Most social networks don’t let you format text, but they do accept any Unicode character. The Mathematical Alphanumeric Symbols block contains bold, italic and script versions of every letter, so text built from them looks bold wherever it is pasted.
How to use the Bold Text Generator
- Your text
Everything runs in your browser, so results appear instantly and nothing you type is sent to a server.
How it works
Type or paste your text; each bold style appears with a copy button.
Good to know
These styles are made from special Unicode characters, not fonts, so they keep their look when pasted into social media bios, chats and posts. Screen readers may read them letter by letter or skip them, so avoid them for important information. Everything is calculated in your browser, so nothing you type is sent to our server.
Formula
Each letter AโZ, aโz and digit 0โ9 is replaced by its counterpart in the Unicode Mathematical Alphanumeric Symbols block (U+1D400โU+1D7FF)
