OG preview from a URL
Paste any page URL — Slack, X, Discord, Facebook, LinkedIn, and iMessage all read these tags to render the link preview. swiftimg fetches the page once and renders the unfurl exactly like a real social client would.
What you're looking at
The card above is the unfurl that Slack, X, and most other social platforms render. The table lists every tag that was extracted — useful for debugging missing or stale metadata, and for spotting Twitter-specific overrides like twitter:image that differ from the OpenGraph default.
Keep working with your image
Open a local image in the editor for cropping and finishing touches. If you converted or resized it here, download the result first. When it is ready, upload it to get a share link or an embed snippet.
Local editing is free. Free uploads are public. Paid plans add private sharing.
Need a fast OG image too?
Every swiftimg viewer page emits a 1200x630 OG image and Twitter Card automatically — just paste the link.
