MMS supported media formats and file size
Supported Media Formats
- gif (moving or static)
Maximum file sizes
You can send a single attachment with a file size of up to 250 kB. Some older devices can only accept attachments with up to 30 kB. If sending a gif image, we recommend keeping the file size below 100 kB.
Images are automatically resized (except for gif images). We recommend to keep the aspect ratio of an image to be as close to 1:1 as possible e.g. 300 x 300 px.
