## How to Post All Your Existing TikTok Videos to Instagram, Facebook, and YouTube

Getting your TikTok history onto Instagram, Facebook, and YouTube usually means a lot of repetitive copy-paste work — unless you automate it.

With [OneUp](https://www.oneupapp.io/)'s crossposting workflow feature, you can automatically send all your existing TikTok videos to Instagram, Facebook, and YouTube — spaced out over time so they don't all publish at once.

* * *

**Step 1: Connect Your Social Media Accounts**

Head to the **Accounts** page in OneUp and make sure you've linked:

- Your **TikTok** account
- Your **Instagram** Business or Creator account
- Your **Facebook** Page
- Your **YouTube** channel

Follow the OAuth prompts to authorize each one.

* * *

**Step 2: Open the Crossposting Menu**

1. From the top navigation dashboard in OneUp, hover over the dropdown next to **Create a post**.
2. Select **Crossposting**.

* * *

**Step 3: Build Your Auto-Post Workflow**

1. Click **Add Workflow**.
2. Set **TikTok** as your source account (the platform you're posting _from_).
3. Under content type, choose the post types you want carried over.
4. Select **Instagram**, **Facebook**, and **YouTube** as your destination accounts.

> **Platform tip:** Instagram Business or Creator accounts are required for crossposting — personal accounts can't be used as a source or destination.

* * *

**Step 4: Configure Timing & Finalize**

Choose how much time to leave between each post so they trickle out instead of publishing all at once. Then click **Create Workflow**.

**Why Use OneUp for Crossposting?**

Once it's set up, your TikTok archive keeps flowing to Instagram, Facebook, and YouTube without you lifting a finger. Try it at [oneupapp.io](https://www.oneupapp.io/).
