## What it does

An og:image checker fetches the image declared in a page's og:image meta tag and reports its real pixel dimensions, file weight, and aspect ratio, comparing them against the 1200×630 / 1.91:1 standard. The og:image is the thumbnail that renders when your URL is shared or cited on social platforms, in chat apps, and increasingly in AI answer surfaces — a wrong size, oversized file, or off-ratio image gets cropped, blurred, or dropped entirely.

## What it checks

- **Aspect ratio (1.91:1)** — The width-to-height proportion of the image; platforms crop anything that deviates, so 1.91:1 (1200×630) fills a large preview card edge-to-edge without letterboxing.
- **Dimensions (1200×630)** — The image's pixel width and height; below roughly 600×315 a platform may fall back to a small square thumbnail or none, so 600×315 is the minimum for a large card and 1200×630 is the recommended size.
- **File weight** — The image's byte size; Facebook caps og:image around 8 MB and slow-loading images can be skipped by scrapers, so keeping it well under 1 MB is ideal.
- **Tag presence & absolute URL** — Whether og:image exists and points to a fetchable absolute address; a missing tag or relative path forces the platform to grab a random on-page image or show nothing.
- **Image format** — The file type (JPG/PNG/WebP); a static, widely supported raster format renders everywhere, whereas some platforms ignore SVG or animated formats.

## How to use it

1. Paste your page URL into the checker and run it.
2. Review the reported dimensions, weight and ratio against the 1200×630 / 1.91:1 target, and note any red flags — wrong ratio, oversized file, or a missing tag.
3. Fix the source image (re-export to 1200×630, compress under ~1 MB) or the og:image tag, redeploy, and re-check.

## FAQ

### What is the ideal og:image size?

1200×630 pixels at a 1.91:1 aspect ratio is the recommended size — it fills a large link preview on Facebook, LinkedIn, X and most chat apps without cropping. The practical minimum for a large card is 600×315.

### How big can the og:image file be?

Keep it under 8 MB, which is Facebook's hard cap, and ideally under 1 MB. Heavy images load slowly and some scrapers time out and skip them.

### Why isn't my image showing when I share the link?

Common causes are a missing or relative og:image URL, an image below 200×200 px, a file over the platform's size limit, or a stale cache. Confirm the tag resolves to an absolute URL and re-scrape the link with the platform's sharing debugger.

### What aspect ratio should og:image use?

1.91:1 (landscape) is the standard for large summary cards, while square 1:1 suits smaller thumbnails. Off-ratio images get center-cropped and can lose text or the main subject.
