Generate favicons from an image

Generate a practical website icon pack from one JPG, PNG, or WebP image without uploading your brand asset. FileGizmo creates 16, 32, and 48 pixel browser favicons, a 180 pixel Apple touch icon, and 192 and 512 pixel Android icons. All six PNG files arrive in one ZIP archive with recognizable filenames.

The source image is scaled proportionally and centered inside transparent square canvases, so a non-square logo is not stretched. For the sharpest small icons, begin with a simple high-resolution mark that remains readable at 16 pixels. This tool intentionally generates modern PNG assets and does not mislabel PNG data as a legacy .ico file.

Rendering and ZIP creation happen inside a dedicated browser worker. Your logo stays on your device, and no account is required. Add the generated assets to your public website directory and reference the appropriate browser, Apple, and web-app icons in your page metadata or application manifest.

One source image becomes the sizes browsers and phones actually request: the small icons a desktop browser shows in a tab and a bookmark, the larger Apple touch icon iOS uses when a site is added to a home screen, and the Android icons a web manifest points at. Producing them by hand in an image editor is tedious and easy to get subtly wrong.

Start from a square image at 512 pixels or larger. Anything smaller has to be enlarged to make the biggest icon, and an upscaled logo looks soft exactly where it is most visible. A non-square image is fitted rather than stretched, but a square source gives a predictable result.

Simple shapes survive the small sizes. At sixteen pixels a wordmark is unreadable and fine detail turns to mush, which is why most recognisable favicons are a single letter, a symbol, or a bold silhouette. It is worth looking at the smallest output before committing to a design.

Every size is generated on your device. An unreleased brand is one of the more sensitive things a small company owns, and uploading a logo to a generator means handing a copy to whoever runs it, often weeks before the launch it belongs to.
