A missing og:image
A page with no og:image tag gets flagged as one of three possible errors, since most platforms render a card with no image or skip the card entirely.
Open Graph checker (link preview)
Paste your page's HTML source (or type the fields by hand) and this tool checks your Open Graph title, description and image for the length and presence issues that make a shared link look broken — a missing image, a title likely to get truncated, or a description that's too short or too long. There is no backend here, so it cannot fetch a live URL for you.
Check your Open Graph tags
Nothing is uploaded — parsing happens entirely in your browser. This cannot fetch a live URL (no backend to do that from), which is why it works from pasted source instead.
Option B — enter the fields directly

How to check your link preview
- Copy your page's HTML source. Right-click the page and choose View Page Source, then copy all of it.
- Paste it into the checker. Paste the source into the HTML box and click the button to fill the fields automatically.
- Or enter the three fields by hand. Type the title, description and image URL directly if you already know them or prefer not to paste HTML.
- Review each flagged issue. A missing field is an error; a too-long or too-short field is a warning worth reviewing before you share.
- Check the preview card. The rendered mockup shows roughly how the link will look once shared, though every platform renders it slightly differently.
Worked examples
An 80-character title
Titles commonly get truncated around 60 characters, so an 80-character og:title is flagged as likely to be cut off with an ellipsis.
Open Graph checker FAQ
- Can this tool check my live URL directly?
- No — there is no backend here to make that request, so it works from HTML you paste in or fields you type by hand instead.
- Where do I find my page's HTML source?
- Right-click anywhere on the page in most browsers and choose View Page Source, then copy everything and paste it in.
- What happens if og:title is missing?
- Most platforms fall back to the page's plain title tag, which is often written for search, not for a shared link.
- Why does image size not get checked pixel by pixel?
- This tool checks the image URL's presence and whether it uses HTTPS; checking exact pixel dimensions would need to load the image, which the preview below also attempts.
- Does this tool store or send my pasted HTML anywhere?
- No — parsing happens entirely in your browser, and nothing you paste or type is uploaded or saved.
- What is the difference between this and the Open Graph preview tool?
- They share the same widget — this page emphasizes checking your tags for issues; the preview page emphasizes seeing the rendered card.
