Faviconry

Faviconry is a free browser-based favicon generator. It turns one SVG into every favicon format a modern website needs, from a multi-resolution ICO to PNGs for iOS, Android, and PWAs, packaged as a single ZIP.

What problem does it solve?

Shipping a favicon used to mean exporting one file. A modern site now needs roughly nine. Browsers want an ICO. iOS wants a 180-pixel Apple touch icon. Android wants 192 and 512. Progressive web apps want a manifest. Most generators online either mangle SVG paths, paywall the export, or upload the source file to a remote server. Faviconry was built to do the boring work locally and ship the full set in one click.

How it works

Drop an SVG into the page. Faviconry rasterises it in the browser using the Canvas API at every required resolution, generates a multi-resolution ICO, writes a site.webmanifest with sensible defaults, and bundles everything into a single ZIP. No upload, no account, no rate limit. The whole pipeline runs client-side, so even a sensitive or unreleased logo never leaves the device.

Whom it’s for

Designers and developers who already have a working SVG mark and want the full favicon set in under a minute. It assumes the source is clean and pre-cropped. It does not try to design the icon for you.

Tech

Vanilla JavaScript, the Canvas API for rasterisation, JSZip for packaging, and a small custom encoder for the multi-resolution ICO format. No build step, no framework, no dependencies beyond the zip library.

Frequently asked questions

What is Faviconry?

Faviconry is a free browser-based favicon generator. Drop in one SVG and it returns every favicon format a modern site needs, including ICO, PNG sizes for iOS and Android, and a web app manifest.

Which favicon files does Faviconry produce?

A multi-resolution favicon.ico, PNGs at 16, 32, 48, 180, 192, and 512 pixels, an Apple touch icon, and a site.webmanifest for PWA installs.

Does my SVG leave my device?

No. Everything runs in the browser. There is no upload, no analytics on the file itself, and no server round-trip.

Is Faviconry free?

Yes. It runs entirely in the browser, requires no signup, and never uploads your SVG to a server.
