Common Open Graph image specs

Keep your image under 8 MB. Use JPG (quality ~80) or PNG, and put the key content toward the center so it survives cropping.

Why 1200×630 matters

The Open Graph image is the picture shown when someone shares your page on Facebook, LinkedIn, X, or a messaging app. The widely recommended size is 1200×630 pixels, an aspect ratio of about 1.91:1. At this size the image is large enough to look crisp on high-resolution screens while still fitting the standard share-card layout. Smaller images may be scaled up and look blurry; images with a very different ratio get cropped, often cutting off your text or logo.

This checker reads the image you provide — either from a URL or from a local file on your device — and reports its width, height, ratio and file size. It then gives a simple verdict: pass for exactly 1200×630, ok for a ratio within 5% of 1.91:1 that is large enough, and adjust otherwise. It also warns when a file exceeds 8 MB, the practical upload limit for many platforms. If a URL cannot be loaded (for example due to cross-origin restrictions), the tool shows a friendly message instead of failing, and you can simply upload the file from your computer instead.

Once your image passes, make sure the page itself references it correctly. Head back to the meta checker to confirm your og:image tag is present, or review the full SEO meta checklist to cover every tag.
