How to post to all social media at once (free and paid)

Some platforms can share to their sister apps automatically:

• Instagram can share posts, Reels, and Stories to a linked Facebook Page. Link the accounts in Meta's Accounts Center, then use the Share to Facebook toggle when you post.
• Threads posts can share to Instagram and Facebook feeds from the Threads app.

The limit is the family wall. Meta apps share with Meta apps. Nothing built-in sends your post to YouTube, TikTok, LinkedIn, or X.

If you post everywhere by hand, a little system saves real time:

• Write the caption once in a notes app, then paste it into each app.
• Export your video once in vertical (9:16). It works on Instagram Reels, TikTok, YouTube Shorts, and Facebook Reels.
• Do all platforms in one sitting instead of spreading them through the day.

This is free and it works. The cost is your evening, every time, and it is easy to skip platforms when you are tired. That skipping is how consistency dies.

A scheduler is one composer wired to every platform. In Unbusied:

• Write the post once and attach your photo or video.
• Select all your platforms: Instagram, Facebook, Threads, YouTube, TikTok, LinkedIn, and X (Twitter).
• Tweak any caption per platform if you want. A shorter one for X, a title for YouTube.
• Pick the time. Everything publishes on schedule, and you get an alert with a one-tap retry if a platform ever fails.

One honest note: posting the exact same thing everywhere is not always ideal. The good schedulers let you adjust per platform without starting over, so one idea fits each place it lands.
