OG Image Size Checker — free online tool

You picked a nice picture for your post, but when you shared the link it looked cropped or blurry. The reason is usually the image size: social sites want a specific shape, and yours didn't match. We added a free tool that checks it for you — OG Image Size Helper — right in your browser.

What it does

Drop in any image and it tells you whether it meets the recommended Open Graph and Twitter Card size (1200×630 px). You'll see the aspect ratio, the file size, and the actual width and height, so you know at a glance if the picture is ready to share or needs a quick fix.

Nothing leaves your device

The whole thing runs in your browser. Your image isn't uploaded anywhere, nothing is saved, and nothing is sent to us. When you close the tab, it's gone. You can use it on photos you'd never want online.

How to use it

  1. Open OG Image Size Helper and add your image.
  2. Look at the size, aspect ratio, and file size it shows.
  3. Use the result to confirm it fits, or swap the picture and check again.

It's free with no limit. There are more small tools on the Apps page.
