Mastodon Line Breaker
Free Mastodon line breaker. Add real line breaks and blank-line spacing that survive when you paste into Mastodon, so your captions and bios keep their formatting instead of collapsing into one block.
Mastodon strips out the blank lines between paragraphs when you paste a caption, mashing everything into one wall of text. This Mastodon line breaker fixes that: it inserts an invisible character on each empty line so your spacing survives, giving your posts clean paragraphs, lists, and breathing room.
Write your caption with normal blank lines, click Add line breaks, then copy the result and paste it straight into Mastodon. Everything runs in your browser — nothing is uploaded. Mastodon's caption limit is about 500 characters, shown live as you format.
Frequently asked questions
Why do my Mastodon line breaks disappear?
Mastodon collapses consecutive blank lines. This tool puts an invisible character on each blank line so the spacing is preserved when you paste.
Does this work for Mastodon bios and comments too?
Yes — paste the formatted text anywhere Mastodon accepts text, including captions, bios, and comments.
Is my text uploaded anywhere?
No. The formatting happens entirely in your browser; your text never leaves your device.
