24MP is the everyday choice; 48MP is for extra resolution
On supported iPhones, 24MP and 48MP are capture-resolution choices, not different HEIC formats. Use 48MP when you have a reason to keep more pixels, such as heavier cropping; 24MP is the simpler everyday option.
What 24MP and 48MP mean
Apple supports standard HEIF capture up to 24MP and HEIF Max up to 48MP on compatible iPhone models and camera modes. Both can still be HEIC/HEIF images; the number describes resolution.
Not every lens or shooting mode produces 48MP. Night mode, flash, macro, zoom, and device model can affect what resolution is available.
24MP vs. 48MP at a glance
Choose based on how you shoot, edit, and store your photos.
| What to compare | 24MP | 48MP |
|---|---|---|
| Everyday use | A practical default for everyday photos, with less storage use than 48MP in many situations. | Useful when you want more pixels for cropping or a larger final image and your iPhone supports the mode. |
| File size | Usually easier on storage than a 48MP photo from the same device and scene. | More pixels generally mean larger files, though the exact size still depends on the scene and camera settings. |
| Cropping | Enough resolution for many normal viewing and sharing needs. | Gives you more pixels to crop from when the extra resolution is actually captured. |
| Availability | Available on supported iPhones and camera modes. | Requires a compatible iPhone and capture mode; some conditions can reduce the available resolution. |
How to check the setting
On supported iPhones, Camera settings include format and resolution options, and compatible models can expose HEIF Max in the Camera app. The exact controls vary by model and iOS version.
For a photo you already took, check its pixel dimensions instead of assuming the resolution from the .heic extension.
When 24MP is a good fit
Choose 24MP for everyday photos when you do not expect to crop heavily and prefer smaller files and simpler storage.
When 48MP is worth using
Choose 48MP when the extra resolution has a clear purpose, such as stronger cropping flexibility or a larger final image. More pixels do not guarantee a better-looking photo in every scene.
Which should you choose?
For most casual shooting, 24MP is the easier default. Use 48MP when your iPhone supports it and you know you will benefit from the additional resolution.
HEIC 24 vs 48: bottom line
In a HEIC 24 vs 48 comparison, the main difference is resolution. 24MP is practical for everyday photos; 48MP gives you more pixels when you need extra crop room or larger output.
HEIC 24 vs 48 is not a choice between two file formats—the photos can use the same HEIC/HEIF family at different capture resolutions.

Frequently asked questions
Common questions about 24MP and 48MP HEIC photos.
No. 48MP gives you more pixels, but availability, file size, lighting, lens choice, and how you use the image all matter.
No. They are different capture resolutions. Both can be stored as HEIC/HEIF.
Some lenses and shooting modes do not use 48MP. The available resolution depends on the device, camera, mode, and shooting conditions.
24MP is a practical default for everyday use. Choose 48MP when you specifically want the extra resolution.
