For a standard social preview, start with a 1200 × 630 pixel canvas, export the image to a stable public URL, and add that URL to the page’s og:image metadata. Use a browser editor for a few manually designed cards; choose a dynamic generator or code-based route when each page needs its own image.
What an Open Graph image generator does
The Open Graph protocol lets a web page become a rich object in a social graph, including a preview image when a link is shared. An image generator helps you design that visual and, depending on the tool, export an image, produce metadata, or render a different image for each URL.
The image itself is not the metadata: your page must identify the image with an absolute, publicly reachable URL in its HTML head. A polished graphic cannot appear in a preview if the sharing platform cannot retrieve that URL or find the metadata.
Choose the right way to generate your image
For occasional pages: use a browser editor
A browser-based editor is the simplest route for a landing page, article, or small site where images do not change often. The documented og-image.org workflow runs in the browser without a sign-up, server, or cost: choose a template, edit title, description, colors, and background, then download a PNG or copy the provided meta tags. Its templates are optimized for 1200 × 630 pixels. See the og-image.org documentation.
For repeatable designs: use a template service
A hosted template service can make a consistent family of cards easier to maintain. OGForge advertises a free editor, reusable templates, saved image URLs, 1200 × 630 output, and a dynamic API for production. These are the service’s advertised capabilities; compare its current terms and behavior for your use case at OGForge.
ogdynamic describes a free-form canvas whose layers can be marked dynamic and replaced using URL parameters or POST JSON. It also advertises permanent immutable image URLs and formats for Open Graph, X/Twitter, square, story, Pinterest, and custom sizes. See ogdynamic for its current feature details.
For sites with many changing pages: render images from code
If every product, article, or user-generated page needs a card, generating the image from page data avoids hand-editing each one. Vercel’s @vercel/og uses Satori and Resvg to convert HTML/CSS into PNG. Its documented ImageResponse defaults to 1200 × 630, supports custom fonts and common flexbox layouts, and adds cache headers. This approach provides programmatic control but requires a route, deployment, and compatible layout code.
Vercel documents support for flexbox and a subset of CSS, but not advanced grid layouts; supported font formats include TTF, OTF, and WOFF. Its documentation lists a 500KB bundle limit. Check the current Vercel OG Image Generation documentation before building around those constraints.

Use 1200 × 630 pixels as the standard starting canvas. It is the documented default in og-image.org and Vercel’s examples; a platform-specific format may call for a different size. Keep the essential text and logo away from the edges, because previews can be displayed at different sizes or cropped by a destination.
- Use a clear page title or short message as the visual focus.
- Keep contrast strong enough for a thumbnail and avoid relying on tiny body copy.
- Use a consistent typeface, colors, and logo placement across related pages.
- Use a descriptive alternative text value in metadata where it helps identify the image’s content.
- Export a format supported by your chosen workflow; the browser workflow described by og-image.org downloads PNG, while Vercel’s documented response is PNG.
Generate and publish a static image
- Choose a tool. Open a browser editor such as og-image.org and choose a template, or use a design application that can export the desired dimensions.
- Set the canvas. Use 1200 × 630 pixels unless you have a specific channel requirement for another aspect ratio.
- Customize the card. Add the page’s title and relevant brand elements. Check legibility at a small preview size.
- Export the image. Download the PNG and give it a stable filename, such as
article-title-og.png. - Host it publicly. Upload it to a location that sharing crawlers can fetch without logging in. Use an absolute HTTPS URL that will not change when the page is updated.
- Add the metadata. Place the tags in the page’s
<head>, replacing the example URL and descriptive text with your own values. - Deploy and validate. Inspect the rendered preview using the target platform’s available preview or sharing tools. Confirm the image URL is reachable and that the deployed page contains the new tags.
Add Open Graph and X/Twitter metadata
The Open Graph protocol defines og:image and supporting properties including secure URL, MIME type, dimensions, and alternative text. Add only values that accurately describe the actual image:
<meta property="og:image" content="https://example.com/images/article-title-og.png">
<meta property="og:image:secure_url" content="https://example.com/images/article-title-og.png">
<meta property="og:image:type" content="image/png">
<meta property="og:image:width" content="1200">
<meta property="og:image:height" content="630">
<meta property="og:image:alt" content="A concise description of the image">The og:image value should be an absolute URL, not a relative path such as /images/card.png. Set the type to the exported file’s actual MIME type and the dimensions to its actual pixel size. The secure URL is useful when the image is also available over HTTPS.
For an X/Twitter large-image preview, Vercel’s documentation shows summary_large_image as the card value. Add the corresponding tags with values matching the page and image:
Recommended Free Tools
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:image" content="https://example.com/images/article-title-og.png">Open Graph tags are documented by the Open Graph protocol. The correct preview can depend on how and when a destination fetches the page, so validate after deployment rather than assuming a local HTML change has taken effect everywhere.
Generate a unique image for each page
Use an API or dynamic template
For many pages with a shared design, a dynamic service can accept page-specific data and place it into named template layers. ogdynamic describes URL-parameter and POST-JSON approaches. This can suit systems that already have page data available, but design the integration around stable inputs and a stable image URL so a page’s metadata does not point to a different image on every request.
Use a framework rendering route
A code-driven route can render a card from the same title, author, description, or product data used by the page. Vercel’s @vercel/og is one documented option. The following example illustrates the documented ImageResponse pattern in a Vercel app route; adapt the data lookup and markup to your application:
import { ImageResponse } from '@vercel/og';
export const runtime = 'edge';
export async function GET() {
return new ImageResponse(
(
<div
style={{
width: '100%',
height: '100%',
display: 'flex',
flexDirection: 'column',
justifyContent: 'center',
padding: '64px',
background: '#101827',
color: '#ffffff',
fontSize: 64,
}}
>
<div style={{ fontSize: 28, color: '#8eb5ff' }}>Example site</div>
<div>A page-specific title</div>
</div>
),
{ width: 1200, height: 630 },
);
}That example uses a fixed title to show the response shape; a production route should obtain the title and other values from a validated page identifier or data source. Avoid accepting arbitrary untrusted markup as image content. Keep the route accessible to the crawler that fetches the page preview. Vercel recommends allowing OG routes in robots.txt.

ScreenshotNeo is a website screenshot API and MCP server from Yorker Media. It captures a rendered webpage; it is not an Open Graph image designer or a substitute for adding og:image metadata. It can help when you need a clean screenshot of a live page as an image asset. One GET request returns PNG, JPEG, WebP, or a PDF. Its consent, popup, and chat-removal steps can be turned off individually.
Here is the cURL call using the documented API pattern; replace the target URL and API key with your own. See the ScreenshotNeo API documentation for parameters and response details.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com -o shot.webpCookie banners, newsletter popups, and chat widgets are removed before the shot. Bot checks, blank pages, and failed loads are never billed; response headers identify the page verdict and billing status. An MCP server provides take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients. The Free plan includes 1,000 shots per month with no card; paid plans start at $5 for 3,000 shots. Every feature is on every plan. Learn more at ScreenshotNeo.

Troubleshoot a missing or incorrect preview
- The image does not appear. Open the exact absolute image URL in a browser without signing in. If it cannot be fetched publicly, the sharing crawler may not be able to fetch it either.
- The old card still appears. Check that the deployed HTML has the updated tags and that the image URL itself is stable and correct. A destination may retain a previously fetched preview; use its available preview validation or refresh mechanism.
- The wrong image or page title appears. Inspect the page’s deployed head for duplicate or conflicting metadata and confirm the URL is the one being shared.
- The image is cropped or hard to read. Keep important text and logos away from the edges and inspect the rendered card at a small size. Rework the layout rather than shrinking every element until it fits.
- The generated route fails. Check the deployed route, its required runtime and dependencies, and the CSS features used. Vercel’s documented renderer supports a subset of CSS rather than advanced grid layouts, and lists a 500KB bundle limit.
- A crawler cannot reach a generated image route. Verify that the route is publicly accessible and that crawler rules do not block it; Vercel specifically recommends allowing OG routes in
robots.txt.
Performance, reliability, and cost choices
A manually exported image has no per-page rendering step at request time, so it is straightforward to host and validate, but updating many cards is labor-intensive. A dynamic API or framework route reduces repetitive design work, but introduces a dependency on a rendering service or deployed code path. Confirm that the image can be fetched at the stable URL placed in metadata and validate real previews after deployment.
Best Value
For a small number of pages, a browser editor documented as free and requiring no sign-up can be enough. For page-specific images, assess the service’s current pricing and URL permanence directly; the supplied feature descriptions do not establish comparable pricing across OGForge, ogdynamic, and Vercel. No independent cross-provider benchmark establishes a universal winner for speed or social engagement.
Frequently Asked Questions
Does generating an image automatically add it to my website?
No. You still need to host the image and add its URL to the page’s Open Graph metadata.
Can I use a screenshot as an Open Graph image?
Yes, if the screenshot is the intended image and is hosted at a publicly fetchable URL. A screenshot API captures a page; it does not by itself create or publish the page’s `og:image` metadata.
