How to Bold Text on Facebook (Posts, Groups, and Comments)
Quick answer
If your Facebook editor shows formatting controls (like a bold button), use them for long posts or structured updates. If it doesn’t, the most reliable option is to convert your line into Unicode bold and copy‑paste it into any field. Unicode bold text behaves like normal text, so it stays bold even in plain‑text areas.
Method 1: Use native formatting (when available)
Some Facebook editors include formatting tools. When you see a toolbar, highlight your text and apply bold directly. This is best for longer posts, lists, and structured announcements.
Best for:
- Longer posts with headings
- Group announcements or rules
- Content that needs multiple sections
Method 2: Unicode bold copy‑paste (works everywhere)
When there is no bold button, use Unicode bold text. A generator replaces each letter with its bold Unicode equivalent, so the bold look stays visible in any text field.
Best for:
- Post hooks and first lines
- Short CTA lines (“Save this”, “Link in bio”)
- Comments or quick replies
- Bio or page headlines
