OG image inspector

Social platforms want a 1200×630 image under ~1 MB. Paste a page URL (or a direct image URL) — we fetch the og:image and check its real dimensions, weight and aspect ratio.

What this tool checks

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 looks at

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.

Frequently asked questions

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.
