Favicon & App Icon Generator

Browsers and operating systems request favicons at different resolutions depending on context: the browser tab uses 16×16 or 32×32, iOS home screens request 180×180 for the Apple touch icon, and Android/Chrome PWA manifests specify 192×192 and 512×512 for the home screen and splash screen respectively. Providing all five sizes ensures crisp rendering in every context without browser upscaling artefacts.

A single square source image — ideally at least 512×512 pixels, with clear subject matter centred and not touching the edges — is enough to generate the full set. The generator downscales using Canvas bicubic interpolation, which produces sharp icons from photographic sources, logos, and illustrated marks alike. At 16×16 and 32×32, simplicity wins: intricate detail becomes a blur, so designs intended for small sizes should be bold and minimal.

All processing happens locally in your browser: no file is uploaded, no account is required. The resulting ZIP contains five PNG files named for their standard use cases, ready to drop into your project's public/ directory.
