Social Media Image Automation at Scale

Create templates for Instagram, Twitter, LinkedIn, and Facebook. RenderStack generates on-brand social images from your data — thousands per day, zero manual design.

Why Social Media Image Creation Doesn't Scale

Marketing teams publish dozens of social posts daily across multiple platforms. Each platform requires different dimensions (1080x1080 for Instagram, 1200x628 for Facebook, 1600x900 for Twitter). Creating each variation manually means designers spend more time resizing than creating. Content calendars slip, campaigns launch late, and brand consistency suffers when different team members create images with slightly different fonts, colors, and layouts.

Before RenderStack

Designers manually resize for each platform
Brand consistency drifts across campaigns
Content calendars slip due to design bottlenecks
No way to personalize images at scale
A/B testing requires manual variant creation

With RenderStack

One template set covers all platforms
Pixel-perfect brand consistency always
Images generated instantly from data
Personalized images for every audience segment
Unlimited A/B test variants via API

How It Works

Create Platform Templates

Design templates for each social platform size — Instagram square, Facebook landscape, Twitter card, LinkedIn post, and story formats.

Define Dynamic Content

Mark headlines, images, CTAs, dates, and branding elements as dynamic layers. Set up fallback chains for optional content.

Automate Generation

Connect to your content pipeline. For each post, call the API with your content data and get back ready-to-publish images for every platform.

Key Features for Social Media Automation

Multi-Format Templates

Design once, adapt for Instagram, Facebook, Twitter, LinkedIn, and story formats. Each template uses the same dynamic layers with different layouts.

Conditional Visibility

Show or hide elements based on post type — promotional badge for sales, event date for announcements, product image for launches.

Brand Asset Management

Upload logos, fonts, and brand colors once. Every generated image uses your exact brand assets automatically.

Batch Generation

Generate an entire week's content calendar in one workflow. Process hundreds of posts across all platforms in minutes.

Generate an Instagram Post

bash

curl -X POST https://api.renderstack.io/v1/render/instagram-post \
  -H "Authorization: Bearer rs_master_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "overrides": {
      "headline": { "text": "New Feature Launch" },
      "body": { "text": "Announcing Smart Cover — AI-powered image cropping" },
      "heroImage": { "src": "https://cdn.example.com/campaign/hero.jpg" },
      "ctaText": { "text": "Learn More" }
    }
  }'
