What Size Should My Picture Be? (MMS Specs)

If you are looking to send a picture in your outbound campaign, it's wise to understand the requirements for best quality. When sending a picture, you can use formats such as JPG, GIF, and PNG. As far as sizes, you can use a max width and height of 1000 pixels. 

Anything beyond 600 pixels will be scaled down,thus making 600 pixels the preferred size. Max file size is 8 mb or lower. You may also include up to 1,600 characters of text in your campaign when sending an MMS message.

Because we do not resize animated GIFs, they will need to be under 490kb.

You're in excellent hands. We work with some of the world's greatest companies.
