How to Format Text on Instagram

Instagram doesn't offer built-in text formatting for captions, bios, or comments. There's no bold button, no italic option, no underline. But you can still format your text using Unicode characters — special character sets that render as bold, italic, or stylish fonts on any device.

This tool converts your regular text into Unicode equivalents. Type your caption, select a style, copy the result, and paste it directly into Instagram. The formatted text works everywhere — bios, captions, comments, Stories, and even DMs.

Available Text Styles

Bold Text

Use bold to emphasize key words in your captions. A bold call-to-action like "Save this post" stands out in a wall of text. Bold works great for headers in longer captions where you need to break up sections.

Italic Text

Italic adds emphasis with a softer feel than bold. Use it for quotes, product names, or phrases you want to highlight without shouting. Italic is popular in bios to add personality to taglines.

Stylish and Decorative Fonts

Script, serif, monospace, and other decorative fonts add visual variety. Use them sparingly — a stylish font in your bio headline grabs attention, but an entire caption in a decorative font is hard to read.

Best Practices for Instagram Text Formatting

• Use bold for CTAs: Make "Link in bio," "Save this," or "Share with a friend" stand out
• Keep it readable: Fancy fonts are eye-catching but harder to read. Use them for headers, not paragraphs
• Consider accessibility: Screen readers may not interpret Unicode fonts correctly. Don't use styled text for critical information
• Be consistent: Choose 1-2 formatting styles and stick with them across your posts for brand consistency
• Test on mobile: Always preview how your formatted text looks on a phone screen before posting

Frequently Asked Questions

How do I write bold text on Instagram?

Instagram has no built-in bold option. Use this text formatter to convert your text to bold Unicode characters, then copy and paste into your caption or bio. It works across all devices.

How do I italicize text on Instagram?

Like bold, Instagram doesn't support native italic. Use a text formatter to convert to italic Unicode characters, then paste into your caption, bio, or comment.

Do font styles work in bios and captions?

Yes. Unicode styles work in Instagram bios, captions, comments, and Stories. They also work on Facebook, Twitter, LinkedIn, TikTok, and most other platforms.

Will styled text affect my reach or SEO?

Using styled text sparingly is fine. Overusing fancy fonts can reduce readability and engagement. Screen readers also struggle with Unicode fonts, so keep the majority of text in standard formatting.
