Open Graph Image Size Checker
Check local social sharing image dimensions before publishing. Review 1200 x 630 px fit, aspect ratio, minimum width, and file size without uploading the image.
An Open Graph image size checker reads a local image and checks whether it fits common social card dimensions.
It is useful before attaching an image to og:image, Twitter cards, or social preview metadata.
Final exports
Use the exact PNG, JPG, or WEBP you plan to publish as a social image.
Preview images
Check blog, tool, docs, product, and landing page sharing graphics.
The tool checks dimensions, width, approximate 1.91:1 aspect ratio, and practical file size guidance.
It does not upload files, fetch remote images, or guarantee exact cropping on every social platform.
Use this before Meta Tag Previewer when preparing Open Graph images for pages, articles, and tool launches.
After deployment, use live social card debuggers to confirm how platforms render the final URL.
Blog cover QA
Check a post image before adding it as og:image.
Tool launch cards
Verify sharing graphics for tool pages and product updates.
CMS image review
Confirm image dimensions before uploading assets into a CMS.
Design handoff
Give designers a simple size check for social preview exports.
Example
A 1200 x 630 px PNG passes the common Open Graph size and ratio checks.
Assumption
The selected local file is the same image you plan to publish.
Limitation
The tool does not inspect remote URLs, cache state, platform-specific crops, or social debugger results.
Does this upload the image?
No. The image is read locally in the browser.
What size should I target?
1200 x 630 px is a common Open Graph image target.
Can it check a remote URL?
No. This version checks local files only to stay fully browser-side.
Can platforms still crop the image?
Yes. Different platforms and layouts can crop or scale previews differently.
Suggested workflow
Social preview image path
Prepare the image dimensions, check Open Graph fit, and preview the metadata before publishing.
