Favicon Generator

How Favicon Generation Works

A favicon needs to render at many sizes — 16x16 in browser tabs, 32x32 on retina displays, 180x180 for iOS home screens, 192x192 and 512x512 for Android. Toolkiya takes your source image (PNG, JPG, or SVG), draws it onto a canvas at each target size, and exports each canvas as a PNG. The classic favicon.ico is built by packing the smaller PNG variants into the ICO container format.

All of this runs in your browser using the Canvas API and a small ICO encoder written in JavaScript. The output is a ZIP bundle containing favicon.ico, the various PNG sizes, an Apple touch icon, and a web app manifest with the correct icon references — ready to drop into your site's /public folder.

When to Generate Favicons

Launching a new site and needing a complete favicon set for browsers, iOS, and Android. Replacing the default Vite or Next.js favicon before going public. Updating a brand refresh across an existing site's icon set. Generating icons from a logo for a small internal tool. Producing a touch icon for a progressive web app so it looks polished when installed.

Why Generate Favicons in Toolkiya

Brand assets and unreleased logos are sensitive — you do not want them sitting on a third-party generator's server before launch. Toolkiya processes the source image entirely in your browser using canvas, so the file never leaves your tab.

There is no signup, no per-image cap, no watermark on the output, and no daily quota. The ZIP bundle is generated locally and downloads with no tracking attached, so you can use it on any commercial site without licensing concerns.

Tips for Crisp Favicons

Start with a square source at 512x512 or larger so downscaling stays sharp. Avoid fine detail that disappears at 16x16 — favicons are read at thumbnail size, not poster size. SVG sources give the cleanest results because each target size is rasterized fresh. Test the result against both light and dark browser themes; a logo that vanishes on a dark tab is a common miss.
