How to post on multiple platforms at once.

Set up a workflow once and each new post on one app goes to the rest. The video also shows the other way: write one post in PostOnce and publish it everywhere.

  1. Connect the app you post on

    TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Bluesky, Pinterest or Threads.

  2. Add where it should go

    Pick one other account or all of them.

  3. Turn it on

    Post as usual. PostOnce sends each new post to the others.

Crossposting questions

What is crossposting?

Posting the same video, photo or post on more than one app. By hand, that means uploading again on each one; PostOnce does the uploads for you.

How do I post on all social media at once?

Connect the app you post on and the accounts it should go to, then turn the workflow on. Each new post goes to all of them.

Is there an app to post to all social media at once?

Yes. PostOnce posts to TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Bluesky, Pinterest and Threads. You post on one of them, and it sends the post to the rest.

Can I upload one video to multiple sites at once?

Yes. Upload it once, to TikTok, Instagram, YouTube or straight to PostOnce, and PostOnce uploads the same file to each of your other accounts.

Is it crosspost, cross-post or cross post?

All three are used and mean the same thing.

Can I post to all social media at once for free?

PostOnce is free for 7 days with no card. After that, plans start at $0.79 a day, billed yearly.

How do I automatically post on both Facebook and Instagram?

Connect either one as the source and the other as a destination. Meta's own setting shares Instagram posts to Facebook too; PostOnce adds the other apps.

Does crossposting hurt reach?

Not by itself, in our data. Across 40 customer YouTube channels, views showed no consistent drop after they started with PostOnce. PostOnce posts through each app's official posting API, like any scheduler, and uploads the file rather than a link. Brand-new or inactive accounts get few views either way.

Is crossposting the same as scheduling?

No. Scheduling sets when one post goes out. Crossposting sends a post you already made on one app to your other apps.
