How to Post to TikTok and Facebook at Once

TikTok and Facebook together give you access to 1B+ monthly active users and 3B+ monthly active users through different discovery mechanics. Publishing to both from a single upload maximizes reach without doubling the distribution workload.

Post to TikTok and Facebook simultaneously in 4 steps

1
Connect your TikTok and Facebook accounts
Go to the Connections page in Synchro and connect both accounts via OAuth. You only do this once — all future uploads use the same connections.
2
Upload your video file
From the Dashboard, click New Upload and select your video file. Synchro uploads it to cloud storage in the background while you fill in metadata.
3
Set your title and description
Fill in your title, description, and tags. These apply to both TikTok and Facebook by default — you can override per platform if needed.
4
Select TikTok and Facebook, then publish
Check both platforms in the selector and click Publish. Synchro uploads to each platform's official API simultaneously and gives you direct links when complete.

Frequently asked questions

Can I post the same video to TikTok and Facebook?

Yes. Most video content can be published to both platforms from a single file. The main consideration is format: TikTok recommends 9:16 (vertical) preferred while Facebook prefers 16:9 or 1:1 for feed videos. If you upload a landscape video to a vertical-first platform it will display with letterboxing. Synchro handles distribution to each platform simultaneously from one upload.

How long does it take to post to TikTok and Facebook at the same time?

With Synchro, the workflow takes 3–5 minutes: upload your video file, set your title and description, select both TikTok and Facebook, then publish. Synchro uploads to both platforms' APIs simultaneously — you do not wait for one upload to finish before the other starts.

Do I need a tool to post to TikTok and Facebook simultaneously?

You can upload manually to each platform, but that means two separate upload interfaces, filling in the same metadata twice, and waiting for each independently. A video distribution tool like Synchro handles both from a single upload — saving 15–30 minutes per video for creators publishing to multiple platforms regularly.
