Bold text generator

Make text bold in places that have no bold button, such as Instagram captions, LinkedIn posts, X and app bios. Type your text, then copy the serif, sans-serif or italic bold version and paste it into your post.

How to use it

  1. Type your text

    Type or paste the words you want to style. Every style below changes as you type.

  2. Pick a style

    Look through the styles and choose the one that suits your bio, caption or message.

  3. Copy and paste

    Select Copy next to the style, then paste the text where you want it and check how it looks there.

Bold without a bold button

Most social apps strip formatting, so text you make bold in a document arrives plain. Unicode includes complete bold alphabets for mathematical writing, and the generator swaps your letters for those characters, so the bold survives the paste.

Choose sans bold for a modern look that matches most app fonts, serif bold for a classic headline, and bold italic when you want a word to stand out in a sentence.

Good places for bold text

Use bold sparingly. A whole paragraph in bold is harder to read, and screen readers may spell out the special characters or skip them.

  • A first line in a LinkedIn or Facebook post that should catch the eye.
  • Section headings in a long Instagram caption or a thread on X.
  • A product name or an offer in a shop bio.
  • One key word in a message, instead of writing it in capitals.

What stays plain

Bold covers the letters A to Z and the digits 0 to 9. Accented letters, punctuation, emoji and other alphabets stay as you typed them, so a word with an รฉ will mix bold and plain letters.

Search inside most apps matches only plain letters, so people searching for a bold word may not find it. Keep names, hashtags and links in plain text.

Frequently asked questions

How do I make text bold on Instagram?

Instagram has no bold option, so type your text above, copy the bold version and paste it into your caption, bio or comment. The bold letters are special characters, so they stay bold after you post.

Can I use bold text on LinkedIn?

Yes. LinkedIn posts have no formatting, but bold Unicode letters paste in and stay bold. Use them for a first line or a few headings. Search on LinkedIn matches plain text, so keep names and keywords you want found in plain letters.

Why do numbers and accents stay plain in some styles?

Each style only has the characters Unicode includes. Serif bold, sans bold and double-struck include digits, while the italic styles do not, and no style includes accented letters. Those characters stay as you typed them.

Is the bold text generator free?

Yes. It runs in your browser, with no sign-in and nothing to install. Your text never leaves your device, so you can try as many versions as you need.
