How to Post All Your Existing Instagram Posts to Pinterest, TikTok, and Threads
Rebuilding your Instagram archive on Pinterest, TikTok, and Threads from scratch, post by post, adds up to hours you probably don't have.
With OneUp's crossposting workflow feature, you can automatically send all your existing Instagram posts to Pinterest, TikTok, and Threads — 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 Pinterest account
- Your TikTok account
- Your Threads account
Follow the OAuth prompts to authorize each one.
Step 2: Open the Crossposting Menu
- From the top navigation dashboard in OneUp, hover over the dropdown next to Create a post.
- Select Crossposting.
Step 3: Build Your Auto-Post Workflow
- Click Add Workflow.
- Set Instagram as your source account (the platform you're posting from).
- Under content type, choose the post types you want carried over.
- Select Pinterest, TikTok, and Threads as your destination accounts.
Platform tip: TikTok's API only exposes video content, so image-only 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?
Copying your existing Instagram posts over to Pinterest, TikTok, and Threads manually means opening each post, saving the media, and re-uploading it — repeatedly. OneUp skips all of that. It's a one-time setup that keeps paying off every time you add new Instagram content.
