🖼️ Open Graph Image Size Checker

Find a page's og:image or inspect image URLs and local files. Check browser-reported dimensions, aspect ratio and a configurable share-image reference, then copy optional Open Graph dimension tags.

Webpage URL

ToolMint's protected endpoint reads the page's Open Graph image URL. Your browser then loads that image to measure its dimensions.

Comparison reference

Choose pixel dimensions to compare against. This is a configurable reference, not a platform acceptance guarantee.

Common wide-share reference

1200 × 630 px · about 1.91:1

Ratio comparison accepts a difference within 3% of the selected reference.

📐 What this checks

The browser decodes the image and reports its intrinsic width and height. The configurable reference compares pixel dimensions and aspect ratio; it does not emulate every social platform's crawler, crop, cache or acceptance rules.

🔐 Privacy and limits

Uploaded files stay in your browser. For image URLs, your browser requests the image host directly; webpage mode uses ToolMint's protected metadata endpoint and then loads the image in your browser. Open Graph width/height are optional structured properties, not proof that a social platform will display an image as expected. Open Graph Preview Generator
