Lossy vs Lossless Compression for SMS and MMS Messages
Image compression comes in two flavours. 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.
Lossy vs Lossless Compression
Lossless compression, as in PNG, keeps every pixel exactly and saves modest space. Lossy compression, as in JPEG and WebP, discards detail the eye barely notices and saves far more.
For photographs used for SMS and MMS messages, lossy is the practical choice. Save lossless formats for graphics where every pixel edge matters.
