In this article, you will find a list of the image/design specifications for all of our app pages. As a general rule, the maximum for all images is typically 810 pixels wide by 1200 pixels tall, but some sections have different limits, as you’ll see below.
In the current version of your Woobox builder, you can add Image Elements to any page of your campaign. The maximum file size you can upload to an Image Element is 1MB (1,000kb).
The maximum file size for Backgrounds in the Customize section is also 1MB (1,000kb).
Updates have been made to Facebook share dialog. Here is what Facebook says about share images in their ‘best practices’ document:
“Use images that are at least 1200 x 630 pixels for the best display on high resolution devices. At the minimum, you should use images that are 600 x 315 pixels to display link page posts with larger images. Images can be up to 8MB in size.”
If your image is smaller than 600 x 315 px, it will still display in the link page post, but the size will be much smaller.
We’ve also redesigned link page posts so that the aspect ratio for images is the same across desktop and mobile News Feed. Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping.
The minimum image size is 200 x 200 pixels. If you try to use an image smaller than this you will see an error in the Sharing Debugger
The maximum specs for a share image in your Woobox offer are 810px by 1200px with 400KB file size.

GETTING AROUND THESE LIMITS
While 810 pixels is the maximum width of the Facebook display, you can definitely have larger widths – but we do not suggest adjusting it wider if you are installing it as a Facebook Page Tab (the Facebook tab is only 810 px wide).
To adjust the width limits, go into the customization section of your offer. On the left sidebar click “Styles. Then expand the advanced options.
