Favicon Generator

Create favicon files from an image for your website.

or drop PDF here

Runs in your browser — your file never leaves your device.

Turn one square image into the full set of favicon sizes a site needs, in your browser, without uploading it. Favicon Generator renders PNG icons at 16, 32, 48, 180, 192 and 512 pixels, each cover-fitted to a square, and zips them for download. The 180px file is the Apple touch icon, 192 and 512 serve Android and PWA manifests, and the small ones are what a browser tab actually shows.

How to use Favicon Generator

Click "Select image files" and choose a square image — a logo or an initial on a solid background works best.
Click "Generate Favicons" and wait while each size renders.
Download the ZIP and upload the files your site needs: the 16 and 32 for the browser tab, 180 for iOS, 192 and 512 for a web app manifest.

Who it is for

Favicon Generator is for the last piece of a site that people forget: the little icon in the browser tab, the phone home screen and a bookmark list. It is also what a web app manifest needs, which is why the set includes the Android sizes as well as the tab icons.

How it works

One square source image is rendered at 16, 32, 48, 180, 192 and 512 pixels, each cover-fitted to a square.
Every size is produced from the same source rather than resized from each other, so the small ones stay as clean as the source allows.
The set is zipped for download, ready to upload alongside a site.

What it cannot do

A detailed logo loses everything at 16 pixels. A single letter or a bold shape survives; a crest does not.
A non-square source is cover-fitted, which crops the sides — start from a square version of the mark.
No .ico file is produced, because current browsers accept PNG. An ancient system that insists on .ico needs a conversion step.
One image at a time; there is no batch mode for several brands.

Frequently asked questions

Why does a square source matter?

Because each icon is a square. A wide image is cover-fitted, which crops the sides, so a logo that runs to the edge loses part of itself. Start from a square version of the mark.

What is each size for?

16 and 32 are the browser tab. 48 is used by some desktop shortcuts and older Windows toolbars. 180 is Apple's touch icon. 192 and 512 are the Android/PWA sizes declared in a web app manifest.

Can I get a single .ico file?

This tool produces PNGs, which every current browser accepts as a favicon without an .ico. If an old system insists on .ico, one of the 16 or 32 PNGs can be converted, but it is rarely needed now.

Why does my icon look mushy in the tab?

Because a detailed logo shrunk to 16 pixels loses everything. Simplify the mark — a single letter, a bold shape, strong contrast — and generate again. This is the single most common reason a favicon looks bad.

Is my image uploaded?

No. Every size is rendered in your browser and zipped there, so nothing is transmitted.
