Documentation / Sharing & link previews

Sharing & link previews

When you paste your DaLinkz link into Discord, X, WhatsApp, iMessage and similar apps, they show a little card with a title, a line of text and an image. You choose what goes on that card under Sharing in the portal. It's free on every page.

The three fields

The Live preview beside the form shows roughly how your card will look. Every app frames it a little differently, so treat it as a guide.

Choosing an image

• Size: about 1200×630px, a wide 1.91:1 rectangle. Keep important text and faces away from the edges, because some apps crop.
• Direct link: like every image on DaLinkz, this must be a link to the image file itself. Some screenshot and image sites send apps a web page instead of the picture, which leaves the preview blank. Use the host's direct link, which often starts with i.. See direct links vs share links.
• Stay readable small: previews are often shown as thumbnails. Bold, simple images work best.
• Rights: only use images you're allowed to use.

Why an old preview still shows

Chat and social apps save a copy of each link's preview the first time they see it, and keep reusing it for a while. So after you change your title, description or image:

• Messages you posted before keep the old preview. That's normal.
• New posts usually pick up the change, but some apps take a while.
• To force a fresh preview straight away, post the link with something unique on the end, such as dalinkz.com/yourlink?v=2. It still opens your page, but the app treats it as a new link. Change the number each time you test.
