Modern smartphones take photos that are 3-12 MB each. When you try to attach multiple photos, you quickly hit the email size limit. Here's what each email provider allows:
| Email Provider | Max Attachment Size | Photos You Can Send (5MB each) |
|---|---|---|
| Gmail | 25 MB | ~5 photos |
| Outlook / Hotmail | 20 MB | ~4 photos |
| Yahoo Mail | 25 MB | ~5 photos |
| iCloud Mail | 20 MB | ~4 photos |
| ProtonMail | 25 MB | ~5 photos |
After compressing, those same 5MB photos become 500KB-1MB each — meaning you can send 20-40 photos in a single email instead of struggling with 5.

Tips to Compress Photos to Email Even Smaller
- •Use JPG format — JPG compresses much better than PNG for photographs. If your photo is a PNG, convert it to JPG first.
- •Resize before compressing — A 4000px wide photo resized to 1920px will be dramatically smaller. Use our image resizer first.
- •Batch compress — Upload all photos at once to save time. Our tool handles multiple files simultaneously.
- •Try WebP format — WebP files are even smaller than JPG. Convert to WebP if the recipient's email client supports it.
- •Split across multiple emails — If you have 50+ photos, send them in batches of 10-15 per email to stay well under limits.
