ANSWER

Quick answer

Use SVG for scalable browser rendering, a multi-resolution ICO with 16×16 and 32×32 frames for broad fallback support, a 48×48 or 96×96 PNG for raster and search contexts, a 180×180 Apple touch icon, and 192×192 plus 512×512 PNGs in the manifest.

The recommended set

Use SVG for scalable browser rendering, a multi-resolution ICO with 16×16 and 32×32 frames for broad fallback support, a 48×48 or 96×96 PNG for raster and search contexts, a 180×180 Apple touch icon, and 192×192 plus 512×512 PNGs in the manifest.

Favicon.now exports additional legacy sizes when compatibility matters, but it separates those from the modern core so teams can make an informed choice.

Why 48-pixel multiples matter

Google requires a square favicon of at least 8×8 and recommends larger than 48×48. A 48×48, 96×96, or 144×144 source aligns with that recommendation while leaving the browser room to downsample cleanly.

03

Design at 16, export at 512

Start with a large master, but judge the artwork at 16×16 and 32×32 throughout the process. Details that disappear there should be removed or exaggerated, not merely exported sharper.
