Bold Text Generator (copy & paste)
Bold letters that paste anywhere
Instagram, TikTok, X and Facebook do not let you format your bio, so the trick is to use Unicode's mathematical alphabet: characters that are genuinely bold or italic letters, not styled text, and therefore survive being pasted into a plain-text field. Type your text and this tool shows it in bold, italic, bold italic, bold sans-serif and monospace, each with its own copy button.
Because these are real characters, they work in usernames, messages and comments too, but for the same reason a screen reader will read them out oddly, so use them for flourish, not for whole sentences. Everything is generated in your browser. For a struck-through look, see the strikethrough text generator.
