Social Post Previewer
Write a draft, choose a reference platform, and review a neutral card preview with local character counts. This tool does not connect to or publish on any platform.
A QUICK WALKTHROUGH
How to use this tool
- Enter post text, an optional author name, and an image URL for the card.
- Choose a platform reference to see its character guidance and remaining count.
- Edit the draft until the card and count look right, then copy it into the platform you control.
Local draft preview
Post text and optional fields stay in this browser. No login, upload, scraping, API call, scheduling, or publishing is involved.
Platform references
The listed limits are editorial reference values: X 280, Facebook 63206, LinkedIn 3000, Instagram caption 2200, and TikTok 4000 characters. They are not a live platform validator.
GOOD TO KNOW
Common questions
Will this publish my post?
No. It only previews and counts the draft locally; copy or paste it into the destination app yourself.
Are these exact platform limits?
No. They are reference guidelines, not a guarantee of what a current account, format, or platform will accept.
