How it works
This bold text copy and paste page swaps each letter and number for a bold mathematical character, so the weight survives a paste. It holds 230 characters and no bold comma. Some apps strip or block these characters, and screen readers may read them badly.

Two bolds, then two that lean
The large card sets your line in Bold sans, which has no feet. Bold serif sits below, with feet. Then come Sans bold italic and Bold italic, for a line that is heavy and leaning at once. Each row has its own copy button.
Why the full stop stays light
Unicode's table of mathematical styles gives bold three things: Latin letters, Greek letters and digits. Punctuation is not on the list, so every full stop, comma and question mark stays as typed. The grid ends with six heavy marks to copy by hand, an exclamation mark among them. Unicode names no heavy question mark.
Tips
- If the text around it has no feet, Bold sans passes for real bold. Bold serif looks like a book that wandered in.
- Typed Greek goes bold too, Ï and Ω included. Bold is also the only style with a digamma, a letter Greek dropped.
Questions and answers
Is this a bold text font?
No: this is a bold text converter, and no font is involved. Each letter is swapped for a separate character, such as Mathematical sans-serif bold capital A, U+1D5D4, in Unicode since March 2001. The grid under the tool names all 230.
How do I make text bold where there is no bold button?
Copy a row and paste it: the weight is in the characters, so no button is needed. In a box that does format, Wikipedia's table of keyboard shortcuts gives Ctrl+B or Cmd+B, and Markdown takes two asterisks each side.
Can it make bold numbers?
Yes. Five of Unicode's mathematical styles have digits and two of them are bold, so Bold sans and Bold serif turn the 2 and the 3 in the sample. No italic style has digits, so the two leaning rows keep numbers light.
