The favicon is much smaller and more abstract
A favicon needs to stay recognizable at very small sizes.
That often means simpler shapes and more padding.
Reference
Not every square image is doing the same job.
A favicon, social avatar, and other square assets may look similar, but they serve different roles and need different review standards.
Useful for site launches, brand refreshes, and profile-asset cleanup.
Profile images carry more identity detail
A social avatar can hold more detail than a favicon source asset.
That changes the crop and background decision.
Separate the workflows early
Trying to make one square asset do every job usually weakens both.
It is better to prepare separate variants from the start.
