Quick summary
You can bold text in a YouTube description by wrapping words with asterisks directly in the YouTube Studio description field. This method works in YouTube Studio and the bold formatting displays to viewers on the public video page.
Steps
- Sign in to studio.youtube.com and click Content in the left sidebar.
- Click the title or thumbnail of the video whose description you want to edit.
- In the Description field, wrap the text you want to bold with asterisks on each side — no spaces between the asterisks and the text.
- Click Save to publish the change.
- Open the video on youtube.com and expand the description to confirm the text appears bold.
