LinkedIn Carousel Creator

Create stunning LinkedIn carousel posts as PNG images. This skill generates styled HTML slides optimized for square format (1080×1080px), then automatically screenshots each slide for direct upload to LinkedIn.

Core Philosophy

1. LinkedIn-First Design — Square format (1080×1080px), optimized for mobile feed viewing
2. Informational Content — Tips, workflows, lists, frameworks (not presentations)
3. Consistent Styling — Reuse proven design systems from frontend-slides
4. Automated Export — Generate HTML → Screenshot → PNG files ready for LinkedIn
5. Viewport Perfect — Every slide must fit exactly in 1080×1080px without scrolling

LinkedIn Carousel Specs

Format: Square (1080×1080px)

• Aspect ratio: 1:1
• File format: PNG (recommended) or JPG
• File size: Under 10MB per image
• Max slides: 10 images per carousel
• Ideal slide count: 5-8 slides (best engagement)

Content Structure:

1. Cover slide — Hook + title + your brand
2. Content slides — One key point per slide (3-6 slides)
3. Closing slide — CTA / summary / follow prompt

---

When to Use This Skill

Use for LinkedIn carousel posts like:

• "5 AI GTM workflows you should be using"
• "How to build X: A step-by-step guide"
• "7 mistakes founders make with Y"
• "The complete framework for Z"
• "Before & After: How we 10x'd our metrics"

NOT for:

• Long-form presentations (use frontend-slides)
• Video content
• Single-image posts

Workflow Overview

1. Content Input → User provides topic/outline
2. Style Selection → Choose visual style (or preview options)
3. HTML Generation → Create 1080×1080px HTML slides
4. Screenshot → Auto-capture each slide as PNG
5. Delivery → Folder of PNG files ready for LinkedIn upload

---

Phase 1: Content Discovery

Step 1.1: Get Topic & Structure

Ask the user:

Question 1: What's the topic?

• Header: "Topic"
• Question: "What's the main topic of this carousel?"
• (Free text input)

Question 2: Content Type

• Header: "Format"
• Question: "What type of post is this?"
• Options:
  • "Numbered list" — "5 ways to...", "7 mistakes...", "3 steps to..."
  • "How-to guide" — Step-by-step tutorial or process
  • "Framework" — Concept explanation with structure
  • "Before/After" — Transformation or case study
  • "Insights/Tips" — Collection of advice or learnings

Question 3: Slide Count

• Header: "Length"
• Question: "How many slides?"
• Options:
  • "Short (5-6)" — Quick, punchy (best for mobile scrolling)
  • "Medium (7-8)" — Standard carousel length
  • "Long (9-10)" — Maximum LinkedIn allows

Question 4: Branding Handle

• Header: "Brand"
• Question: "What handle or name should appear on each slide?"
• (Free text input — e.g., "@yourhandle", "Acme Inc", or leave blank for none)

Question 5: Content Ready?

• Header: "Content"
• Question: "Do you have the content written?"
• Options:
  • "Yes, I have all content" — Paste it in
  • "I have bullet points" — Need light formatting
  • "Just the topic" — Need help outlining

If user has content, ask them to share it.

Content Density Rules for LinkedIn

Each slide should be scannable in 2-3 seconds on mobile:

Slide Type	Max Content
Cover	Title (1 line) + subtitle (1 line) + branding
List item	Number/icon + heading (2 lines max) + body (3 lines max)
Framework	Diagram/visual + 2-4 labels
Quote/Stat	1 large stat or quote + context
CTA	1 action + visual element

If content exceeds limits: Break into multiple slides or simplify.

---

Phase 2: Style Selection

Users can choose styles two ways:

Option A: Direct Selection (Faster)

Show preset picker:

Question: Pick a Style

• Header: "Style"
• Question: "Which visual style works best for your content?"
• Options:
  • "Bold Signal" — High-contrast card on dark, confident
  • "Dark Botanical" — Elegant dark with soft abstract shapes
  • "Notebook Tabs" — Editorial cream paper with colorful tabs
  • "Pastel Geometry" — Friendly pastels with decorative pills
  • "Neon Cyber" — Futuristic tech aesthetic
  • "Split Pastel" — Playful two-tone split design

(See STYLE_PRESETS.md for full details on each style)

Option B: Guided Discovery

If user isn't sure, ask:

Question: Audience & Tone

• Header: "Vibe"
• Question: "Who's your audience and what tone?"
• Options:
  • "Professional/Corporate" → Recommend: Bold Signal, Dark Botanical
  • "Creative/Playful" → Recommend: Split Pastel, Pastel Geometry
  • "Technical/Dev-focused" → Recommend: Neon Cyber, Terminal Green
  • "Elegant/Premium" → Recommend: Dark Botanical, Paper & Ink

Then generate 2-3 preview slides and let user pick.

Phase 3: Generate HTML Carousel

File Structure

All carousel files (HTML source and PNG exports) are saved to the shared assets directory.

[carousel-name]/
├── index.html              # Full carousel (all slides)
├── slides/
│   ├── slide-01.html       # Individual slide pages
│   ├── slide-02.html
│   └── ...
└── exports/
    ├── slide-01.png        # Screenshots (generated in Phase 4)
    ├── slide-02.png
    └── ...

Phase 4: Screenshot Generation

After generating HTML, automatically capture screenshots.

Using Playwright (Recommended)

Create a Node.js script to screenshot each slide:

// screenshot-slides.js
const { chromium } = require("playwright");
const path = require("path");
const fs = require("fs");

async function screenshotSlides(slidesDir, outputDir) {
  const browser = await chromium.launch();
  const page = await browser.newPage();

  // Set viewport to LinkedIn carousel size
  await page.setViewportSize({ width: 1080, height: 1080 });

  // Ensure output directory exists
  if (!fs.existsSync(outputDir)) {
    fs.mkdirSync(outputDir, { recursive: true });
  }

  // Find all HTML files in slides directory
  const slideFiles = fs
    .readdirSync(slidesDir)
    .filter((f) => f.endsWith(".html"))
    .sort();

  console.log(`Found ${slideFiles.length} slides to screenshot`);

  for (const slideFile of slideFiles) {
    const slidePath = path.join(slidesDir, slideFile);
    const outputName = slideFile.replace(".html", ".png");
    const outputPath = path.join(outputDir, outputName);

    console.log(`Capturing ${slideFile}...`);

    await page.goto(`file://${path.resolve(slidePath)}`);

    // Wait for fonts and animations
    await page.waitForTimeout(500);

    // Take screenshot
    await page.screenshot({
      path: outputPath,
      type: "png",
      fullPage: false,
    });

    console.log(`✓ Saved ${outputName}`);
  }

  await browser.close();
  console.log("\n✨ All slides captured!");
}

// Usage
const carouselName = process.argv[2];
if (!carouselName) {
  console.error("Usage: node screenshot-slides.js <carousel-name>");
  process.exit(1);
}

const slidesDir = path.join(__dirname, carouselName, "slides");
const outputDir = path.join(__dirname, carouselName, "exports");

screenshotSlides(slidesDir, outputDir);

Installation

The skill directory needs these dependencies:

{
  "name": "linkedin-carousel-screenshots",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "playwright": "^1.40.0"
  }
}

First time setup:

cd /path/to/skills/create-html-carousel
npm install

Running Screenshot Script

After generating HTML slides:

node screenshot-slides.js carousel-name

This will:

1. Open each slide HTML in a headless browser
2. Set viewport to 1080×1080px
3. Wait for fonts/animations to load
4. Capture PNG screenshot
5. Save to [carousel-name]/exports/

---

Phase 5: Delivery

After screenshots are generated, present to user:

✨ Your LinkedIn carousel is ready!

📁 Location: /assets/carousel-name/

**Slides:**
- 6 HTML slides in slides/ folder
- 6 PNG images in exports/ folder (1080×1080px)

**Preview:**
Open index.html to see all slides with navigation.

**Upload to LinkedIn:**
1. Create new post on LinkedIn
2. Click "Add media"
3. Upload all PNGs from exports/ folder in order
4. Add your post copy
5. Publish!

**File sizes:**
- slide-01.png: 234 KB ✓
- slide-02.png: 198 KB ✓
- slide-03.png: 256 KB ✓
(All under 10MB limit)

Style Adaptation for Square Format

All styles from frontend-slides work for carousels, but require these adjustments:

Typography Scaling

Square format has less horizontal space, so scale fonts:

Element	Presentation (16:9)	Carousel (1:1)
Title	clamp(2rem, 6vw, 5rem)	72px (fixed)
Subtitle	clamp(1.25rem, 3vw, 2.5rem)	36px (fixed)
Body	clamp(0.875rem, 1.5vw, 1.125rem)	28px (fixed)
Small	clamp(0.75rem, 1vw, 0.875rem)	20px (fixed)

Why fixed sizes? We're targeting a single export size (1080×1080px), not responsive web viewing.

Layout Adjustments

Vertical space is precious:

• Reduce top/bottom padding (80px instead of 4rem)
• Tighter line-height (1.2-1.4 instead of 1.5-1.6)
• Fewer list items per slide (max 3-4)
• Smaller decorative elements

Mobile-first mindset:

• Most LinkedIn users view on phones
• Text must be readable at thumbnail size
• High contrast is critical
• Bold, simple layouts beat intricate designs

---

Content Best Practices

Hook Formula (Cover Slide)

Strong hooks for LinkedIn carousels:

• Number + Promise: "5 workflows that 10x'd our outbound"
• Contrarian: "Stop doing X. Do this instead."
• Before/After: "How we went from X to Y in 30 days"
• Question: "Why are only 3% of founders doing this?"
• Curiosity gap: "The GTM strategy nobody talks about"

Body Slides (Items 2-9)

Each slide should:

1. One clear point — Don't cram multiple concepts
2. Visual hierarchy — Large number/icon + heading + body
3. Concrete, not abstract — "Use job postings to find intent" not "Leverage signals"
4. Scannable — 2-3 second read time max

Closing Slide

Always include a CTA:

• "Follow for more [topic]"
• "Repost if this helped"
• "Comment your biggest takeaway"
• "DM me if you want the full playbook"

Avoid:

• "Link in comments" (often gets buried)
• "Check out my website" (feels salesy)
• No CTA at all (wasted opportunity)

---

Troubleshooting

Fonts Not Loading in Screenshots

Symptom: Screenshots show default system fonts

Solution:

1. Use web-safe fonts (Arial, Georgia) OR
2. Add await page.waitForLoadState('networkidle') before screenshot
3. Increase wait timeout: await page.waitForTimeout(1000)

Screenshots Are Blurry

Symptom: Text looks fuzzy or low-res

Solution:

1. Set device scale factor in Playwright:

   await page.setViewportSize({
     width: 1080,
     height: 1080,
     deviceScaleFactor: 2, // Retina-quality
   });
   

Content Overflows the Slide

Symptom: Text or elements cut off in screenshot

Solution:

1. Reduce font sizes
2. Decrease padding
3. Split into multiple slides
4. Simplify content (fewer bullets, shorter text)

Colors Look Different in Export

Symptom: PNG colors don't match HTML preview

Solution:

• Ensure browser color profile matches sRGB
• Use hex colors, avoid CSS filters that may render differently
• Test screenshot script before generating all slides
