These are close approximations. Each app changes its design from time to time and may crop images differently.

Apps remember old previews. After fixing your page, ask them to read it again:
Why link previews matter
When you share a link, apps read a few hidden “Open Graph” tags on the page to build the preview card: a title, a short description and an image. A good card with a clear image gets far more clicks than a bare link, which matters for WhatsApp broadcasts, social posts and paid ads that point to your site.
- Image size: 1200 × 630 pixels works everywhere. Keep important text away from the edges, because some apps crop to a square.
- File size: keep the image under 300 KB. WhatsApp often skips large images and shows a plain link.
- Title: under 60 characters so it isn’t cut off.
- Description: one sentence, under 155 characters.
Questions
Why does my preview show an old image?
WhatsApp, Facebook and LinkedIn remember previews for days. Use the Facebook Sharing Debugger and LinkedIn Post Inspector buttons above to make them read the page again. For WhatsApp, adding something like ?v=2 to the end of the link makes it fetch a fresh preview.
Why does WhatsApp show no image?
The most common reasons are an image over 300 KB, an image address starting with http:// instead of https://, or a missing og:image tag. The checklist above tells you which one it is.
Does this work for pages behind a login?
No. Apps can only read public pages, and so can this tool. If a page needs a login, its preview will be empty everywhere.
Do you store the links I check?
No. We read the page once to build the preview and keep nothing.
