Upload an image and generate app icons in all required sizes for iOS, Android, and web with rounded corners.
App Icon Generator takes uploaded artwork and produces app icon variants for iOS, Android, and web use. It resizes the source for multiple platform targets and applies a rounded-corner treatment, avoiding repeated manual exports from an image editor. Processing stays in the browser, which is relevant when the artwork belongs to an unreleased product. The common surprise is that a rounded square image is not necessarily a platform-native masked or adaptive icon. Some platforms apply their own masks or require additional resource structure.
Upload the master icon image, then generate the platform variants you need. The tool derives multiple output dimensions from that single source and applies its corner treatment consistently. Starting with a square, sufficiently large image reduces the risk of unintended cropping, soft upscaled edges, or mismatched composition among the resulting iOS, Android, and web icons.
The generated variants address the different raster sizes used by the selected platform groups. They remain image assets, so their role in a project still depends on platform configuration. An iOS project may reference icons through an asset catalog, Android may require launcher resources, and a web app must identify its icons in HTML or a web app manifest.
No, not merely because it has rounded corners or several raster sizes. An Android adaptive icon has separate foreground and background layers that the system can mask and animate. Use a generated flat image where an ordinary raster icon is accepted, but verify separately whether your Android project requires adaptive icon resources.
Use a square master with enough resolution for the largest output you intend to generate. Keep essential artwork away from the edges so rounding or platform masks do not remove it. Avoid tiny text and fine detail that will not survive reduction. Whether transparency is appropriate depends on the destination platform and icon role.
