A simple, multi-size ICO converter

An .ico file bundles multiple resolutions so a single favicon works everywhere. This converter takes a PNG, JPG, WebP, or SVG and writes a favicon.ico containing 16, 32, and 48 px, right in your browser — no desktop software needed.

Because the format also matters for sharing the whole favicon set, the zip includes PNG icons up to 512 px, an apple-touch-icon, Android icons, and a site.webmanifest alongside the .ico.

How to make a favicon.ico

  1. Add an image — drag & drop, paste, or pick a PNG, JPG, WebP, or SVG.
  2. Choose the background — transparent for tabs, or a solid color for a filled icon.
  3. Add padding if needed — a small margin keeps art clear of rounded corners.
  4. Download — the favicon.ico and the rest of the set come in one zip.

Tip: one .ico, every browser

Place favicon.ico at the root of your domain and reference it with a single link tag. Older browsers find it automatically; modern ones use the PNG and manifest icons you also get here.

favicon.ico: sizes and where each is used

.ico 格式将多种分辨率打包在一起,使单个网站图标在从 Internet Explorer 到最新 Chrome 的各处都能工作。你转换的任何图像都会写入一个包含以下尺寸的 favicon.ico:

Size File Where it's used
16 × 16 px inside favicon.ico 1× 密度下日常的标签页和地址栏图标。
32 × 32 px inside favicon.ico Retina 的标签页和书签图标,以及 Windows 快捷方式。
48 × 48 px inside favicon.ico 桌面和 Windows 场景可选择的更大条目。

Format & container

真正的 ICONDIR 头部指向每个 PNG 编码的尺寸,因此浏览器读取一个文件,并为当前场景选择最清晰的分辨率——无需为旧版支持单独准备大小文件。

How it's wired into your page

                <link rel="icon" href="/favicon.ico" sizes="any">
<!-- 把 favicon.ico 放在域名根目录;旧浏览器会自行找到 -->
              

Tip

把 favicon.ico 放在你域名的根目录(例如 example.com/favicon.ico):即使没有 link 标签,浏览器也会默认请求该路径,这正是旧版回退仍然有效的原因。

What is an .ico file?

It's an icon container that can store several image sizes in one file. Favicons use it so browsers can choose the right resolution for tabs, bookmarks, and the address bar.

Which sizes go into the .ico?

This converter writes 16, 32, and 48 px into the favicon.ico — the standard set browsers select from.

Where is the file created?

On your own device, in the browser. How any data associated with the tool is handled is described in our privacy policy.

Can I also get PNG and Apple icons?

Yes — the download includes PNG favicons, an apple-touch-icon, Android icons, and a web manifest in addition to the .ico.
