Favicon (full set)

16 32 180 512

SVG + 16/32/48 + 180 + 192/512 Square format 1:1

This is the small icon in the browser tab. Use SVG + 16/32/48 + 180 + 192/512, so it looks right and loads fast.

This size is a hard convention: change it and something gets cropped or looks off.

For whoever builds the site

The 2026 set: favicon.svg (infinite scale, dark mode support) + multi-size favicon.ico (16/32/48) + apple-touch-icon.png 180×180 + manifest 192 and 512. Each system requests its size by exact name. In WordPress just upload a square ≥512×512 and it generates the rest.
