Supported File Types and Carrier Limits
Before attaching files to your draft, review carrier file size and format requirements to ensure successful delivery.
| File Parameter | Platform Specifications | Carrier and Delivery Behavior |
| Supported Formats | JPG, PNG, GIF, and PDF | HEIC (Mac/iOS native photo format) and video files are not supported. |
| Image Size Limits | 5 MB maximum total size of all attachments | Images under 1 MB deliver at full resolution. Files larger than 1 MB are compressed automatically to meet carrier limits. |
| PDF Limits | 1 MB maximum file size | PDFs cannot be compressed automatically. Files exceeding 1 MB must be resized before uploading. |
| Attachment Count | 3 attachments per single message | Multiple image attachments are downsized automatically so the combined size does not exceed 5 MB. |
Warning: Not all mobile carriers support PDF delivery via MMS. Canadian carriers and select US mobile carriers will block messages containing PDF attachments. If deliverability to all recipients is required, convert your document to a PNG or JPG image, or share it via a web link.
