If those tags are missing, platforms fall back to the and the first usable image they can find — often with poor results. Every platform reads the same core tags — og:title, og:description, og:image, and og:url — but each renders them differently: Slack and Discord show a full card with description, iMessage shows title and domain over the image, and WhatsApp usually crops the image to a small square thumbnail. Check the platform-specific pages below when a preview looks right in one app and wrong in another. ## Common use cases How teams put the Link Preview Checker to work. ### Content QA Verify previews look good before sharing in Slack, iMessage, or WhatsApp. ### Editorial workflows Confirm article metadata is correct before publishing or syndicating. ### Outreach Make sure cold emails and DMs render an attractive card every time. ## Frequently asked questions ### What is a link preview? ### Why is my link preview not showing? ### What image size do link previews use? ### How do I fix a wrong link preview? ### Do single-page apps work? ## Go deeper - Open Graph debugger — inspect the raw tags: https://uselinkpilot.com/tools/open-graph-preview - Redirect checker — follow the link's hops: https://uselinkpilot.com/tools/redirect-checker - Branded short links: https://uselinkpilot.com/branded-short-links ## Related tools More free utilities from LinkPilot.
