X Text Formatter: Bold, Italic and More

Style words for X, check the character count and preview the post before you paste it. Nothing is sent anywhere.

X130 / 280

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.

Good to know

  • X counts letters from the styled Unicode sets as two characters each, so a bold word uses up the limit twice as fast.
  • 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

Does bold text on X count extra toward the limit?

Yes. X counts most Latin letters as one, but the look-alike bold and italic letters fall outside that range and count as two. The counter here uses the same rule so you can see the real cost.

Is there a built-in bold button on X?

Longer posts on some accounts have rich text, but a normal post does not. Pasting styled Unicode letters works in any post, reply or bio.

Do links count toward the limit?

X shortens every link to a fixed length when it counts. This counter does not model that, so leave a little room if your post includes a link.

Is my text sent to a server?

No. The styling runs in your browser and nothing is uploaded or saved.
