Resize image FAQ

What are common favicon dimensions?

16×16, 32×32, and 48×48 are the sizes people search for most. 32×32 is a solid default for tabs; Apple Touch uses 180×180.

Can one .ico hold multiple sizes?

Yes. Export as ICO from a large enough square source and ResizeImg packs 16, 32, and 48 into one favicon.ico.

Do I need different files for desktop and mobile?

Often yes: a small favicon for tabs plus a larger Apple Touch / PWA icon. Use the linked size pages for each.

Is my image uploaded?

No. Favicon resizing is local-only.
