Mastodon Line Breaker
A Mastodon line breaker keeps line breaks and paragraph spacing in your toots, which matters because limits vary by instance (often 500 characters). Lay out your lines and copy the result into the composer.
“Keep gaps” puts an invisible character on blank lines so platforms that strip empty lines still show the spacing.

What is the character limit on Mastodon?
It depends on the instance — the default is 500 characters, but some servers allow more. Line breaks count toward whatever limit your instance sets.
Why did my spacing change when I posted to Mastodon?
Pasting from other apps can collapse blank lines. This tool inserts an invisible separator so your spacing is preserved on any instance.
