LOVE ICONS
Love is the relationship set: hearts, couples, family groups and relationship marks, kept deliberately simple so they read as symbols rather than as pictures of particular people. That simplicity is the point, because a heart used as a favourite or a like control has to be recognised in a fraction of a second at the size of a fingertip. It is a small section, a few dozen icons rather than hundreds, so it covers the common cases well and unusual ones not at all. Each file is a transparent PNG that stays crisp from a small toolbar control up to a printed card, and it layers over a photograph or a brand colour without a pale square behind it. Product teams use them for favourites and saved items, dating and social apps for matches, and charities on donation pages. Wedding and family services use the couple marks. Free to download.
