One source, every icon surface
Renaming image.png to favicon.ico does not convert it. ICO is a container that can hold several raster sizes so older browsers, desktop shortcuts, and crawlers can choose the right layer. The generator encodes the ICO correctly and keeps the PNG source available for modern surfaces.
ICO layers
16, 32, and 48px
Best source
Square PNG, 512px+

ICO + full web icon kit
How to get a production-ready result
1Upload the PNG
Choose square artwork, ideally 512×512 or larger. Transparency is preserved unless you select a background.
2Generate the layers
The resulting favicon.ico contains the small sizes that need pixel-level clarity rather than a renamed PNG payload.
3Keep the modern files too
Install the ICO fallback together with PNG, Apple touch, PWA, and manifest assets for complete coverage.
Common questions
Can I rename a PNG to favicon.ico?
No. The extension changes but the file remains PNG data. A real ICO must be encoded as an icon container, ideally with multiple embedded sizes.
Which sizes belong inside favicon.ico?
16×16 and 32×32 are the essential browser sizes; 48×48 is a useful desktop and legacy fallback.
Do modern sites still need favicon.ico?
Yes as a resilient root fallback for older browsers, crawlers, and clients that request /favicon.ico without reading your HTML.
