Adding icons to a Next.js App Router project

The Next.js App Router has file-based metadata for icons. Put favicon.ico, icon.svg (or icon.png) and apple-icon.png directly in the app/ directory, and Next.js adds the correct <link> tags to every page for you. You don't need to edit the layout file.

This generator's download uses standard web file names. For the App Router, copy favicon.ico and icon.svg into app/ as they are, and rename apple-touch-icon.png to apple-icon.png. The android-chrome PNGs and site.webmanifest go in public/, and you link the manifest from your root layout metadata.

If you still use the Pages Router, put every file in public/ and paste the HTML snippet from the studio into _document.tsx.

How to use it

  1. 1Generate your icon and download the ZIP.
  2. 2Copy favicon.ico and icon.svg into app/, and rename apple-touch-icon.png to apple-icon.png.
  3. 3Move site.webmanifest and the android-chrome PNGs into public/.
  4. 4Add manifest: "/site.webmanifest" to the metadata export in app/layout.tsx.

Modern Icon Packages vs. ICO/PNG-Only Converters

Web standards have evolved. A single fixed-size PNG or ICO looks soft on high-density screens and can disappear on dark browser tabs.

Frequently Asked Questions

Where do I put the downloaded files in a Next.js project?

Place favicon.ico, icon.svg, and apple-icon.png directly in your /app root directory. Next.js handles serving and caching automatically.

Why is my old favicon still showing in Next.js?

Delete any old favicon.ico in public/ (it can shadow the app/ version), restart the dev server and hard-reload. Browsers cache favicons for a long time.

Can I generate the icon dynamically with icon.tsx?

Yes. Next.js supports app/icon.tsx with ImageResponse, but a static icon.svg is smaller, supports dark mode and needs no server rendering.
