Not everyone needs a full personal site. Many people only need a simple personal landing page: who you are and where to go next.
That is what a good bio link is. One URL for Instagram, résumés, email signatures, and conference slides.
1kb.bio gives you that page in minutes. Minimalists, authors, entrepreneurs, and freelancers use it when they want one calm place for all their links.
See a sample designer link in bio page — with a profile photo and the same simple layout you get on 1kb.bio.
