About Favicon Generator / 关于本工具
A favicon is the tiny icon shown in a browser tab, bookmark bar and history list — the little image next to your page title. A site without one looks unfinished and is harder to spot among many open tabs. Browsers and devices ask for the icon in several sizes: 16×16 and 32×32 for tabs, 180×180 for an Apple touch icon when someone saves your site to a phone home screen, and 192×192 / 512×512 for Android and progressive web apps. This tool produces that whole set from a single source image.
favicon 是浏览器标签页、书签栏和历史记录里显示的小图标——标题旁边那张小图。没有它的网站显得没做完，在一堆打开的标签里也更难找。浏览器和设备会要不同尺寸的图标：标签页用 16×16 和 32×32，有人把网站存到手机主屏时用 180×180 的 Apple 触摸图标，安卓和 PWA 则用 192×192 / 512×512。本工具能从一张源图生成这一整套。
Start from the right source / 从合适的源图开始
Use a square image with a simple, bold design — fine detail and small text vanish at 16 px. A solid background usually reads better than transparency at tiny sizes. After downloading, drop the files in your site's root and link them in the page <head>; the .ico file covers older browsers while the PNGs handle modern devices. Generating icons locally means your unreleased logo never gets uploaded anywhere.
用方形、设计简洁醒目的图片——精细的细节和小字在 16px 下会消失。小尺寸下，纯色背景通常比透明更清楚。下载后把文件放进网站根目录，在页面 <head> 里链接它们；.ico 兼顾旧浏览器，PNG 应对现代设备。在本地生成图标，意味着你尚未发布的 logo 不会被传到任何地方。
