An Open Graph image is the visual preview attached to a shared page link. To create one, design a representative image, publish it at a stable public URL, and add that absolute URL to the page’s og:image metadata. A practical starting canvas is 1200×630 pixels (about 1.91:1), but the Open Graph protocol does not mandate one universal size, so check the requirements of the platforms your audience uses.
What an Open Graph image is
The Open Graph protocol lets a web page become a rich object in a social graph. Its core metadata is placed in the document’s <head> and identifies the page title, type, image and canonical URL:
og:title— the title shown with the shared link.og:type— the kind of object, commonlywebsitefor a normal page.og:image— the image URL used for the preview.og:url— the page’s canonical URL.
You can also provide og:description and structured image properties such as MIME type, width, height and alternative text. The image itself is not embedded in the HTML; crawlers fetch it from the URL you publish.
Choose a canvas and file format
Use 1200×630 as a practical baseline
A current implementation guide recommends 1200×630 pixels, approximately a 1.91:1 ratio, as a broad-compatibility starting point. This is a practical recommendation, not a universal protocol requirement. Services may crop or display the image differently, so keep important text and branding away from the edges and inspect the preview on the platforms that matter to your readers.

Pick a format that matches the artwork
- PNG: useful for crisp text, logos and illustrations.
- JPEG: often suitable for photographic backgrounds and smaller files.
- WebP: can be efficient where the receiving platform accepts it.
There is no single “best” format for every network. Confirm the accepted formats and size limits of the services where your links are shared. Next.js’s file convention currently documents JPG, JPEG, PNG and GIF for an opengraph-image file.
Decide between a static and generated image
| Approach | Good fit | Trade-off |
|---|---|---|
| Static image file | A small site or pages whose preview art changes rarely | Simple to create and publish; each page-specific change requires another file and metadata update. |
| Code-generated image | Many routes or content that changes by page | Repeatable and route-aware, but requires implementation and maintenance. |
| Visual editor such as Figma | Someone wants to compose or edit artwork visually | Useful for creating the image; the metadata still has to be added to the page. |
Figma’s documentation describes uploading and editing images in a design. It is an optional creation tool, not a requirement of Open Graph.
Create the artwork
- Choose the page’s primary idea and write a short, readable headline.
- Set the document to 1200×630 pixels unless a target platform calls for another size.
- Use strong contrast and a restrained type scale so the design remains legible in a small preview.
- Include only information that represents the page. Do not make the image promise content the page does not contain.
- Keep essential text, logos and faces inside a safe central area because platform crops vary.
- Export a web-ready file and give it a descriptive filename, such as
open-graph-images-guide.png.
For a handful of pages, a static design from a visual editor is usually the least complicated route. For a blog, catalog or documentation site with hundreds of URLs, generate the artwork from route data so a title, author or category can be changed without manually editing every file.
Publish the image at a stable absolute URL
Upload the file to a location that unauthenticated crawlers can reach over HTTPS. The value of og:image should be a complete URL, not a relative path such as /images/card.png. For example:
Free tools Windows power users keep installed
One-click scans. No signup required.

Add the Open Graph metadata
Put these tags in the page’s document head. The example uses the practical 1200×630 canvas; replace the URLs and text with values for your page.
<meta property="og:title" content="A page title" />
<meta property="og:type" content="website" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:image" content="https://example.com/images/page-preview.png" />
<meta property="og:image:alt" content="A concise description of the image contents" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:description" content="A short description of the page." />Write image alt text as a description
The protocol says that a page specifying og:image should also specify og:image:alt. Describe what the image contains—for example, “Blue map of coastal hiking routes with the title Weekend Trail Guide”—rather than writing a caption such as “Read our guide.” Keep the text concise and accurate.
Handle multiple images deliberately
You may provide more than one og:image. When values conflict, the first image in document order takes preference. Put the preferred image first, then place its structured properties immediately after it:
<meta property="og:image" content="https://example.com/images/preferred.png" />
<meta property="og:image:alt" content="The preferred preview artwork" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:image" content="https://example.com/images/alternate.png" />
<meta property="og:image:alt" content="An alternate preview artwork" />Keep each width, height, MIME type and alt declaration associated with the image root it describes.

Generate Open Graph images with Next.js
Static file convention
Next.js supports an opengraph-image file in a route segment. Add the file to the segment that owns the page—for example, an image file alongside a route’s page file. Next.js then adds the relevant metadata for that route. Its current guide documents JPG, JPEG, PNG and GIF files and demonstrates a 1200×630 image.
Programmatic route
When every article needs different text or artwork, use an opengraph-image route to generate the image from route data. Keep the generated response publicly fetchable and ensure the resulting metadata resolves to an absolute URL in production. The implementation details depend on your Next.js version and deployment adapter, so verify the current Next.js guide before choosing runtime-specific APIs.
Inspect and troubleshoot the result
The preview shows no image
- View the deployed HTML source and confirm that
og:imageis in the server-rendered<head>. - Check that the value is an absolute HTTPS URL and that opening it without a session returns the image.
- Confirm the response is an image with the expected MIME type, not a redirect to a login or error page.
- Check spelling: Open Graph properties use the
propertyattribute, notname.
The wrong image is selected
Look for multiple og:image tags. The first one has preference, so reorder the tags and keep the structured properties beside the intended image.
The artwork is cropped or text is missing
Platform display behavior is not identical. Rework the composition with wider safe margins, reduce text, and inspect the actual shared-link preview rather than relying only on the source file.

Changes do not appear immediately
Preview crawlers can cache fetched metadata and images. After deployment, confirm that your server serves the new file and then use the platform’s available URL-inspection or preview-refresh mechanism. Allow for a delay when a service has not fetched the page again.
The image works locally but not after deployment
Replace localhost and relative paths with production absolute URLs, deploy the image to the same environment as the page, and test it from a separate network or an unauthenticated request. A private firewall, expiring signed URL or robots configuration that blocks the crawler can prevent retrieval.
Validate before sharing
- Confirm
og:title,og:type,og:urlandog:imageare present once with the intended values. - Check that
og:image:altdescribes the visible content. - Open the image URL directly and verify its dimensions, format and HTTPS certificate.
- Inspect the final rendered head, including pages generated by a framework.
- Test a real shared-link preview on each important platform and note any cropping.
- Keep the image URL and design version documented so future edits do not break old pages.

Keep the metadata maintainable
Store the image path with the page record or route configuration rather than scattering it through templates. When changing artwork, preserve the old URL if existing shares still depend on it, or provide a redirect and verify that the receiving crawler follows it. For generated images, test long titles, non-Latin characters, missing author data and unusually long route names so one malformed record cannot produce a blank card.
Frequently Asked Questions
What is the recommended Open Graph image size?
Use 1200×630 pixels as a practical starting canvas, then verify the current requirements and cropping behavior of the platforms important to your audience. The Open Graph protocol itself does not prescribe one universal pixel size.

Choose based on the artwork and the destination platform: PNG is suitable for crisp text and logos, JPEG for photographs, and WebP where it is accepted. Confirm the platform’s current format and file-size rules.
Does every page need a different Open Graph image?
No. A shared image works for pages with a common identity. Use page-specific static files or a generated route when the preview needs to reflect each article, product or route.
