生成网站图标网站图标提示
- 1Use an .ico file containing 16×16, 32×32, and 48×48 versions for maximum browser compatibility
- 2Always provide a 180×180 Apple Touch Icon — iOS uses it for home screen bookmarks
- 3Include both 192×192 and 512×512 PNG icons in your web app manifest for PWA support
- 4Use an SVG favicon for the best Retina quality on modern browsers with a PNG fallback for older ones
- 5Maskable icons should keep key content within the inner 80% of the image (safe zone)
- 6Avoid fine details at 16×16 — they disappear at that size; opt for a bold, simple mark
- 7Use a transparent background for PNG favicons so they adapt to light and dark browser chrome
