When you paste a link into X, LinkedIn, Slack, or WhatsApp, the platform fetches the page and builds a preview card. Ordinary shorteners just pass through whatever the destination provides, which is often wrong, generic, or missing entirely.
Snipvio lets you override it per link.
Setting a card
Edit any link and fill in the Social card (Open Graph) fields:
- Title: the headline on the card, up to 120 characters
- Description: the supporting line, up to 300 characters
- Image URL: a full
httpsURL. 1200×630 pixels is the standard that looks right everywhere.
How it works
Snipvio identifies preview crawlers by their user agent. When one of them requests your link, it receives a small page carrying your Open Graph tags. Real visitors never see that page: they get the normal instant redirect.
This means the card you design is what gets shown, regardless of what the destination's own tags say.
When this is worth it
- Linking to an article whose stock image is poor
- Sharing a PDF or document that has no preview at all
- Running the same destination across several campaigns and wanting different framing for each
- Pointing at a site you do not control and cannot edit
Practical notes
Platforms cache preview cards aggressively. If you change a card after sharing, existing posts often keep the old preview. Set your card before the first share.
Your image must be publicly reachable. Files behind a login or on a private network will not render.
Frequently asked questions
What is a social card?
It is the preview that appears when a link is pasted into a social network or chat app: a title, a description and an image. By default the preview comes from the destination page. A custom social card lets you control it per link.
Which plans include custom social cards?
Custom social cards are a Premium feature.
What image size should I use?
1200 by 630 pixels, served over https. That is the size the major platforms expect and it renders correctly across all of them.
Why has my preview not updated?
Platforms cache previews aggressively, often for days. The card is correct for anyone seeing the link for the first time; existing posts may keep showing the old preview until that platform refreshes its cache.
