Fix what's flagged
Each problem links to a plain-English fix, with the exact tag to add. Re-run the check to confirm it is live.
Why Discord has no preview tool
Discord has no embed debugger for links. The only way to see an embed there is to post the link in a channel, and Discord keeps the embed it fetched for a while, so a fix may not show straight away.
This checker shows the embed without posting anything, lists each tag it read, and flags the ones that change how Discord lays it out.
The tags Discord reads
Discord reads both Open Graph and Twitter Card tags, plus the theme-color meta tag for the embed's side bar. In practice twitter:card decides whether the image is shown large under the text or as a small thumbnail beside it.
| Tag | Falls back to | Notes |
|---|---|---|
og:site_name | None | The small line above the title. |
og:title | <title> | The blue, linked headline. |
og:description | Meta description | Shown in full under the title. |
og:image | twitter:image | Shown large only with summary_large_image. |
twitter:card | None | Set summary_large_image for the full-width image. |
theme-color | None | Colours the bar down the left edge of the embed. |
<meta property="og:site_name" content="Your site" />
<meta property="og:title" content="Your page title" />
<meta property="og:description" content="One or two sentences." />
<meta property="og:image" content="https://example.com/og.png" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="theme-color" content="#5865f2" />Discord embed image size
Discord publishes no size spec, but it lays out the large image at the same 1.91:1 ratio as other platforms, so use 1200 × 630. Without twitter:card set to summary_large_image, the image shrinks to a thumbnail beside the text.
