Upload Errors and File Size Limits for SMS and MMS Messages
An upload error is frustrating when the message is vague. Picture messages on many carriers are limited in size, and oversized images may be shrunk heavily or fail to send.
Recommended settings for SMS and MMS messages
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1024 px on the long edge |
| Quality | 78 |
| File size | 250 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Upload Errors and File Size Limits
Most errors come from three causes: the file is too big, the dimensions are outside the allowed range, or the format is not accepted.
For SMS and MMS messages, convert to JPEG, resize to about 1024 pixels and compress below 250 KB. If the form lists its own limits, use those numbers instead.
