Butter Unsalted, by Gilles Pegel, is a free humanist sans-serif with a calm editorial feel. The letters pair broad, open curves with slim joins and clipped crossbars, so the font feels soft and modern at first glance but keeps a slightly literary rhythm that stops it from turning neutral.
It fits branding, magazine headings, book covers, poster titles, and packaging where you want a free font with a light, cultured voice rather than a blunt geometric tone. Because the curves stay generous while details turn crisp, it also works nicely for short pull quotes and title cards that need a quiet bit of character.
