Social images

Generate Open Graph (OG) images automatically for your website. When someone shares a link to your site on social media, a screenshot of that page is used as the preview image.

How it works

Verify your domain in the dashboard
Add the meta tag to your pages pointing to our service
We capture screenshots when social platforms request your OG image
Results are cached so subsequent requests are instant and free

<meta property="og:image" content="https://og.allscreenshots.com?url=https://yourdomain.com/page" />

No API key is needed in the URL. Your domain must be verified for images to be generated. Cache hits don't count toward your quota.

Setting up

1. Add your domain

Go to the Social images page in your dashboard and add your domain (e.g., example.com).

2. Verify ownership

Choose one of three verification methods:

Method	How it works
DNS TXT	Add a TXT record to your domain's DNS settings
Meta tag	Add a verification meta tag to your homepage
File	Upload a verification file to your web server

3. Add the OG meta tag

Add the following meta tag to each page where you want social images:

<head>
  <meta property="og:image" content="https://og.allscreenshots.com?url=https://yourdomain.com/page" />
  <meta property="og:image:width" content="1200" />
  <meta property="og:image:height" content="630" />
</head>

For dynamic pages, generate the URL programmatically:

// Next.js example
export const metadata = {
  openGraph: {
    images: [`https://og.allscreenshots.com?url=${encodeURIComponent('https://yourdomain.com' + pathname)}`],
  },
}

Configuration

Configure default capture settings for your domain in the dashboard. These settings apply to all social images generated for that domain.

Image dimensions

Setting	Default	Description
Width	1200	Image width in pixels
Height	630	Image height in pixels

Standard OG image size is 1200×630. Twitter recommends 1200×600.

Cache duration

Control how long images are cached before regeneration. Longer cache times mean fewer billable captures but slower updates when your pages change.

Duration	Use case
1-3 days	Frequently updated content
7 days	Standard websites (default)
14-30 days	Static content, rarely changes

Subdomains

Enable subdomain support to generate images for all subdomains (e.g., blog.example.com, docs.example.com) without verifying each one separately.

Appearance options

Setting	Description
Dark mode	Capture pages in dark mode (if your site supports it)
Block ads	Hide advertisements in captured images
Block cookie banners	Hide cookie consent popups

Output options

Setting	Options	Description
Format	PNG, JPEG, WebP	Image format (PNG recommended for quality)
Quality	50-100%	Compression quality for JPEG/WebP
Scale	1x, 2x, 3x	Device scale factor for sharper images

Timing options

Setting	Default	Description
Wait until	Network idle	When to consider the page ready
Delay	0ms	Additional wait time after page load
Timeout	30000ms	Maximum time to wait for page load

Customization

Setting	Description
Hide elements	CSS selectors for elements to hide (e.g., `.popup, #banner`)
Custom CSS	Inject CSS before capturing (e.g., fix sticky headers)

URL parameter

Pass the page URL to capture:

https://og.allscreenshots.com?url=https://yourdomain.com/page

Parameter	Type	Description
`url`	string	Required. The page URL to capture

Capture settings such as dimensions, dark mode, delay, and hidden selectors are configured per verified domain in the dashboard.

Caching

Social images are automatically cached to improve performance and reduce costs.

How caching works

First request for a URL generates a new screenshot (billable)
Subsequent requests serve the cached image (free)
After the cache TTL expires, the next request regenerates the image

Cache management

Clear cache: Clear all cached images for a domain from the dashboard

Clearing the cache will cause all subsequent requests to generate new screenshots until the cache is rebuilt.

Usage and billing

What counts toward quota

Action	Billable
First capture of a URL	Yes
Cache hit (serving cached image)	No
Refresh after cache expiry	Yes
Manual cache clear + recapture	Yes

Monitoring usage

View your social image usage in the dashboard:

Images generated: Billable captures this month
Cache hits: Free cached responses
Cache hit rate: Percentage of requests served from cache

Best practices

Different platforms have different requirements:

Platform	Recommended size	Notes
Facebook	1200×630	Standard OG size
Twitter	1200×600	Slightly shorter
LinkedIn	1200×627	Similar to Facebook
Discord	1200×630	Uses OG tags

Design pages for screenshots

For best results:

Above the fold: Key content should be visible without scrolling
Clean layout: Remove distracting elements with hide selectors
Readable text: Ensure text is large enough to read in thumbnails
Branding: Include your logo in a consistent position

Handle dynamic content

For pages with user-specific or frequently changing content:

<!-- Use a static preview URL for dynamic pages -->
<meta property="og:image" content="https://og.allscreenshots.com?url=https://yourdomain.com/preview/article-123" />

Create dedicated preview routes that show a clean, static version of the content.

Troubleshooting

Image not updating

The image may be cached. Either:

Wait for the cache TTL to expire
Clear the domain cache from the dashboard
