Why Use This Tool?
A favicon is the tiny icon sitting in the browser tab next to your page title. Websites expect it as an .ico file, and a proper one bundles several sizes — 16 px for the tab, 32 px for bookmarks, up to 256 px for shortcuts and app tiles. Building that by hand is a chore.
Drop a JPG here and the tool builds one .ico with all six standard sizes inside, scaled and centered automatically. It happens in your browser, so even a company logo that's under NDA stays on your machine.
How It Works
- Drop your JPG. A square image at 256 px or larger works best.
- Let the tool bundle sizes. It builds 16, 32, 48, 64, 128, and 256 px into one file.
- Download the .ico. Upload it to your site and link it as favicon.ico.
Frequently Asked Questions
What size should my source image be?
Square and at least 256 by 256 pixels gives the sharpest results. The tool scales down cleanly, but it can't invent detail that a tiny source never had.
Will a JPG favicon look good?
It looks fine, but JPG has no transparency, so a logo shot on white shows a white box in the tab. For a see-through background, convert from a PNG instead.
Where do I put the .ico file?
Upload it to your site root as favicon.ico, then add a link tag pointing to it in your page head. Browsers pick it up automatically in most cases.
Tips & Things to Watch
- Crop your image square first so nothing important gets trimmed by centering.
- Simple, bold shapes read best at 16 pixels — fine detail turns to mush.
- Test in a real browser tab after installing; cache can be stubborn, so hard-refresh.
