Guidelines for images and GIFs in your text message marketing

Static images should be in JPG format, while animated images should be in GIF format.



JPG is supported by most devices and renders the fastest. Keep the most important content in the middle of the image. Use a tall image with a 9:16 aspect ratio and no transparency:

  • 640 x 1138px (W x H)

  • 1080 x 1920px

Animated GIF

Use a square or tall image with the following dimensions, with no transparency:

  • 480 x 480 px (recommended)

  • 640 x 640 px

  • 480 x 640 px

  • 480 x 720 px

Image size

All images must be 500KB or less
