## How to Post All Your Existing Instagram Posts to Facebook, TikTok, and Pinterest

Rebuilding your Instagram archive on Facebook, TikTok, and Pinterest from scratch, post by post, adds up to hours you probably don't have.

With [OneUp](https://www.oneupapp.io/)'s crossposting workflow feature, you can automatically send all your existing Instagram posts to Facebook, TikTok, and Pinterest — 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 **Instagram** Business or Creator account
- Your **Facebook** Page
- Your **TikTok** account
- Your **Pinterest** account

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

> **Platform tip:** TikTok's API only exposes video content, so static-image Instagram posts won't carry over to this 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 Instagram archive keeps flowing to Facebook, TikTok, and Pinterest without you lifting a finger. Get started at [oneupapp.io](https://www.oneupapp.io/).
