# iMessage link preview checker

> iMessage fetches the page from the sender’s device and shows only the title, domain and image or icon.

Check a URL: https://sharelint.pages.dev/?url=<your-url>, or as Markdown: https://sharelint.pages.dev/api/preview?format=md&url=<your-url>

## Tags iMessage reads (fallback order)

- Title: `og:title` -> `<title>`
- Image: `og:image` -> `apple-touch-icon`

## Image requirements

- Recommended: 1200×630
- Minimum: 150×150
- Maximum weight: Keep under 1 MB
- Formats: JPEG, PNG

## Card layout

With an image, it shows a large image above a grey bar with the title and domain. Without one, it shows the apple-touch-icon beside the title.

## Refreshing the cache

Previews are cached on the device. Change the URL to see an update.

## Common problems

- A generic globe icon: add og:image, or an apple-touch-icon at 180×180.

Rule confidence: observed.
