CMS & Blog Covers
Auto-generate cover images and social sharing cards when publishing. OG images are just one example.
The Problem
Without RendShot
Every article needs a manually designed cover image
Missing OG images mean ugly link previews on social media
Design bottleneck slows down publishing cadence
Hook into your CMS publish event. RendShot generates a cover image from your article title, author, and category — automatically.
Unlike next/og (Next.js only, limited styling) or manual Figma exports (slow), RendShot works with any CMS or framework via REST API with full CSS support.
How It Works
Three steps. Under a minute.
Design your template
Write HTML + CSS for your image layout. Use Tailwind, Google Fonts, any CSS feature.
Call the API
Send a POST request with your template and dynamic data. Get back a CDN-hosted image URL.
Automate at scale
Hook into your workflow — n8n, Windmill, CMS webhooks, or your own backend. Images on demand.
Integration
One API call. That's it.
curl -X POST https://api.rendshot.ai/v1/image \
-H "Authorization: Bearer rs_live_..." \
-d '{ "template_id": "blog-cover",
"variables": { "title": "Zero-Downtime Deployments", "author": "Mike" },
"width": 1200, "height": 630 }'FAQ
Common questions
Can I integrate RendShot with my CMS?
Yes. Any CMS with webhooks or an API (WordPress, Strapi, Sanity, Contentful) can trigger RendShot on publish. Use the REST API or JavaScript/Python SDK.
What sizes should I generate for social sharing?
Twitter/LinkedIn: 1200×630 (1.91:1). Facebook: 1200×630. Xiaohongshu: 1080×1440 (3:4). Generate multiple sizes from one template by changing width/height parameters.
