How to Format Text on Facebook

Facebook gives you no formatting buttons for posts, comments or your bio. To make bold text on Facebook, you need special Unicode characters that look like bold, italic or styled letters. This Facebook text formatter does the conversion for you — just copy and paste the result anywhere on Facebook.

1

Type or paste

Enter the text you want to format into the editor above.

2

Select text

Highlight the words you want to style, or leave unselected to format all.

3

Pick a style

Click Bold, Italic, Strikethrough, or choose from the font dropdown.

Copy & paste

Click Copy, then paste into your Facebook post, comment or bio.

The live Facebook preview on the right updates as you type, so you can see exactly how your post will look — including the "See more" cutoff — before you publish. The formatter uses Unicode characters from the Mathematical Alphanumeric Symbols block: real text, not images or HTML, so it displays correctly on every device and in the Facebook mobile app.

Facebook Font Styles

8 styles in this free formatter. The Chrome extension adds 12+ more.

Italic

Why Format Your Facebook Posts?

Plain Facebook posts blend together. A bold hook and clean structure stop the scroll and lift engagement.

Stop the scroll

A bold first line grabs attention in a crowded News Feed before the "See more" cutoff.

Stand out in comments

Bold a key phrase in a comment or Group reply so it gets noticed and remembered.

Polish your Page & bio

Style your profile intro, Page description, and pinned posts for a professional look.

Sell on Marketplace

Make listing titles and event details scannable with bold headers and clean lists.

Frequently Asked Questions

How do I make bold text on Facebook?
Facebook has no bold button for posts or comments. To add bold text, use the Facebook Text Formatter above: type your text, select it, click Bold, then copy and paste it into your Facebook post, comment, or bio. It works because the tool converts your letters into Unicode bold characters that Facebook displays exactly as typed.
Does this formatting work in Facebook comments, bios and groups?
Yes. Because the output is plain Unicode text, it works anywhere you can type on Facebook — feed posts, comments, your profile bio and intro, Page descriptions, Group posts, Marketplace listings, and event descriptions — on both desktop and the mobile app.
Is this Facebook text formatter free?
Yes — completely free, with no sign-up, no limits and no watermark. The Post Formatter Chrome extension is free too and lets you format text inline on Facebook without copy-pasting.
Will the formatting show on the Facebook mobile app?
Yes. Unicode characters render the same on the Facebook iOS and Android apps as on desktop, because they are real text characters rather than images or HTML styling.
What is the Facebook post character limit?
A Facebook post can be up to 63,206 characters, but only the first ~477 characters show in the feed before a 'See more' link. Put your hook — and any bold text — near the start so it is visible before the cutoff.
Are there any downsides to Unicode text on Facebook?
A few: styled words are not searchable, screen readers may not read them correctly, and a handful of glyphs can look slightly different on older devices. Format key words and headlines rather than entire posts.
Can I use the same tool for LinkedIn, X and Threads?
Absolutely. The same Unicode text works on LinkedIn, X (Twitter), Threads, Bluesky, Instagram, YouTube and more. We have a dedicated formatter for each platform, and the Post Formatter extension formats inline on all of them.
