Frequently asked questions
Why does my link not generate a preview in Discord?
Discordbot requires a public URL that responds with 200 OK within 3 seconds, returns valid HTML, and is not blocked by Cloudflare bot protection or robots.txt.
How does Discordbot handle image dimensions?
Images with aspect ratio near 1.91:1 or 16:9 render as full-width banner embeds. Square or small images (< 400px wide) are rendered as compact thumbnails on the right.
Can I force Discord to clear its cached preview?
Discord caches embed previews aggressively. To clear the cache or test a new image, append a query parameter (e.g. `https://example.com/page?v=2`) to the URL when sharing.
What is the theme-color meta tag?
The `<meta name="theme-color" content="#hex">` tag specifies the color of the vertical strip along the left side of the Discord embed card.
