Enhance your icon workflow 10x with the Nucleo app
Launch Web App
Download communication icons for chat apps, email clients, help desks, and social platforms. The collection covers speech bubbles, envelopes, paper planes, notifications, video calls, mentions, hashtags, attachments, and translation, in outline, fill, and duo styles for both product UI and marketing pages. Save them as SVG, copy them as React components, or customize them in the Nucleo web and desktop apps.
Here are 16 outline icons at 32px from Nucleo Core, a family drawn in outline and fill at 24, 32, and 48px. Message bubbles, envelopes, a paper plane, webcam, and hashtag suit inbox layouts, contact pages, social feeds, and team chat tools.
Chats, mail, video calls, and alerts are the core tabs of most messaging apps. Built on an 18px grid, Nucleo UI renders them as fill duo icons at 18px, where a lower-opacity second tone gives each tab bar item extra depth.
