How to Compress Images for Email Attachments
Why email image size matters
Most providers limit message size to 25 MB total, but large photos slow sending and trigger spam filters. Aim for 200–300 KB per image attachment for smooth delivery.
Recommended sizes
Profile photos: 100 KB. Document scans: 200 KB. Vacation photos: 250–500 KB. Use our Compress for Email tool for a ~250 KB target.
