How to email photos from iPhone without quality loss

iPhone photos are easy to email: for the first three. After that the Mail app starts squeezing, HEIC starts confusing your recipient, and the whole thing bounces. Here's how to do it properly.

Method 1: share from the Photos app (1–3 photos)

1. Open Photos, tap Select, choose your photos.
2. Tap the Share button (square with the arrow).
3. Pick Mail.
4. The Mail compose window opens with the photos attached. A size picker (Small / Medium / Large / Actual Size) appears in the keyboard's accessory bar: pick a size based on how many photos you've added.

For two or three photos, "Large" is usually the sweet spot: recipients see a sharp image, message stays under the size limit. "Actual Size" is fine for a single photo; risky beyond that.

Method 2: attach from inside Mail

Already composing? Tap inside the body, then the insert icon (the one with a little plus in a circle, depending on iOS version) or use the keyboard's photo icon. Pick from your library. Same size picker applies.

Method 3: emailphotos.com in Safari (recommended for many photos)

For 5+ photos, the in-Mail experience gets fiddly: Mail won't tell you the actual total size until after you've picked, the size picker is one-size-fits-all, and HEIC conversion is unpredictable. EmailPhotos.com sidesteps all of that:

1. Open emailphotos.com in Safari (or any browser).
2. Tap the drop zone → Photo Library → select your photos.
3. Each photo compresses in a Web Worker. You'll see a live total like 11 MB / 14 MB at the bottom.
4. Tap Send. iOS opens the share sheet with all photos attached: pick Mail, Gmail, Messages, whatever you have.

Photos never leave your iPhone: compression happens in Safari's tab. HEIC is converted to JPEG automatically so any recipient can view them. EXIF and GPS are stripped by default for privacy.

The HEIC problem

iPhones save photos as HEIC by default: High-Efficiency Image File Format. They're about 30 % smaller than JPEG at the same quality, but a chunk of the world can't open them: Outlook, Yahoo Mail, Windows Photos, older Android Mail clients, anything pre-2018.

Your options:

• Let Mail convert. When you attach via Photos → Share → Mail with anything other than "Actual Size", iOS converts HEIC to JPEG. Stick with this for casual emails.
• Force JPEG capture. Settings → Camera → Formats → Most Compatible. This affects new photos only.
• Convert in the browser. EmailPhotos.com does this automatically. Useful for old HEICs already in your library.

iCloud Mail Drop: when it kicks in

If you attach more than 20 MB in Apple's Mail.app, iOS offers Mail Drop: photos upload to iCloud and the email contains a download link instead. Recipients click the link, download for 30 days. Up to 5 GB per email.

Quirks worth knowing:

• Mail Drop only works in Mail.app, not Gmail / Outlook / Yahoo apps on iPhone.
• Recipients on slow connections may struggle with the download.
• The link expires: bad if your recipient archives emails for later.

If you want real attachments rather than a link, compress the photos instead.

"Why can't I email photos from my iPhone?"

Common causes, in order of likelihood:

1. Total size over 20 MB. Mail bounces with a generic "couldn't send" error. Drop a few photos, choose a smaller size, or compress.
2. iCloud account out of storage. Mail uses iCloud SMTP. If iCloud is full, sending fails. Settings → [your name] → iCloud → Storage.
3. Mail account not signed in. Settings → Mail → Accounts.
4. Recipient blocking HEIC. Older corporate filters strip HEIC attachments silently. Convert to JPEG.
