TikTok and Instagram Reels are close enough in format that most creators end up making essentially the same video for both — which raises the obvious question of why you'd upload it to each platform separately at all. Once you set up an ongoing sync, you don't have to.

## How the sync works

Rather than migrating old videos, this workflow watches your TikTok account for anything new and automatically republishes it to Instagram as a Reel, continuously, without any manual re-uploading.

1. **Connect both accounts** — your TikTok account and your Instagram Business or Creator account — from the **Accounts** page in OneUp.
2. **Open the Crossposting menu** from the dropdown next to **Create a post**, and click **Add Workflow**.
3. **Set TikTok as your source account.**
4. **Set Instagram as your destination**, and confirm it's set to publish as a Reel rather than a standard feed video.
5. **Filter to video content** — TikTok's photo-mode carousels won't map to Reels the same way, so this workflow works best scoped to video specifically.
6. **Launch the workflow.** From here, every new TikTok video automatically publishes to Instagram as a Reel shortly after it goes live.

## Things worth adjusting before you turn this on

- **Watermarks** — if your TikTok exports carry a visible TikTok watermark, it's worth sourcing a cleaner export where possible so it doesn't look out of place as a Reel.
- **Captions and hashtags** — TikTok-specific references (trending sounds, "duet this," platform-specific slang) don't always translate well to an Instagram audience, so review whether your captions need adjusting for the new destination.

## Why creators set this up

Making a video once and having it land natively on two of the biggest short-form platforms, without manually repeating the upload process, is one of the more direct time-savers available to anyone posting short-form video regularly.
