Favicon Generator

Generate a full favicon set — every standard PNG size, a real favicon.ico, a manifest, and ready-to-paste HTML — from one image. Runs entirely in your browser; nothing you upload is ever sent anywhere.

Quick Learn

A "favicon" isn't really one file anymore — modern sites ship a small family of icons at different sizes for different contexts: a tiny one for the browser tab, a larger one for an iOS home-screen shortcut, and even larger ones for Android and PWA install prompts. The classic favicon.ico is itself a small container format that can bundle several sizes (commonly 16×16, 32×32, and 48×48) into a single file, which is why some browsers still fall back to requesting /favicon.ico directly even when a page doesn't link one explicitly.

This tool takes one image, fits it into a square (centering it with transparent padding if it isn't already square), and renders every standard size from that single source — including packing the .ico file's directory format by hand, entirely in your browser. It also generates the manifest and the exact <link> tags to drop into your page's <head>.

Best Practices

  • Start from a square (or close to square) source image — a non-square image gets centered with transparent padding, which can look off if the original artwork wasn't designed with that space in mind.
  • Use simple, high-contrast artwork for the smallest sizes (16×16, 32×32) — fine detail that looks fine at 512px often becomes an illegible smudge at browser-tab size.
  • Keep the generated file names as-is (favicon.ico, apple-touch-icon.png, etc.) — they're the conventional names most frameworks, CMSs, and the HTML snippet here expect by default.
  • Add the site.webmanifest reference only if your site actually serves that file at the root — an unreferenced or missing manifest just produces a harmless 404, but it's easy to forget once and confuse yourself later.

Frequently Asked Questions

No. Every size is rendered, and the .ico file is packed, entirely in your browser using canvas — nothing you upload is sent to a server or stored anywhere.
