How to Compress JPEG for SMS and MMS Messages

Updated August 22, 2026 · 9 min read

Getting a JPEG ready for SMS and MMS messages is mostly about two numbers: pixel width and file size. 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

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1024 px on the long edge
Quality78
File size250 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

How to Compress JPEG

Start by resizing. A photo straight from a phone is often 4000 pixels wide, while SMS and MMS messages rarely benefits from more than about 1024 pixels. Halving the width cuts the pixel count to a quarter, which shrinks the file far more than any quality slider.

Then set quality. For SMS and MMS messages, a quality around 78 keeps edges and skin tones natural while removing detail your eye will not miss. If you have a hard cap, type it into the target size box and let the compressor search for the highest quality that fits under 250 KB.
