How bold text works
Most apps strip formatting when you paste, but they keep characters. Unicode’s Mathematical Alphanumeric Symbols block contains complete bold alphabets — serif, sans-serif, and italic versions of both — with digits for the upright styles. This generator swaps each letter for its bold counterpart, so the weight comes along wherever the text goes.
The Typeface chips let you compare serif and sans at a glance, or show only the bold italic styles. Bold Gothic and Bold Script are included for when you want weight with more character.
For emphasis inside a sentence, switch “Make bold” to “Only marked words”. Wrap the words you want in double asterisks — the same way Discord and many editors mark bold — and the rest of the line stays in normal letters. It’s the closest thing to real bold formatting in a plain-text box, and it keeps longer posts readable. UPPERCASE works well for short headlines; long bold sentences are harder to read than plain ones.
About search: Bold math letters are among the best-supported styled characters, but search and hashtags won’t match them. Keep hashtags and keywords in plain letters.
Frequently asked questions
How do I make text bold on Instagram?
Instagram has no bold button, so type your text here, copy Bold Sans or Bold Serif and paste it into your bio or caption. The bold letters are Unicode characters that keep their weight after pasting.
Can I bold just one word?
Yes. Switch “Make bold” to “Only **marked** words” and wrap the words in double asterisks, like **this**. Everything else stays plain, which reads better than a fully bold paragraph.
Serif or sans — which bold should I use?
Bold Sans looks like the interface text of most apps and blends in cleanly. Bold Serif has small feet on the letters and feels more formal. Both include bold digits.
Does bold text affect accessibility?
Screen readers may announce each bold letter as a mathematical symbol or skip it. Use bold Unicode for a word or two of emphasis, not for whole paragraphs or important instructions.
