How to repurpose a TikTok carousel for Instagram and LinkedIn
By Harmony Crafted · · 5 min read
A carousel you already made for TikTok is a ready-made asset for other platforms — but each one packages carousels differently. Here's what to know before you cross-post your own slides.
The limits at a glance
- TikTok: up to 35 photos per post (The Verge, TechCrunch).
- Instagram: up to 20 photos or videos per carousel, doubled from 10 in August 2024 (The Verge, TechCrunch).
- LinkedIn: carousels are shared as document posts. LinkedIn's Help Center says the file "cannot exceed 100MB and 300 pages" and supports PPT, PPTX, DOC, DOCX and PDF (LinkedIn Help).
Step 1: Get your original slides back
If your source files are lost, paste the post link into the CarouselStats downloader and use Download all (ZIP). The slides arrive numbered in order, which matters for the next steps.
Step 2: Instagram
- If your TikTok carousel has more than 20 slides, cut it down or split it into two posts.
- TikTok slides are often tall and full-screen; check how Instagram crops them in the preview and add padding if text sits near the edges.
- Rewrite the caption for Instagram rather than pasting TikTok hashtags.
Step 3: LinkedIn
- Combine the slides into a single PDF in order (most image viewers and design tools can export a multi-page PDF).
- On LinkedIn: Start a post → More → Add a document, choose the file, give it a title, add a description and post (LinkedIn Help).
- You can't swap the document after posting — only edit the description or delete the post — so proofread first (LinkedIn Help).
- Viewers can download your document as a PDF, according to LinkedIn Help, so don't include anything you wouldn't want saved.
- LinkedIn is more professional: lead with the takeaway, cut slang, and make the last slide a clear call to action.
Only repurpose what you own
Cross-posting your own carousels is smart reuse. Reposting another creator's carousel needs their permission — see the FAQ.
