Free App Icon Generator — Android, iOS & Flutter Icons in One Click

AppIconForge is a free, browser-based app icon generator that turns any portrait, landscape, or square image into a complete set of Android mipmap icons, iOS AppIcon.appiconset, and Flutter-ready asset bundles — all packaged as a ZIP file. The tool automatically fits rectangular artwork into a square canvas, resizes every required dimension, and converts browser-supported image formats to PNG. No upload required, no signup, no watermarks. Everything runs 100% locally in your browser using WebAssembly and HTML5 Canvas.

What you get

Android legacy icons — mdpi through xxxhdpi (48–192px) for all Android versions
Android adaptive icons — foreground + background layers with safe-zone masking for modern launchers (Android 8.0+)
iOS icons — all 17 required sizes from 20×20 to 1024×1024 (App Store marketing icon included)
Flutter ready — organized folders matching the flutter create convention for instant integration
ZIP download — one file, properly structured for Android Studio, Xcode, and VS Code

Frequently asked questions

What file formats are supported?

Any image format your browser can decode, including PNG, JPEG, WebP, GIF, SVG, BMP, and more. Rectangular images are automatically fitted into a square without distortion, and small images are resized for every platform requirement.

Does it work offline?

Yes. Once the page loads, the entire generation runs locally using WebAssembly. You can disconnect from the internet and still download your ZIP.

Are the icons Play Store / App Store ready?

Yes. Every required size for Google Play (512×512 high-res, adaptive foreground/background) and Apple App Store (1024×1024 marketing, all @1x/@2x/@3x sizes) is included.

Can I use this for Flutter apps?

Absolutely. The ZIP includes the assets/images/ folder structure Flutter expects — just unzip into your project and add to pubspec.yaml.

What about adaptive icon safe zones?

We automatically calculate the safe zone (66% of icon diameter) and mask the background layer so your foreground content never gets clipped by OEM masks.
