Mastodon Post Formatter
A Mastodon post formatter cleans spacing, keeps line breaks, and adds Unicode bold or italic that Mastodon's plain-text composer has no styling for. Format your toot once and paste it into any instance.

Can I bold text in a Mastodon toot?
Mastodon's composer is plain text with no bold button, so the formatter substitutes Unicode bold characters that show up styled across instances.
Will Unicode formatting federate correctly?
Yes. Because it is plain Unicode rather than markup, styled text appears the same on whatever instance or app receives the federated post.
