KR Heartfilled

KR Heartfilled font by Kat Rakos is a free decorative display typeface that looks like it’s doodled with a black gel pen and stuffed with cartoon hearts. Chunky, rounded letters are hollow in the middle, with bold outlines wrapped in looping hearts, dots, and curves that feel playful and hand-drawn rather than stiff or formal. It has an airy, coloring-book quality that makes every word feel like a little craft project.

Using KR Heartfilled, your text instantly turns into candy-sweet lettering for Valentine cards, kids’ party invitations, classroom posters, scrapbooking titles, stickers, and cheerful social media graphics. This free font shines at large sizes where the heart details can really breathe, while short phrases and names work best. Pair it with a clean sans serif in small text to keep things readable and let the decorative letters stay the star.
