How to reduce image size for email
Email providers limit attachment size, and large camera images waste bandwidth. Resizing dimensions first and then applying moderate compression usually gives the best balance.
Step by step
Resize oversized photos
For normal viewing, a longest edge around 1600–2000 pixels is usually enough.
Compress a copy
Use JPG or WebP quality around 75–85 and compare the preview with the original.
Check the final total
Leave room for message content and provider overhead instead of targeting the exact attachment limit.
Useful tips
- Resize before lowering quality aggressively; fewer pixels often saves more with less visible damage.
- Do not overwrite your only full-resolution copy.
