Discord embed preview for any link

Paste a URL to see the embed Discord draws from your tags — site name, title, description, image and the colour bar from theme-color — with the image checked against Discord's documented formats (PNG, GIF, JPG, WebP, AVIF).

No signup, no Discord login. We fetch the page the way a crawler does (HTML only, no JavaScript) and do not store the URL.

Discord link preview not showing or not updating?

  1. Image too small? Add twitter:card = summary_large_image.
  2. Discord keeps a preview for a while (about 30 minutes). For a new one now, add a query string to the URL.
  3. Let Discordbot through robots.txt and bot protection.
  4. Use one of PNG, GIF, JPG, WebP, AVIF for the image; SVG is not among them.

A preview image for every page, on Discord and everywhere else

Most broken previews have no image at all. Shareglint renders one for every page from its title — one meta tag, no code — at a size that passes every documented limit (the sizes). 100 images a month free.

Questions

How do I get a big image in a Discord embed?

Add <meta name="twitter:card" content="summary_large_image"> next to og:image. Discord shows the image large under the text instead of as a thumbnail.

How do I change the colour of the Discord embed bar?

Set <meta name="theme-color" content="#ff7a18"> (any colour) in the page head.

Why does Discord show an old embed?

Discord caches embeds for a short time. Wait, or post the URL with a query string to get it fetched again.
