How to Create App Icons for Android, iOS & Web — Step by Step
Generating professional app icons no longer requires Photoshop or paid tools. This free app icon generator lets you upload any logo, remove its background automatically, and export a complete ZIP package with all required sizes for Android, iOS, PWA, and Flutter — in under 60 seconds.
Step 1 — Upload Your Logo or Image
Click the upload area or drag and drop your PNG, JPG, or WEBP file. For best quality, use a square image of at least 512×512 pixels. Higher resolution source files (1024×1024) produce sharper icons on Retina and XXXHDPI displays.
Step 2 — Remove Background Automatically
Enable Magic Image BG Removal to strip the background color from your logo using pixel-level color detection. Adjust the Smart Tolerance slider to fine-tune how aggressively the tool removes edge pixels. This is ideal for logos with solid white or solid colored backgrounds.
Step 3 — Customize Shape & Style
Choose from Square (standard Android/iOS), Squircle (Google Play adaptive style), or Circle (social-style icons). Use the zoom, padding, rotation, and background color controls to perfectly frame your icon within the canvas.
Step 4 — Select Platforms & Export ZIP
Select your target platforms — Android, iOS, Web Favicon, or Flutter — then click Export Complete ZIP. The downloaded ZIP contains all icon files organized in the correct folder structure ready to drop into your project.

Frequently Asked Questions
Is this app icon generator completely free?
Yes — 100% free, no account required, no watermarks, unlimited downloads.
What file formats can I upload?
PNG, JPG, WEBP, and GIF are supported. PNG with transparent background gives the best results for background removal.
Why does iOS not allow transparent icons?
Apple's App Store guidelines require fully opaque icons for the 1024×1024 App Store submission. Transparent pixels are automatically rejected during review. Use a solid background color for iOS exports.
Can I use the Text to Favicon feature for my website?
Yes. Switch to the Text to Favicon tab, type 1–3 characters (like your brand initial), choose font, color, and background, then export. Perfect for quick branded favicons without any design software.
How do I add the favicon to my Blogger blog?
Upload your generated favicon PNG to an image host, copy the URL, then go to Blogger → Theme → Edit HTML and add: <link rel='icon' href='YOUR_URL' type='image/png'/> inside the <head> section.
Does the background removal work on complex images?
The Magic BG Removal works best on logos with solid, uniform background colors (white, black, single color). For complex photos with gradients, use a PNG with pre-existing transparency for best results.
What is the best image format for a favicon?
PNG is the best format for modern favicons — it supports transparency and is universally supported. ICO format is recommended for legacy browser compatibility as it bundles multiple sizes (16x16, 32x32, 48x48) in one file. For maximum compatibility, use both formats together.
What are the standard app icon sizes for Android and iOS?
Android requires: mdpi (48px), hdpi (72px), xhdpi (96px), xxhdpi (144px), xxxhdpi (192px), Play Store (512px). iOS requires: 20px, 29px, 40px, 58px, 60px, 80px, 87px, 120px, 180px, and 1024px for App Store submission. This tool generates all sizes automatically.
What is the difference between ICO and PNG favicons?
ICO files bundle multiple resolutions in one file and work in all browsers including legacy IE. PNG favicons are simpler, smaller, and fully supported by all modern browsers. Best practice: serve favicon.ico for legacy support and <link rel="icon" type="image/png"> PNG files for modern browsers.
Why is my website favicon pixelated or blurry?
A blurry favicon is caused by upscaling a low-resolution source image. Always upload a source image of at least 512×512 pixels. This tool downscales from your high-resolution source to generate all smaller sizes, ensuring sharp, crisp results at every dimension.
