Bold Text Generator

Most social networks, chats and comment boxes don't let you format text, but they show any Unicode character, and Unicode has whole bold alphabets, made for mathematics: 𝐁𝐨𝐥𝐝, 𝗕𝗼𝗹𝗱, 𝑩𝒐𝒍𝒅 and more. The generator replaces every letter and digit of your text with its bold counterpart, so the text stays bold wherever you paste it: in an Instagram or TikTok bio, a post on Facebook or X, a YouTube comment, a Discord or WhatsApp message or a nickname. You see your text in seven styles at once: Bold, Bold sans-serif, Bold italic, Bold italic sans-serif, Bold script, Bold Fraktur and Double-struck.

Each style has its own Copy button. Latin letters and digits work in every style, and Greek letters in the first four. Letters with accents, such as é or ü, keep their accents. Unicode has no bold version of other alphabets, such as Cyrillic or Arabic, so their letters stay as they are, and the tool lists them under the result. Use bold text with care: some apps show these characters in another font, and screen readers may spell them out or skip them, so keep important information, such as a phone number or an address, in normal letters.
