Create Favicon PNGs from Your Logo

适用场景

Favicons are small but visible everywhere: tabs, bookmarks, and mobile home screens. Start from a crisp logo or mark, export a few square PNGs, and wire them in your HTML metadata.

从任意图片生成方形 PNG 网站图标。

打开 网站图标生成 →

步骤

  1. 1Prepare a square or nearly-square source image (SVG or high-res PNG is ideal).
  2. 2Upload the file and preview how it scales.
  3. 3Download 16×16, 32×32, and 48×48 PNGs as needed.
  4. 4Reference the icons in your site head (and PWA manifest if applicable).
  5. 5Clear CDN/browser cache if an old icon persists after deploy.

示例

  • Product logo simplified to a single mark for 16×16 clarity.
  • App icon exported at 32×32 for desktop tab crispness.

应避免

  • Using a wide banner that becomes unreadable at 16×16.
  • Forgetting to test on both light and dark browser chrome.
  • Shipping only one size when platforms expect multiple.
