## Instant LinkedIn Carousels: Turn Blog Posts into Slide PDFs, Hands Off

Tired of manually chopping up blog posts into LinkedIn carousels? There’s a better way. With open, low-code automation tools and AI, you can trigger a workflow that turns any new blog post into a polished, ready-to-upload LinkedIn carousel PDF, automatically. Here’s how to do it (and what to watch for).

## What You Need

- Blog with RSS feed or webhook (WordPress, Ghost, Medium, etc.)

- n8n (free, open-source automation)

- OpenAI or Claude API for AI summarization

- Canva or Bannerbear API for image + slide generation

- Google Slides or PDF export capability (optional, for custom slides)

- Email or Slack for notifications

- LinkedIn account

## Step 1: Trigger When a Blog Post Publishes

- Connect RSS/Webhook to n8n: RSS Feed: Use the RSS Feed Read node. Paste your blog’s feed URL.

- Webhook: Use the Webhook node and have your blog ping it when publishing.

> Gotcha: Your RSS feed should provide full content, not just summaries.

## Step 2: AI Summarize for Carousel Slides

- Summarize and chunk with AI: Use n8n’s HTTP Request node to call OpenAI/Claude API.

- Prompt: “Summarize this blog post into 6-8 concise, actionable points for a LinkedIn carousel. Suggest a catchy title and a final CTA.”

- Parse the output into an array for slides.

> Pro Tip: Test and tweak your prompt for style and brevity.

## Step 3: Generate Slide Images and Layout

- Create visuals and layouts automatically: For each point, send the text to an image generator (e.g., DALL·E, Canva API).

- Use a service like Bannerbear, Canva, or Google Slides via Make/Zapier to combine text and image per slide.

- Set branding colors and fonts in your template for instant consistency.

> Gotcha: API rate limits and costs may apply. Add n8n error handling to retry or skip on failure.

## Step 4: Assemble and Export PDF

- Export slides as a PDF: Automate this with your chosen slide/image tool: Canva/Bannerbear: Use the API to generate and export PDF.

- Google Slides: Use Make/Zapier to assemble slides and export as PDF.

- Save the PDF for the next step.

> Pro Tip: Standardize your slide template for brand consistency and faster workflow.

## Step 5: Notify or Deliver

- Send the carousel for review or upload: Email the PDF to your team or yourself.

- Send a Slack or Teams message with the PDF.

- (Advanced) Use browser automation (e.g., AuthoredUp, Taplio, or Bardeen) to upload to LinkedIn, as direct API upload is unsupported.

> Gotcha: LinkedIn doesn’t allow direct PDF uploads via API, but browser-based automation or reminders work well.

## Platform Comparison Table

| Platform | Flexibility | Cost | AI Integration | Best For |
| --- | --- | --- | --- | --- |
| n8n | Very High | Free/Open Source | Full control with HTTP nodes | Custom, powerful automations |
| Make | High | Free & Paid | Many built-in AI modules | Visual, quick setup, mid-complexity |
| Zapier | Medium | Paid, limited free tier | Easy AI triggers/actions | Simple automations |
