Frequently Asked Questions (FAQ)

Why is my icon blurry at certain sizes?

Blurry icons are usually due to insufficient source image resolution. We recommend:

  • • Use a source image of at least 1024×1024 pixels
  • • Prefer vector (SVG) or high‑resolution PNG
  • • Ensure key elements in your icon are large and clear
  • • Avoid excessive detail in the source image—details get lost at small sizes

How can I ensure consistent display across different platforms?

Platform differences are normal, but you can optimize with these tips:

  • • Keep important content inside the central safe zone (avoid edges)
  • • Use high‑contrast designs for clear recognition at small sizes
  • • Check real‑time preview for both platforms in the right panel
  • • iOS adds rounded corners automatically; Android shapes vary by theme—design accordingly

Does it support transparent backgrounds?

Yes, transparent backgrounds are fully supported:

  • • Transparent areas in uploaded PNGs are preserved
  • • Generated icons maintain original transparency
  • • For platforms requiring opaque backgrounds (e.g., iOS App Store), white background is added automatically
  • • Consider how transparency will look on different backgrounds

What file formats can I generate?

Currently, icons are generated primarily in PNG format:

  • • All icons are generated as PNG (recommended cross‑platform format)
  • • PNG supports transparent backgrounds and high‑quality compression
  • • For Android, WebP may offer better compression but requires separate conversion
  • • iOS App Store icons require PNG with no transparency

Is this tool free? Are there any limitations?

Yes, App Icon Studio is completely free:

  • • Free to use, no registration or login required
  • • No usage limits
  • • No image size limits (though large images may take longer to process)
  • • All processing happens in‑browser, no server costs
  • • Future advanced features may be added, but core functionality will remain free

How do I integrate generated icons into my project?

Integration steps vary by platform:

  • iOS (Xcode): Drag icons into the AppIcon set in Assets.xcassets
  • Android (Android Studio): Copy icons to res/mipmap‑*dpi/ folders
  • React Native: Use react‑native‑make tool or manually place in ios/ and android/ directories
  • Flutter: Update icon configuration in pubspec.yaml and place in appropriate directories

The generated ZIP is already organized by platform and size for easy use.
