Check the image file before metadata work
Open Graph previews start with a source image. If that image is too small, the wrong shape, or exported from a compressed preview, the URL debugger cannot fix the visual result.
Use this page for the file-level check, then use the full Open Graph image size guide for metadata, source, and update notes.

Upload a website preview image and compare it against 1200 x 630 or a larger 1.91:1 source image.

Open Graph preview checker FAQ
What size should an Open Graph preview image be?
A practical default is 1200 x 630 pixels, about a 1.91:1 ratio. Use the platform-specific guide for additional metadata and crop notes.
Does this checker validate my website metadata?
No. This page checks the image file dimensions locally. It does not crawl your URL or validate og:image tags yet.
Why does my preview image crop even at the right size?
Different platforms can crop thumbnails, round corners, or compress previews. Keep text and logos away from the outer edges.
