Threads Text Formatter: Bold, Italic and More
Style words for Threads, 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 Threads 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 Threads.

Good to know
- Threads has limited built-in formatting, so styled letters are a common way to mark a few words.
- 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 bold text on Threads?
Threads has little formatting of its own. Styled Unicode letters paste into a post or reply and keep their look.
Is there a limit?
A post can hold 500 characters. The counter shows how much you have used.
Is my text sent to a server?
No. The styling runs in your browser and nothing is uploaded or saved.
