App Icon Generator

Among ToolsMonk's image tools, AppIcon covers a single everyday need: design, generate with ai, or resize an app icon into every size ios, android, macos and the web need. Open the page and start working, with no download or sign-up standing between you and the result.

This tool is especially useful for workflows such as setting up app icons for a new ios or android project without hunting through size tables, refreshing every icon across an existing app after a rebrand, and producing favicons, maskable pwa icons and a manifest for a website launch. Because it runs directly in your browser, you can use it on desktop, tablet, or mobile while keeping the process fast and easy for one-off tasks as well as repeat work.

If you have been searching for app icon generator, app icon maker, and app icon resizer, this page covers those jobs with a clean interface, instant output, and no paywall in the way.

AppIcon turns a single square image into the complete icon set a project needs, across iOS, iPadOS, macOS, watchOS, Android, the Play Store, Windows, the web and browser extensions. The difference between this and a folder of resized PNGs is everything that comes with them: Contents.json for each Apple asset catalog, the mipmap-anydpi-v26 XML that binds Android's adaptive layers together, a web app manifest, an HTML head snippet and a README that explains where every file belongs.

The part worth understanding is masking. Android draws an adaptive icon on a 108dp canvas and lets each manufacturer crop it to a circle, a squircle or a rounded square, so only the central 66dp is documented as safe. Most generators pad your logo to that figure and stop there, which quietly loses the corners of a square logo on circular launchers. This tool draws the safe zone over your artwork, previews all three mask shapes, and measures the proportion of your logo that each one would remove, so a crop is something you decide about rather than discover on a phone.

A few files have rules of their own and the tool applies them without being asked. The App Store 1024 icon is written with no alpha channel at all, because Apple rejects an icon that carries one even when nothing in it is transparent. The apple-touch-icon is flattened, because iOS composites it on black and a transparent one becomes a dark square on the home screen. Maskable PWA icons are padded to the web standard's safe circle and kept separate from the ordinary icons, since the same file cannot serve both roles well. The Windows icon is a genuine multi-resolution .ico rather than one image renamed.

Beyond sizing, you can set padding, nudge and rotation, choose a solid, gradient or automatically sampled background, trim empty transparent margins, derive an Android 13 themed monochrome layer, and stamp a corner ribbon on development builds so testers never install the wrong one by mistake. Everything renders in your browser with the Canvas API and downloads as a single ZIP, which matters more than usual for app icons: they are normally unreleased branding, and here they never leave your machine.
