NPM version Build Status

A Node.js module for generating favicons and their associated files. Originally built for Google's Web Starter Kit and Catalyst. Installed through NPM with:

npm install favicons


To use Favicons, require the appropriate module and call it, optionally specifying configuration and callback objects. A sample is shown on the right. The full list of options can be found on GitHub.

Favicons generates its icons locally using pure Javascript with no external dependencies.

Please note: Favicons is tested on Node 14 and above.

import { favicons } from "favicons";

const source = "test/logo.png"; // Source image(s). `string`, `buffer` or array of `string`

const configuration = {
  path: "/", // Path for overriding default icons path. `string`
  appName: null, // Your application's name. `string`
  appShortName: null, // Your application's short_name. `string`. Optional. If not set, appName will be used
  appDescription: null, // Your application's description. `string`
  developerName: null, // Your (or your developer's) name. `string`
  developerURL: null, // Your (or your developer's) URL. `string`
  cacheBustingQueryParam: null, // Query parameter added to all URLs that acts as a cache busting system. `string | null`
  dir: "auto", // Primary text direction for name, short_name, and description
  lang: "en-US", // Primary language for name and short_name
  background: "#fff", // Background colour for flattened icons. `string`
  theme_color: "#fff", // Theme color user for example in Android's task switcher. `string`
  appleStatusBarStyle: "black-translucent", // Style for Apple status bar: "black-translucent", "default", "black". `string`
  display: "standalone", // Preferred display mode: "fullscreen", "standalone", "minimal-ui" or "browser". `string`
  orientation: "any", // Default orientation: "any", "natural", "portrait" or "landscape". `string`
  scope: "/", // set of URLs that the browser considers within your app
  start_url: "/?homescreen=1", // Start URL when launching the application from a device. `string`
  preferRelatedApplications: false, // Should the browser prompt the user to install the native companion app. `boolean`
  relatedApplications: undefined, // Information about the native companion apps. This will only be used if `preferRelatedApplications` is `true`. `Array<{ id: string, url: string, platform: string }>`
  version: "1.0", // Your application's version string. `string`
  pixel_art: false, // Keeps pixels "sharp" when scaling up, for pixel art.  Only supported in offline mode.
  loadManifestWithCredentials: false, // Browsers don't send cookies when fetching a manifest, enable this to fix that. `boolean`
  manifestMaskable: false, // Maskable source image(s) for manifest.json. "true" to use default source. More information at https://web.dev/maskable-icon/. `boolean`, `string`, `buffer` or array of `string`
  icons: {
    // Platform Options:
    // - offset - offset in percentage
    // - background:
    //   * false - use default
    //   * true - force use default, e.g. set background for Android icons
    //   * color - set background for the specified icons
    android: true, // Create Android homescreen icon. `boolean` or `{ offset, background }` or an array of sources
    appleIcon: true, // Create Apple touch icons. `boolean` or `{ offset, background }` or an array of sources
    appleStartup: true, // Create Apple startup images. `boolean` or `{ offset, background }` or an array of sources
    favicons: true, // Create regular favicons. `boolean` or `{ offset, background }` or an array of sources
    windows: true, // Create Windows 8 tile icons. `boolean` or `{ offset, background }` or an array of sources
    yandex: true, // Create Yandex browser icon. `boolean` or `{ offset, background }` or an array of sources
  shortcuts: [
    // Your applications's Shortcuts (see: https://developer.mozilla.org/docs/Web/Manifest/shortcuts)
    // Array of shortcut objects:
      name: "View your Inbox", // The name of the shortcut. `string`
      short_name: "inbox", // optionally, falls back to name. `string`
      description: "View your inbox messages", // optionally, not used in any implemention yet. `string`
      url: "/inbox", // The URL this shortcut should lead to. `string`
      icon: "test/inbox_shortcut.png", // source image(s) for that shortcut. `string`, `buffer` or array of `string`
    // more shortcuts objects

try {
  const response = await favicons(source, configuration);

  console.log(response.images); // Array of { name: string, contents: <buffer> }
  console.log(response.files); // Array of { name: string, contents: <string> }
  console.log(response.html); // Array of strings (html elements)
} catch (error) {
  console.log(error.message); // Error description e.g. "An unknown error has occurred"

The default sources are as follow (groupped by platform):

  "android": [
  "appleIcon": [
  "appleStartup": [
  "favicons": [
  "windows": [
  "yandex": [

You can programmatically access Favicons configuration (icon filenames, HTML, manifest files, etc) with:

import { config } from "favicons";

Below you will find a simple working example to generate an output. Amend the src, dest, htmlBasename and configuration constants to suit your own needs.

import favicons from "favicons";
import fs from "fs/promises";
import path from "path";

const src = "./icon.svg"; // Icon source file path.
const dest = "./favicons"; // Output directory path.
const htmlBasename = "index.html"; // HTML file basename.

// Configuration (see above in the README file).
const configuration = {
  path: "/favicons",
  appName: "My Great App",
  appShortName: "Great App",
  appDescription: "A great application to test itgalaxy/favicons.",
  // Extra options...

// Below is the processing.
const response = await favicons(src, configuration);
await fs.mkdir(dest, { recursive: true });
await Promise.all(
    async (image) =>
      await fs.writeFile(path.join(dest, image.name), image.contents),
await Promise.all(
    async (file) =>
      await fs.writeFile(path.join(dest, file.name), file.contents),
await fs.writeFile(path.join(dest, htmlBasename), response.html.join("\n"));


Why are you missing certain favicons?

Because pure Javascript modules aren't available at the moment. For example, the El Capitan SVG favicon and the Windows tile silhouette ability both require SVG support. If modules for these task begin to appear, please jump on the appropriate issue and we'll get on it ASAP.

Thank you
