About Favicon Tools

Last updated: 2026-05-07

Favicon Tools is a free, browser-based favicon generator that turns a single source image into the full inventory of icons that modern browsers, operating systems, and progressive web apps expect. We built it because exporting twenty PNGs by hand, hand-rolling an ICO, and stitching together a manifest.json is the kind of tedious chore that quietly burns hours of engineering time on every new project.

What Favicon Tools is

At its core, Favicon Tools is a generator: drop in a square logo and we produce a clean kit containing a multi-resolution favicon.ico, the canonical Apple Touch Icons, the full set of Android home-screen sizes, an OpenGraph-ready preview image, and a manifest.json wired to the right paths. The same tool also offers a verifier that audits any live URL, so teams can confirm their existing favicon coverage before a rebrand, launch, or compliance review.

You can start a generation from the home page with an image upload, or open the guided create flow to design an icon from scratch using initials, an emoji, or a simple geometric shape. Both paths end in the same downloadable zip and the same paste-ready HTML snippet for your <head>.

The problem we solve

Favicons look trivial until you ship something. Then the bug reports arrive: the iOS share sheet pulls the wrong image, the Android install prompt shows a blurry square, the Chrome tab still displays the framework default, and the staging environment is indistinguishable from production. None of these problems are interesting to solve by hand. They are mechanical, repetitive, and easy to forget when you are focused on shipping the actual product.

A complete favicon kit involves more than two dozen output files at specific sizes, an ICO container that bundles legacy resolutions, mask icons for Safari pinned tabs, manifest metadata for installability, and a chunk of HTML that has to reference all of it correctly. Getting one detail wrong usually means a silent regression rather than a build failure, which is the worst kind of bug. Favicon Tools removes that surface area entirely.

How it works

Image processing happens in your browser using sharp on the server only when needed for the final ICO assembly. Your source image is resized to every required dimension, sharpened where appropriate, and packaged with a manifest that points to predictable /icons/ paths. We do not store your uploads after the download completes.

What you get in the kit

Who built this

Favicon Tools is built and maintained by Mike Carter (@the_mewc), an indie developer who got tired of writing the same icon generation script for every new side project. The site began as a weekend utility and grew into a small toolbox after enough friends asked to use it on their own launches.

We write about what we learn on the Favicon Tools blog, including practical guides on manifest design, environment-specific icons, and how to audit favicon coverage at scale. Bylines on every article point back to a real person, because we think readers deserve to know who is giving them advice about their site.

Our principles

We try to keep three rules in mind when we make changes to the product:

  1. Free should mean free. The core generator does not require an account, a credit card, or an email address. If we ever add paid features, the basic kit stays free.
  2. Output should be standards-compliant. We follow the current platform guidance from Apple, Google, and the W3C web app manifest spec rather than shipping vanity sizes nobody uses.
  3. Privacy should be the default. Uploaded images are transient. We do not train models on your art, and we do not sell your usage data.

Get started

If you have a logo handy, head to the home page and drop it in. If you want to design something from initials or an emoji, try the create flow. If you already have a site live and want to know what it looks like to crawlers, run it through the verifier. And if you have feedback or want to talk shop, the contact page has a real email address that reaches a real person.
