Create the artwork in Canva, export it, then add its publicly reachable image URL to the webpage’s og:image metadata. Exporting the image alone does not attach it to a page or make it appear in a link preview. For a LinkedIn-friendly landscape image, use 1200 × 627 pixels, design for a small preview, and check that LinkedIn can fetch the exported file.
What an Open Graph image is—and what Canva does
An Open Graph image is the image a webpage identifies for use when that page is shared as a link. The page points to the image through an og:image meta property in its document head. Canva helps you create and export the image; it does not, by itself, set the metadata on your website.
That distinction explains a common failure: a polished image can exist in your Canva account or on your computer, yet sharing the page still shows no image or an old one. The page must reference the exported file at a usable URL, and the sharing service must be able to retrieve it.

The Open Graph protocol specifies four basic required properties for a page: og:title, og:type, og:image, and og:url. When you specify an image, the protocol says to provide og:image:alt as well. It also defines optional image metadata such as og:image:width and og:image:height. Treat the image as one part of the page’s sharing metadata, not as a standalone Canva setting.
Choose the dimensions for the place the page will be shared
For LinkedIn, start at 1200 × 627 pixels
LinkedIn Help lists 1200 × 627 pixels as the minimum dimensions for a share image, recommends a 1.91:1 ratio, and sets a 5 MB maximum. These are LinkedIn specifications, not a universal guarantee for every social network or every way of publishing a link. LinkedIn’s help article was marked as last updated two years before September 29, 2026, so check the current rules if a particular campaign depends on an exact limit.
A 1200 × 627 pixel canvas has the recommended approximate landscape proportion. If LinkedIn is the main destination, use that as your starting canvas rather than designing square artwork and relying on a crop. If the page will be shared on several networks, decide whether one landscape composition is acceptable everywhere or whether each destination warrants its own version.
For several networks, confirm each destination’s current requirements
Image dimensions, aspect ratios, accepted file types, file-size ceilings, and preview behavior can differ by platform and may change. Canva’s sharing guidance also notes that third-party platforms manage their own publishing rules. Its listed direct-sharing limits are not a substitute for checking the requirements of your specific website-link workflow: for example, Canva lists 4 MB for PNG/JPG Facebook uploads, 10 MB for JPG LinkedIn uploads through Canva, and 3 MB for Twitter images. Those are Canva-mediated upload figures, not universal Open Graph limits.
Rank #2
If you need a single image for multiple destinations, prioritize a composition that remains legible when reduced or cropped. For a campaign with important text, logos, or product details near the edges, separate versions can be safer than assuming every preview displays the full canvas. Canva’s general download guidance says images below 500 × 500 pixels are likely to look blurry; that is not an Open Graph size recommendation.
Create the image in Canva
- Choose the destination. Decide whether the image is primarily for LinkedIn or for another network. For LinkedIn, set the design to 1200 × 627 pixels. Canva’s general size guide can help you explore social formats, but its reviewed guidance does not establish the current exact sequence of custom-size controls in the editor. Use the size controls shown in your current Canva workspace rather than relying on an assumed menu label.
- Build a clear composition. Give the image one focal point and a strong contrast between its main elements. If you include text, keep it short enough to read when the image is displayed as a small preview. Avoid putting essential wording, a logo, or an important subject close to the outer edges: previews may be reduced or cropped differently from the full-size design.
- Review it at a small size. Zoom out or view a reduced copy of the design. Check whether the main subject and any essential wording remain understandable without opening the image at full size. This is a practical design check, not a platform guarantee about how every preview will render.
- Export a suitable file. Canva recommends PNG for social-media graphics with text. JPG can be useful when a smaller web image file matters. Compare legibility against file size, and follow the receiving platform’s accepted formats and size ceiling. Canva notes that social platforms may compress uploaded images, so inspect the exported file rather than assuming it will look exactly as it does in the editor.
- Save the exported file somewhere your site can serve it. The metadata needs an image URL, not merely a Canva design link or a file that exists only on your device. Use the final exported asset at the location your website makes available for sharing, and retain the exact URL that the page will reference.
Add the image URL to the webpage’s metadata
Once the image is exported and hosted, update the page’s <head> metadata. Put the image’s actual usable URL in og:image. Set og:title to the page title you want associated with the share, og:type to the appropriate page type, and og:url to the page’s own URL. Include og:image:alt describing the image for people who cannot see it. The optional width and height properties can describe the exported image’s dimensions.
- Use the image’s actual public URL. The value should resolve to the exported asset, not to a local file path or a private Canva workspace view.
- Keep page and image roles separate.
og:urlidentifies the webpage being shared;og:imageidentifies the artwork used for that page’s preview. They are not interchangeable. - Keep metadata consistent with the page. The title and URL should describe the page being shared, and the image description should describe the artwork rather than repeat unrelated page text.
- Use the correct version of the file. If you replace the exported artwork, make sure the metadata points to the intended file and then inspect what the sharing service retrieves.
How you edit the head depends on the site platform or framework. Use its page-level social-sharing or Open Graph fields if it provides them; otherwise update the page template or source that emits the head. Do not paste the tags into the visible body and assume they will be interpreted as page metadata.

Check the image as a sharing service would
After the metadata is published, inspect the page preview using the intended sharing service’s available preview or inspection workflow. Verify both the selected image and the title and page URL. A correctly sized image can still fail if the platform cannot fetch it. LinkedIn specifically notes that retrieval can be blocked when the page or image location is protected or otherwise inaccessible.

- Open the final image URL in a way that does not depend on your logged-in Canva session, and confirm it returns the exported image.
- Check that the website is not restricting the image location from the sharing service.
- Confirm the file is within the destination’s current size and format requirements.
- Check the page’s published metadata, not just the settings screen where you entered it.
- If a preview still shows an older image, verify the current metadata and file URL before changing the design again; the issue may be retrieval or a stored preview rather than the Canva artwork.
PNG or JPG: choose based on the artwork and limits
| Format | Useful when | Trade-off to check |
|---|---|---|
| PNG | The graphic includes text or other elements where clear edges matter. Canva recommends PNG for social-media graphics with text. | Check the exported file size against the destination’s limit. |
| JPG | A smaller web image file is a priority, especially for photographic artwork. | Inspect fine text and edges after export, and confirm the destination accepts the file. |
Neither format guarantees a particular preview result. The receiving platform’s current format rules and size limits still apply, and Canva notes that social platforms may compress images.
Troubleshooting common Open Graph image problems
The preview has no image
First check that the published page has an og:image property and that its value is the URL of the exported image. Then check whether that URL is fetchable without access to a private account or protected directory. LinkedIn identifies blocked or protected image locations as a reason image retrieval can fail.
The wrong or an old image appears
Inspect the metadata the live page emits and confirm og:image points to the intended current asset. If the page points to an older URL, fix the page metadata. If it points to the correct one, inspect the target service’s preview or inspection workflow rather than repeatedly exporting the same Canva design.
The image looks blurry
Check the exported dimensions and review the composition at the size it is likely to appear in a preview. Canva’s general guidance warns that images below 500 × 500 pixels are likely to look blurry when downloaded, but that threshold is not a recommended share-image size. For LinkedIn, its stated minimum is 1200 × 627 pixels.

Check the destination’s current file-size and format limits, then verify that the image URL resolves to the exported file and is not access-restricted. A Canva direct-sharing upload limit should not be assumed to govern a separately hosted website preview image.
The design is cropped unexpectedly
Revisit the destination and the composition. Keep essential text and imagery away from the edges, and preview the image at reduced size. If two networks display the same artwork differently, consider exporting destination-specific versions instead of forcing one crop to suit every preview.

After you publish the page and its Open Graph metadata, you can use ScreenshotNeo to capture the rendered page for a visual check. It is a screenshot API, not a Canva design editor and not a replacement for adding the page’s og:image metadata. One GET request returns a PNG, JPEG, WebP, or PDF capture. The example below captures a page; replace the target URL with the page you want to inspect. See the ScreenshotNeo API documentation.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpScreenshotNeo removes cookie/consent banners, newsletter popups, and chat widgets before capture, and each step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing; response headers identify the page verdict and whether the request was billed. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for AI agents, including Claude, Cursor, and other MCP clients. The Free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000 screenshots.

Final publishing checklist
- The canvas matches the sharing destination; for LinkedIn, the image is at least 1200 × 627 pixels, with a 1.91:1 ratio recommended and a 5 MB maximum listed by LinkedIn Help.
- The exported file is suitable for the artwork and within the destination’s current limits.
- The published page’s
og:imagepoints to the exported file, and the other required basic Open Graph properties describe the page. - The image URL is fetchable by the sharing service, and the preview has been inspected after publishing.
Frequently Asked Questions
Can the same Canva image be used for more than one webpage?
Yes. An image can be referenced by more than one page, but each page still needs its own appropriate Open Graph metadata, including its own page URL and intended title.
Does the Open Graph image replace the page’s visible thumbnail or hero image?
No. It identifies artwork for link-sharing previews; it does not, by itself, change the page’s visible content or its other image fields.
