Best for transparent logos
PNG is a strong source format for favicons because it can keep transparency, clean edges and UI-style graphics.

PNG-specific preparation
Preserve clean edges and transparency in your favicon
PNG is usually the safest raster source for logos because it supports alpha transparency and lossless edges.
Use real alpha transparency
Remove checkerboard or white backgrounds in the source editor. Only actual transparent pixels remain transparent in the ICO.
Leave a small safe area
Keep important artwork away from the outer edge so it does not feel cramped in browser tabs or rounded operating-system treatments.
Prefer a high-resolution source
A 256×256 or larger PNG gives the browser enough detail to generate the full set of smaller embedded icon sizes.

PNG to ICO questions
Does PNG transparency work in ICO?
Yes. Transparent PNG pixels can be preserved in the generated ICO output.
Should I use PNG or JPG for a logo favicon?
Use PNG for logos, text and transparent artwork. JPG is better suited to photographic sources without transparency.
Can a small PNG be enlarged?
It can be resized, but enlarging a small source does not create new detail. Start with at least 256×256 pixels when possible.
