The fastest way: use the Photos app inside Mail

Open the Mail app and start a new message or reply to one. Tap in the body of the email where you want the image to go. Then tap the arrow icon at the bottom left of the keyboard — it looks like a curved arrow pointing up and to the right. A menu will appear with options including "Photo Library". Tap that, and your Photos app will open inside Mail so you can pick the image without leaving the email.

Once you select a photo, Mail will ask what size you want to send it at. Choose "Small", "Medium", "Large", or "Actual Size". Smaller sizes send faster and take up less space in the recipient's inbox. Most people choose "Medium" unless the image needs to be very clear or very small. The image will drop into your email body, and you can send it normally.

Key Takeaways

  • Tap the arrow icon at the bottom left of the keyboard in Mail, then choose "Photo Library" to insert an image without leaving the email.
  • You can also take a photo directly inside Mail by tapping the arrow and choosing "Take Photo" instead of picking an existing one.
  • Smaller image sizes send faster — "Medium" works for most emails unless the recipient needs the full resolution.
  • If you want to send multiple images at once, attach them one at a time using the same arrow-menu method.

Taking a photo directly inside an email

You do not have to pick an existing photo. If you want to take a new picture and attach it right away, tap the arrow icon at the bottom left of the keyboard, then tap "Take Photo". Your camera will open. Take the shot, review it, and tap "Use Photo" to insert it into the email.

This is faster than taking a photo in the Camera app, finding it in Photos, and then attaching it. The image goes straight into the email at the size you choose.

Attaching multiple images to one email

Mail does not have a "select multiple" option in the photo picker. Instead, attach images one at a time. Tap the arrow icon, choose "Photo Library", pick the first image and set its size, then tap the arrow again and repeat for the second image. Each one will appear in the email body in the order you add them.

If you are sending many images, consider whether the recipient really needs all of them, or whether a few key ones will do. Large emails with many photos can take a long time to send on slower connections and may bounce back if your email provider has a size limit.

What to do if the arrow icon does not appear

The arrow icon only shows up when your keyboard is visible. If you do not see it, tap in the email body to bring the keyboard up. Make sure you are tapping in the message text area, not in the "To:" or "Subject:" fields.

If you are using an older iPhone or an older version of iOS, the arrow menu may look slightly different, but the "Photo Library" option should still be there. Tap and hold on the text area if a single tap does not bring up the keyboard.

Sending images as attachments instead of inline

The method above puts images directly into the email body. Some email programs and phones handle this differently — the image might appear in the message or as a separate attachment depending on what the recipient uses to read email.

If you need the image to be a true attachment that the recipient can save separately, Mail on iPhone does not give you a separate "attachment" button the way some email programs do. The image will be embedded in the message. If the recipient needs a file they can read and save, they can usually right-tap the image and choose "Save Image" from their own email app.

Image size and file format on iPhone

When you choose "Small", "Medium", "Large", or "Actual Size", Mail compresses the image for you. You do not have to resize it yourself or convert it to a different format. iPhone photos are usually in HEIC format, but Mail converts them to a format that works in email automatically.

If the recipient says they cannot open the image, it is usually because their email program or device does not support the format, not because anything went wrong on your end. Ask them to try opening it in a different app, or resend it using "Large" instead of "Actual Size" — sometimes a smaller file size helps.

Troubleshooting when images will not attach

If tapping the arrow does nothing, try closing Mail and opening it again. If the photo picker opens but you cannot see your photos, check that Mail has permission to access your Photos app. Go to Settings, scroll down to Mail, tap it, and look for "Photos". Make sure it is set to "All Photos" or "Selected Photos", not "None".

If Mail keeps crashing when you try to attach an image, restart your iPhone. If that does not work, try deleting and reinstalling Mail — though this is rare. Most attachment problems are solved by closing and reopening the app or checking permissions.

Frequently Asked Questions

Can I attach a screenshot to an email on iPhone?

Yes. Screenshots are saved to your Photos app automatically. Use the arrow-menu method to pick the screenshot just like any other photo. It will attach the same way.

What is the biggest image I can send?

That depends on your email provider, not on iPhone. Most providers accept emails up to 20 to 25 megabytes. A single photo at "Actual Size" is usually a few megabytes, so one or two images are fine. If you are sending ten images at full resolution, you may hit the limit.

Will the recipient see the image in the email, or as an attachment?

It depends on their email program. Most modern email apps show images inline in the message. Some older programs or very strict corporate email systems may show it as a separate attachment. Either way, the recipient can see and save the image.

Can I attach images from iCloud Photos or Google Photos?

Only if they are also in your iPhone's Photos app. Mail's photo picker only accesses your local Photos library. If a photo is stored only in iCloud or Google Photos and not downloaded to your phone, you will not see it in the picker. read it first, then attach it.

Why does my image look blurry after I send it?

You probably chose "Small" or "Medium" size. Try sending it again at "Large" or "Actual Size". The smaller sizes compress the image more to send faster, which can make it look less sharp on the recipient's screen.
