免费 Favicon 生成器
用 logo、图标或图片在本地生成 favicon.ico 和常用 PNG 尺寸。
先在本地生成 favicon ICO 和 PNG,再放进网站。
关于这个工具:免费 Favicon 生成器
Generate favicon.ico and common PNG favicon sizes locally in the browser from a logo or source image. 无需上传——全部处理都在你的浏览器本地完成,兼顾隐私与速度。
常见用法
- favicon 很小,建议使用方形、高对比度图标。
- favicon.ico 适合兼容旧浏览器,512 PNG 适合 PWA 或应用图标。
一套 favicon 到底需要什么
favicon 不是一张图,而是一套:一个老式的 favicon.ico、几个给标签页和书签用的小 PNG,外加一张给主屏幕和安装提示用的大 PNG。用同一张方形源图生成,标志才不会变形。
怎么正经地生成这一套
- 1
从方形、高对比的源图开始
长条 logo 会被补边或压扁。在 512px 好看的细节缩到 16px 会糊,所以判断标准是最小那档。
- 2
在本地生成
缩放发生在你的浏览器里,未公开的品牌标志不会被上传,也不消耗积分。
- 3
.ico 和 PNG 都要给
浏览器、订阅器和老爬虫仍按约定请求 /favicon.ico。生成器给的 HTML 片段已覆盖标准写法。
favicon 常见问题
- 到底需要哪几档尺寸?
- favicon.ico 应付老式请求,32x32 给高分屏标签页,180x180 给 iOS 主屏幕,512x512 给 web app manifest。
- 为什么新 favicon 不生效?
- 浏览器缓存图标非常狠。直接打开图标地址确认服务端已经是新文件,再强刷页面。
- 生成 favicon 要消耗积分吗?
- 不用。它在本地运行且免费;积分只用于生成新的 3D 模型。
