this for the App Store file: it writes the 1024 x 1024 PNG as plain RGB with no alpha channel, and fills any see through parts with white. In an old browser that cannot do this it falls back to an ordinary PNG. The check on the file you drop in still looks only for pixels that really are see through. If an upload returns message 90717, test the 1024 file before you send it again. On a Mac you can test a file in Terminal: the command sips with the option -g hasAlpha, followed by the file name, prints yes or no. We ran it on macOS 26.6 on October 13, 2026.

Two cases need care. Icons made in Icon Composer have triggered the same message for reasons that had nothing to do with the artwork: in a long forum thread that began in August 2025, an Apple engineer treated it as a known issue during the beta period, and several developers reported that turning off Blur on one group of layers let their upload through. And the dark variant of an iOS icon is supposed to be transparent. Apple's Xcode guide asks for the dark icon with a transparent background so the background the system provides can show through. If you drop a dark variant into the tool, the Edges line will warn about it, and for that one file the warning does not apply.

Forum posts are reports from developers. The exact wording and number of a message can change between releases, and neither thread ends with a fix confirmed by Apple.

One icon file is no longer the whole story on Apple platforms. Apple's guidelines say that on iOS, iPadOS and macOS people can choose whether their Home Screen icons are default, dark, clear or tinted. The specifications table lists six appearances: default, dark, clear light, clear dark, tinted light and tinted dark. You can design a variant for each, and the system generates the ones you do not provide. Apple's advice is to keep the icon's main features the same in every appearance and to base the dark icon on the light one.

In an asset catalog, the Xcode guide gives the steps: select the icon, open the Attributes inspector, choose Single Size for iOS, then choose Any, Dark or Tinted in the Appearance menu and drag your files into the image wells that appear. The tinted icon is supplied as a grayscale image and the dark icon with a transparent background. If you supply neither, the system applies its own treatment to your default icon.

The newer route is a layered icon. Apple's guidelines describe iOS, iPadOS, macOS and watchOS icons as a background layer plus one or more foreground layers, which the system renders with Liquid Glass effects such as highlights, refraction and translucency. You draw the foreground layers in your design tool and assemble them in Icon Composer, which is included with Xcode and can also be downloaded from Apple. Its own page lists macOS Tahoe 26.4 or later as the requirement, while Apple Design Resources says macOS Sequoia or later, so check the download page for your Mac. Both say it can export a flattened version of the icon for marketing.

Apple's guide to creating an icon with Icon Composer fills in the working details. Set the canvas to 1024 x 1024 pixels for iPhone, iPad and Mac, or 1088 x 1088 for Apple Watch. Export layers as SVG where you can and PNG where you cannot, and leave out the canvas mask because the system applies it. Organize the layers into at most four groups. Then preview the default, dark and mono appearances, where mono covers the clear and tinted looks. When the file goes into your Xcode project, it replaces the icon in the asset catalog, and Xcode generates images at build time for earlier OS releases.

A layered icon still starts from square artwork at 1024 x 1024, so the size check above applies to the layers you export. What the tool cannot do is build the layered file, preview appearances or make dark and tinted variants. For tvOS and visionOS the layers go into an image stack in the asset catalog instead, with up to five layers on tvOS and up to three on visionOS.

Apple lets an app carry more than one icon. The guidelines say that on iOS, iPadOS and tvOS, and in compatible apps running in visionOS, people can choose an alternate icon in the app's settings, as a sports app might offer one per team. Alternate icons on iOS and iPadOS need their own dark, clear and tinted variants, and all of them are subject to app review. In Xcode, the asset catalog guide says to list the extra icon sets under the Alternate App Icon Sets build setting.

The same build setting is how you test icons on the store. Apple's page on product page optimization describes tests of up to three treatments against your original page, one test at a time, for up to 90 days, shown to people on iOS and iPadOS 15 or later. A treatment can swap the app icon, and a person who downloads from that treatment sees the same icon on their device. Apple recommends waiting until a treatment is ahead or behind the baseline with at least 90 percent confidence.

The catch is in the build. App Store Connect Help on configuring test treatments says any icon you want to test must be part of the app binary for the current App Store version, and that icons must be sized to 1024 x 1024 pixels. The App Icon tab appears only when the binary includes more than one icon. Other test assets, such as screenshots, can be submitted without a new version. If a treatment with an alternate icon wins, Apple reminds you to include that icon when you submit the next version.

So every candidate icon is one more 1024 x 1024 square to check. Run each through the tool above before it goes into the asset catalog, since a test cannot be changed once it has started.

An app icon cannot be a GIF or a video on either store. Google's Play Console Help asks for a 32 bit PNG for the store icon. On Apple platforms the icon is built from still artwork: Apple's Icon Composer guide asks for layers exported as SVG or PNG, and the asset catalog takes still images in its image wells. Neither specification lists an animated format, so a looping logo has to become one still frame before it can be an icon.

The movement people notice comes from the system. Apple's guidelines say icons on iOS, iPadOS, macOS and watchOS take on Liquid Glass effects, such as specular highlights and refraction, that respond to the environment and to people's interactions, and that a focused tvOS icon sways in parallax. On Android, the adaptive icon guide says supported launchers generate visual effects such as parallax or pulsing when people place or move an icon, which is what the outer 18 dp of each layer is reserved for. You design the layers. The motion is not yours to animate.

Changing an icon is possible, in two ways. The main icon ships inside the app, so replacing it means a new version on the App Store and a new build for the Android launcher icon, as the side by side table above shows. Within one version, an iOS or iPadOS app can switch between still icons it already contains: Apple's method for changing the app icon sets the displayed icon to one of the alternate icon sets declared in the build, or back to the primary one. That is how apps offer team or seasonal icons. Each alternate is one more 1024 x 1024 square for the tool above, with its own dark, clear and tinted variants.

The icon is the smallest asset on the listing and the one people see most, in search results, on the Home Screen and beside every review. Once the two files pass, the same care goes into what sits next to them. Screenshots have exact sizes of their own, and the App Store screenshot size checker reads them the way this page reads an icon. The full list is in the reference of App Store screenshot sizes, and the gallery of App Store screenshot examples shows what good sets look like.

The words have limits too. The App Store character counter counts the name, subtitle, keywords and promotional text against Apple's limits, and the App Store description generator drafts them for you. How the icon, the words and the screenshots work together to bring in searches is the subject of the guide to App Store optimization.

An icon also sets the colors for everything you publish about the app. If you are fixing the icon ahead of a release, the app launch checklist covers what else to have ready, and Apple's App Store marketing guidelines explained covers how the icon and the App Store badge may be used in ads and posts. To turn the icon's colors into a palette for the rest of your marketing, try the brand kit generator.
