Instagram Text Formatter: Bold, Italic and More
Style words for Instagram, check the character count and preview the post before you paste it. Nothing is sent anywhere.
The styled letters are Unicode characters, so they paste into any app. Screen readers may read them badly and search will not match them. Keep them for a few words, not whole posts, and not for hashtags, links or @mentions.
How to use the Instagram Text Formatter
- Type or paste your post into the box.
- Select the words to style and press Bold, Italic, Underline, Strikethrough or Monospace. With nothing selected, the style is applied to the whole text.
- Press the same button again to take the style off, or Plain to clear all of it.
- Check the character count and the preview, then press Copy text and paste it into Instagram.

Good to know
- Captions are cut after about two lines in the feed, followed by "more".
- The styled letters are Unicode characters, not real formatting. Screen readers may read them badly and search does not match them, so use them sparingly.
- Letters other than A to Z and digits are left as they are, so accented letters and non-Latin scripts are not styled.
Questions
Can I use bold or italic text in an Instagram caption?
Instagram does not offer text formatting. Styled Unicode letters work in captions, comments and the bio. Style the text here, press Copy and paste it into Instagram.
Will styled text show up in search and hashtags?
No. A hashtag made of styled letters is not the same word to Instagram, so it will not link or match. Keep hashtags, @mentions and links in plain text.
How do I get line breaks in an Instagram bio?
Type the line breaks here and paste the result. Instagram keeps blank lines pasted into the bio and captions.
Is my text sent to a server?
No. The styling runs in your browser and nothing is uploaded or saved.
