Compressing Product Photos for Email Attachments
Product photos must look accurate because people judge the item by them. 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 Product Photos
Shoot on a clean background, crop tightly, and resize to about 1600 pixels. Clean backgrounds compress extremely well.
Check colour and texture after compressing. For email attachments, a slightly larger file that shows the product clearly beats a tiny one that hides detail.
