最佳实践

  • Start from high-resolution square artwork when possible.
  • Keep the subject centered and avoid tiny text inside small icons.
  • Use transparent backgrounds only when the mark remains visible on light and dark surfaces.
  • Use consistent file paths between exported files and HTML code.
  • After replacing favicons, clear browser cache or change filenames if the old icon remains visible.

常见错误

  • Uploading a low-resolution source and expecting sharp large icons.
  • Using artwork that touches the edge and gets clipped after rounding or cover mode.
  • Shipping only favicon.ico and forgetting Apple Touch Icon or manifest icons.
  • Leaving HTML paths that do not match the files in the public folder.
  • Not previewing 16x16 and 32x32 outputs before release.

常见问题

What image size should I upload?

A square 1024x1024 image is a strong source because it can scale down cleanly to smaller app icon sizes.

Can I generate both iOS and Android icons?

Yes. Choose all platforms or filter the output to iOS, Android, or PWA.

Does this tool upload my app icon?

不会。处理过程在浏览器本地完成,文件不会上传到 LumaTool 服务器。

What is the difference between app icon and favicon?

App icons are used by mobile launchers, stores, and installed apps. Favicons are primarily used by websites, browser tabs, bookmarks, and PWA metadata.

Why do I need 192x192 and 512x512 icons?

These are common PWA manifest sizes used for install prompts, launchers, and high-resolution surfaces.

Can I use the generated icons in a PWA?

Yes. Use the Android/PWA PNG files and copy the generated manifest icons JSON into your web manifest.
