Email limits, October 2026
How many photos can you send in an email?
There is no photo limit, only a size cap: about 4 to 6 photos of 4 MB fit in a 25 MB email (Gmail, Outlook.com, Yahoo Mail), 3 to 5 in iCloud Mail's 20 MB. For 100 photos or more, shoots.page puts them behind one gallery link, free up to 2 GB, with no account needed to open it.

About how many photos fit in one email
| Photo size | 25 MB email | iCloud Mail, 20 MB |
|---|---|---|
| 2 MB | About 9 to 12 | About 7 to 10 |
| 4 MB | About 4 to 6 | About 3 to 5 |
| 8 MB | About 2 to 3 | About 1 to 2 |
Why the number depends on your photos
Email services don't count photos. They measure the size of the whole message, so the number you can send depends on how big each file is. The same 25 MB holds a dozen small photos or two large ones.
There is also a hidden cost. Email encodes attachments as text, and Microsoft's documentation says that makes a message about 33% larger. 18 MB of photos becomes about 24 MB on the way out, so keep your photos to about three quarters of the limit: about 18 MB for a 25 MB email, about 15 MB for iCloud Mail. The other end matters too. Apple notes that the recipient's email app might have a smaller size limit that stops the attachment from arriving.
Attach several photos at once
iPhone
Open the Photos app, tap Select, tap the photos you want, tap the Share button and choose Mail. If the email is bigger than your account allows, Mail offers to send the photos with Mail Drop instead.
Gmail
On a computer, click Compose, click Attach at the bottom, select the photos and click Open, or drag them into the compose window. In the Gmail app, tap Compose, then Attach at the top right, and pick photos up to 5 at a time. Repeat to add more.
Outlook.com
Select Attach, then Browse this computer. Hold Ctrl (Command on a Mac) to select several photos and select Open. You can also drag the photos into the message.
When you have 100 photos or more
Attachments stop making sense fast. 100 photos of 4 MB come to about 400 MB, which is about 17 to 25 separate 25 MB emails. 250 photos are about 1 GB, or about 42 to 63 emails. Nobody wants to receive that.
Send a link instead. Gmail already turns oversized attachments into a Google Drive link, Outlook.com shares files from OneDrive, and iPhone Mail offers Mail Drop for up to 5 GB, with 30 days to download. Those are the right picks for a mix of photos and videos.
For a photo set going to a group, where each person only wants the shots they are in, a gallery link is easier on the people opening it. With shoots.page you upload the photos once and paste one link into your email. Recipients open a grid of thumbnails, 60 per page, with no account, app or sign-up, and save single photos or the whole set as a ZIP when you allow downloads. It is free up to 2 GB per account, about 500 photos of 4 MB, and it takes photos only, no video. If your photos are too big to attach at all, read photos too large for email.
