OG CHECKER

Check how your link looks on Discord

Discord automatically generates rich embeds when links are posted in channels and DMs. These embeds feature a colored sidebar, title, description, and image — making them one of the most visually rich link previews of any platform. Discord reads Open Graph tags and also supports some unique features like theme-color for the embed accent.

How Discord Renders Link Previews

When a link is posted in a Discord channel, Discord's crawler generates an embed card:

  1. og:title — the bold blue (or theme-colored) title link. Falls back to <title>.
  2. og:description — body text below the title. Discord supports more text here than most platforms — up to about 350 characters.
  3. og:image — displayed as a large image below the text, or as a small thumbnail if the image is square.
  4. og:site_name — shown as a small label above the title.
  5. theme-color — a <meta name="theme-color"> tag sets the colored left border of the embed. This is unique to Discord.

Discord caches embeds for approximately 15 minutes to 1 hour. There's no official cache-clearing tool, but you can append a query parameter to force a new scrape.

Discord Image Requirements

Landscape images render large below text. Square images render as small thumbnails on the right. Discord also supports animated GIFs in embeds.

Discord OG Tag Tips

  1. 1Set <meta name="theme-color" content="#6366F1"> to brand the left sidebar of your Discord embed. This is one of the most visually distinctive features of Discord embeds and most sites miss it.
  2. 2Discord is generous with description length — you can use up to 350 characters in og:description before truncation. Use this space to write a compelling summary.
  3. 3Use landscape images (1200x630) for large embed images, or square images for a smaller thumbnail on the right side. Discord auto-detects the layout based on aspect ratio.
  4. 4Discord supports og:video for video embeds. If you link to a page with video content, include this tag to get inline video playback directly in the chat.
  5. 5Set og:site_name — Discord shows it as a small gray label above the title. It provides context and brand recognition, especially when multiple links are shared in a channel.
  6. 6Discord's cache is relatively short-lived. If your embed looks wrong, wait 15-30 minutes or add ?v=timestamp to the URL to force a fresh fetch. There is no official debugger tool.
  7. 7Avoid relying on JavaScript-rendered OG tags. Discord's crawler does not execute JavaScript — it only reads the initial HTML response. If your meta tags are injected client-side (e.g., by a SPA framework), Discord will see an empty preview. Read our complete guide to Open Graph tags for best practices.
  8. 8For the colored embed border, Discord reads meta[name="theme-color"] before any OG tag. Match it to your brand color for a polished, recognizable embed in every server.
