You try to send a picture by text and get a “not delivered” error, or the recipient gets a blurry mess. It’s an annoying problem, and it comes from how text messaging handles pictures.
Why photos fail in text messages
Regular picture messages over SMS/MMS have strict size limits, and these vary by carrier and country. They are often around the 1 MB mark, though some allow more. A modern phone photo can be several times that. Apps like iMessage, WhatsApp and RCS-based messaging handle larger files by compressing automatically or using internet data, but when a conversation falls back to MMS, the limit applies.
Why they look blurry on arrival
To get under the limit, the phone or carrier compresses the image heavily, often more than you’d choose to. The result is noticeable softness and blocky edges. Resizing the picture yourself, before sending, gives you control over the trade-off.
The quick fix: shrink it first
For a picture that will be looked at on a phone screen, you don’t need more than about 1200 pixels on the long side. Shrinking a 4000-pixel photo to 1200 cuts the file size dramatically and keeps it clear on a phone display. Then save as JPG at quality around 75 to 80. The general approach is covered in how to reduce image file size.
Step by step on a phone
- Open a browser-based resizer, such as ours, on your phone.
- Choose the photo and set the width to 1200.
- Pick JPG and download it to your gallery.
- Attach the smaller copy to your message.

Other things you can try
- Send as a link. Upload to a cloud service and share the link instead. The recipient gets the full-quality original.
- Use a messaging app. WhatsApp, Telegram, Signal and others send over the internet and don’t face MMS limits.
- Check your data connection. MMS needs mobile data turned on, even when you’re on Wi-Fi, on many phones.
- Send fewer pictures at once. A batch of five might hit the limit that two wouldn’t.
Sharing photos where quality matters
If it’s a keepsake photo you want a family member to keep or print, don’t send a shrunk copy. Share the original via a cloud link, email attachment or a messaging option that preserves quality. For printing, you need the full pixels. See resizing images for printing.
Privacy tip
Photos can carry location data. Before sharing pictures widely, review what EXIF data is and how to remove it. Many phones have a toggle in the share sheet.
For HEIC photos
iPhone photos in HEIC format may not open on some other phones. If the recipient can’t view it, convert it first. See how to convert HEIC to JPG.
