How to Write Bold Text on WhatsApp and Facebook

Have you seen people writing bold text on WhatsApp and Facebook? It is easy to do, but each app works differently. Let us understand how.

How to write bold or italic on WhatsApp

WhatsApp uses special characters for formatting:

• Bold: put an asterisk on each side — for example, *Hello* becomes bold
• Italic: underscores — for example, _Hello_
• Strikethrough: tildes — for example, ~Hello~

Bold text on Facebook and Instagram

The WhatsApp asterisks do not work in Facebook and Instagram posts. There, bold text uses special Unicode characters that look like normal letters but stay bold wherever you paste them.

The easiest way — Social Caption Formatter

Instead of doing all this manually, use our Social Caption Formatter:

1. Paste your text (from ChatGPT or anywhere).
2. Choose your platform — WhatsApp, Facebook or Instagram.
3. The tool applies the correct formatting automatically.
4. Copy it and paste it directly.

If your text is already bold, the tool detects that too.
