Compress images that are too large for email
Most email providers limit attachments to 20-25MB, but a single camera photo can be 5-10MB. Compress to any target size and send without bouncing.

Email attachment limits by provider
Every email service caps how much data you can attach to a single message. The problem isn't one big photo — it's that modern smartphones shoot images at 5-15MB each, so attaching just 3-4 photos can exceed the limit instantly.
Gmail
Limit: 25MB total per message
A single 12MB iPhone photo uses nearly half your budget before you add text or other attachments.
Outlook / Hotmail
Limit: 20MB total per message
Even stricter than Gmail. Two uncompressed camera photos can already push you over.
Yahoo Mail
Limit: 25MB total per message
Same ceiling as Gmail, but some corporate recipients have lower incoming limits.
Apple Mail
Limit: 20–30MB (varies by provider)
Apple Mail warns you before sending, but the recipient's server may still bounce it.
Recommendation
Sweet spot: Compress each image to 500KB–1MB.
This lets you safely attach 20+ photos in one email without hitting any provider's limit.
Email image compression FAQ
How small should my image be for email?
For single images, 500KB-1MB is ideal. If attaching multiple photos, aim for 200-500KB each. This ensures you stay well within the 20-25MB total limit even with several attachments.
Does compression reduce image quality noticeably?
For email sharing (viewed on screens, not printed), compressing a 5MB photo to 500KB-1MB shows virtually no visible difference. The recipient sees a clear image that loads instantly.
Can I batch compress multiple photos for one email?
Currently you can process one image at a time. For multiple photos, simply repeat the process — each takes about 2 seconds. We're working on batch support.
