Link preview mockup

Type a title, a description, the site name, and the page URL, then drop an image or choose a file. The cards for X, Facebook, LinkedIn, Slack, Discord, and iMessage update as you type, and a note appears when the title or description is longer than that app usually shows. The cards are approximations, not exact copies of each app. This runs in your browser. The image is not uploaded and it is not stored.

Site name

Slack and Discord put this above the title. The others use the domain from the URL.

Typical character limits in a wide window: X, title 70, and the large card leaves the description off. Facebook, title 80 and description 110. LinkedIn, title 100 and description 120. Slack, title 100 and description 140. Discord, title 70 and description 350. iMessage, title 60 and description 100. Apps also cut by line, so a narrow window cuts sooner. The same guidance is in the title and description guide. To write the tags, use the tag generator.
