Frequently Asked Questions
What's a reasonable image attachment size for email?
Most email services cap attachments at 20–25MB. Photos under 1MB each make emails send fast and open easily.
What quality should email photos be?
70–80% quality is fine for on-screen viewing. Use higher quality if the photo will be printed.
Can I compress several images for one email?
Yes. Compress all the images at once, then attach the results to your email.
