Here's what you can format in an Instagram caption, and how.
What is an Instagram caption formatter?
An Instagram caption formatter is a tool that styles a caption before you post it: bold and italic words, and line breaks that Instagram keeps.
Instagram has no formatting buttons of its own. This formatter uses Unicode letters for bold and italic, and an invisible character to hold blank lines.
How to format an Instagram caption
What you can format
| Format | How it works |
|---|---|
| Letters swapped for bold Unicode letters | |
| Letters swapped for italic Unicode letters | |
| An invisible character holds each empty line |
Accents stay with their letters, and hashtags and mentions stay plain, so they still work. Screen readers can read styled letters oddly, so keep them to a few words.
Instagram's caption limits
A caption can be up to 2,200 characters, per Meta's Instagram API reference, with up to 5 hashtags since December 18, 2025. The counter checks both as you type.
For line breaks alone, use the Instagram line break generator.
