YouTube bold text generator
Native syntax for comments, Unicode styles for titles and descriptions: the complete picture of bold text on YouTube.
In YouTube comments and live chat you do not need this tool: YouTube has native formatting there. Wrap a word in asterisks for *bold*, underscores for _italic_, and hyphens for -strikethrough-. The Unicode styles below are for the places that syntax does not reach: titles, descriptions, and your channel name.
Works in: Video titles ยท Descriptions ยท Channel name ยท Community posts
YouTube is the rare network with real formatting, but only in comments and live chat, where *bold*, _italic_, and -strikethrough- syntax works natively. Titles, descriptions, and channel names have no formatting at all, so bold text there means Unicode styled characters, which is what this tool generates.
What to know before styling YouTube text
- Comments and live chat: wrap the word in asterisks (*word*) for bold, underscores for italic, hyphens for strikethrough. No converter needed.
- Titles and descriptions ignore that syntax and show the asterisks literally; a Unicode-styled word is the only way to make one stand out there.
- YouTube search matches plain text, and titles are the strongest ranking text you control. Styling a title trades searchability for decoration; usually a bad trade beyond one accent word.
- Channel names accept styled characters, and handle (@name) does not, same split as most networks.
Frequently asked questions
How do I bold a word in a YouTube comment?
Wrap it in asterisks: *word* renders bold when the comment posts. Underscores make _italic_ and hyphens make -strikethrough-. This is native YouTube behavior; no tool needed.
Can I use bold text in a YouTube title or description?
The asterisk syntax does not work there, so the only route is Unicode styled characters like the ones this page generates. Use them sparingly in titles: styled words are invisible to YouTube search.
Why does my *bold* show asterisks instead of bold text?
The syntax only works in comments and live chat. In titles, descriptions, and community posts, YouTube shows the asterisks literally; paste a Unicode-styled version instead.
