Compressing Portrait Photos for Email Attachments
Faces are where viewers notice compression first. Mail providers cap attachment size and big photos slow down both sending and opening, so a lighter file reaches the inbox faster.
Recommended settings for email attachments
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 500 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Compressing Portrait Photos
Smooth skin and soft backgrounds can show banding at low quality. Quality around 78 to 85 keeps tones natural.
Crop to head and shoulders when the image is shown small, as it often is for email attachments. A tight crop lets you use fewer pixels without losing detail where it matters.
