How to use this tool
- Paste the page's HTML source.
- Review the preview card and the list of any missing tags below it.
- Add the missing og: tags to your page and re-check.
Why preview Open Graph tags in the browser?
This reads your pasted HTML locally and only makes one optional network request — loading the og:image itself, directly in your browser, exactly like a social platform's crawler would when generating a preview.
Frequently asked questions
- Why doesn't the preview image load?
- The preview loads the og:image URL directly from your browser — if the image is on a private/staging server not reachable from where you're viewing this, or the URL is wrong, it won't render, but the checklist below still tells you whether the tag itself is present.
- Is this exactly what Facebook/LinkedIn will show?
- It's a close approximation of the common share-card layout — each platform renders slightly differently and may cache an older version of your tags, which is why they each provide their own official debugging tools (Facebook Sharing Debugger, LinkedIn Post Inspector) for a definitive check.
- What if I don't have og:description but do have a meta description?
- Most platforms fall back to the regular meta description when og:description is missing — this preview does the same, so you can see what actually gets used.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online OG preview tools |
|---|---|---|
| Works on staging/private pages | Yes — paste-based | Usually no |
| HTML ever leaves your device | No — 100% client-side | Often yes |
