Free Caption Formatter for Instagram and LinkedIn

Free caption formatter. Clean up line breaks, spacing, sentence case, and quotes in Instagram and LinkedIn captions right in your browser.

How it works

  1. Paste a draft caption.
  2. Apply one or more formatters.
  3. Copy the result into PostPublish or any composer.

Messy drafts slow down publishing

Captions copied from Docs, Slack, or email often arrive with odd spacing, straight quotes mixed with curly ones, and accidental blank lines. That noise shows up on mobile feeds and makes a careful brand look unfinished. Cleaning format is a different job from rewriting voice — and it should stay that way.

What this formatter changes

Paste a draft and apply passes for trim, sentence case, smart quotes, and collapsed blank lines. The tool does not invent new sentences, swap synonyms, or “optimize” your hook. It only normalizes spacing, case, and quotes so the words you already chose read cleanly on Instagram, LinkedIn, and the rest.

A simple pre-publish habit

Run the formatter after the creative pass and before the character check. Keep an original paste nearby if you want to compare; browser undo works in the text box, and nothing is stored on a server. Use it for client drafts you inherit mid-week as much as for your own writing.

Format once, schedule everywhere

Clean captions still need a queue, review, and publish path. PostPublish is built for that handoff: draft or paste the cleaned copy, review, and schedule across Instagram, Facebook, LinkedIn, Threads, X, and Telegram without reformatting in six composers.

FAQ

Will this rewrite my voice?

No. It only changes spacing, case, and quotes. It does not invent new copy.

Can I undo a pass?

Use your browser undo in the text box, or paste the original again. Nothing is stored.
