Design high-engagement carousel posts via inference.sh CLI.

Quick Start

curl -fsSL https://cli.inference.sh | sh && infsh login

# Generate a carousel slide
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1080px;background:#0f172a;display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white;text-align:center\"><div><p style=\"font-size:24px;color:#818cf8;text-transform:uppercase;letter-spacing:3px\">5 Rules for</p><h1 style=\"font-size:64px;margin:16px 0;font-weight:900;line-height:1.1\">Writing Headlines That Convert</h1><p style=\"font-size:22px;opacity:0.5;margin-top:24px\">Swipe →</p></div></div>"
}'

Platform Specs

PlatformDimensionsSlidesAspect Ratios
Instagram1080 x 1080 pxUp to 201:1 (default), 4:5, 16:9
LinkedIn1080 x 1080 px or 1080 x 1350Up to 201:1, 4:5
Twitter/X1080 x 1080 pxUp to 41:1, 16:9
Facebook1080 x 1080 pxUp to 101:1, 4:5

Use 1080 x 1350 (4:5) on Instagram and LinkedIn — takes up more screen real estate in the feed than square.

Carousel Structure

The 7-Slide Framework

SlidePurposeContent
1HookBold claim, question, or promise — stops the scroll
2ContextWhy this matters, set up the problem
3-6ValueOne point per slide, numbered
7CTAFollow, save, share, comment, visit link

Slide 1: The Hook

The most important slide. If this fails, nobody swipes.

Hook TypeExample
Bold claim"90% of landing pages make this mistake"
Question"Why do your ads get clicks but no conversions?"
Number + promise"7 Python tricks I wish I learned sooner"
Contrarian"Stop writing blog posts (do this instead)"
Before/afterShow transformation
# Hook slide
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1350px;background:linear-gradient(180deg,#1e1b4b,#312e81);display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white;text-align:center\"><div><h1 style=\"font-size:72px;font-weight:900;line-height:1.15;margin:0\">90% of Landing Pages Make This Mistake</h1><p style=\"font-size:28px;opacity:0.6;margin-top:32px\">Swipe to find out →</p></div></div>"
}'

Slides 2-6: Content Slides

One point per slide. Never cram multiple ideas.

# Content slide template
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1350px;background:#1e1b4b;padding:80px;font-family:system-ui;color:white;display:flex;flex-direction:column;justify-content:center\"><div><p style=\"font-size:120px;font-weight:900;color:#818cf8;margin:0;line-height:1\">01</p><h2 style=\"font-size:48px;margin:24px 0 16px;font-weight:800;line-height:1.2\">Your headline is too vague</h2><p style=\"font-size:26px;opacity:0.8;line-height:1.6\">\"Welcome to our platform\" tells the visitor nothing. Lead with the outcome: \"Ship docs in minutes, not days.\"</p></div></div>"
}'

Slide 7: CTA Slide

# CTA slide
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1350px;background:linear-gradient(180deg,#312e81,#1e1b4b);display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white;text-align:center\"><div><h2 style=\"font-size:56px;font-weight:900;margin:0;line-height:1.2\">Found this useful?</h2><p style=\"font-size:32px;opacity:0.8;margin-top:24px;line-height:1.5\">Save this post for later 🔖<br>Follow for more tips</p><p style=\"font-size:24px;opacity:0.4;margin-top:40px\">@yourusername</p></div></div>"
}'
