What Is HEIC
HEIC is Apple's space-saving photo format used by iPhones, and this guide explains why it saves space and how to convert it for sharing.
On this page
HEIC is the photo format your iPhone saves pictures in by default. It packs the same image quality as a JPG into a much smaller file, which is great for storage but can cause headaches when you share photos with other devices.
Quick answer
HEIC (High Efficiency Image Container) is Apple's name for HEIF, a modern image format that stores photos at roughly half the file size of a JPG with no visible loss in quality. iPhones and iPads have used it since iOS 11. The catch is that many apps, websites, and Windows or Android devices cannot open HEIC, so you often need to convert it to JPG or PNG before sharing.
What HEIC and HEIF actually are
HEIF stands for High Efficiency Image File Format, an open standard for storing images. HEIC is simply the file extension Apple uses for HEIF files that hold a single still photo, which is why your iPhone pictures end in .heic. The two terms are used almost interchangeably in everyday life.
What makes the format modern is the compression behind it. HEIC uses the same kind of encoding found in efficient video, which squeezes far more detail into each file than the older JPG method. It can also store extras that a plain JPG cannot, such as depth maps, Live Photo motion, image sequences, and transparency.
Why HEIC saves so much space
The headline benefit is size. A HEIC photo is usually about half the size of the same shot saved as a JPG, at the same visual quality. On a phone holding thousands of pictures, that difference adds up to gigabytes of saved space and faster iCloud backups.
It manages this through smarter, more efficient lossy compression than JPG was designed for years ago. Smaller files also mean quicker uploads and less data used when photos sync to the cloud. For an Apple user staying inside the Apple world, HEIC is almost always the better choice and there is no reason to change it.
The compatibility problem
Efficiency comes at a cost: support. HEIC is well handled on recent Apple hardware and modern macOS and Windows, but it still trips up plenty of places. Older laptops, many Android phones, lots of websites, email clients, and design tools either refuse the file or show nothing at all.
This is the moment most people first hear the word HEIC, usually when they email a photo and the other person cannot open it. JPG, by contrast, opens almost everywhere, which is exactly why converting is so common. If you frequently share photos with non-Apple users, you can also turn off HEIC at the source: on iPhone, go to Settings, then Camera, then Formats, and choose "Most Compatible" to capture JPG instead.
Converting HEIC to JPG or PNG
When a HEIC file will not open somewhere it needs to, converting is the fix. JPG is the right target for almost all sharing, since it is universally supported and keeps files reasonably small. Use our HEIC to JPG converter to turn iPhone photos into files that open on any device, app, or website.
Choose PNG when you need a lossless copy for editing, graphics work, or transparency rather than casual sharing. PNG freezes every pixel without further compression, so it is heavier but ideal as an editing master. Our HEIC to PNG converter handles that in one pass. For switching between the more common web formats, the broader image converter tool covers PNG, JPG, and WebP.
After you convert
A JPG made from a HEIC source is larger than the original, since JPG is less efficient. If size matters for a website or an email, run the result through our image compressor to shrink it without an obvious quality drop. To change the dimensions for a profile picture or banner, the image resizer sets exact pixel sizes.
Keep one thing in mind: converting from HEIC drops the Apple-only extras, such as depth data and Live Photo motion. The flat image looks identical, but those features do not carry over to JPG or PNG, which is a fair trade when the goal is a file that simply opens everywhere.
Checklist
- Staying on Apple devices? Keep HEIC and save space
- Sharing with Windows, Android, or the web? Convert to JPG
- Need a lossless editing master or transparency? Convert to PNG
- Set iPhone to "Most Compatible" to capture JPG from the start
- Compress a converted JPG if file size matters
- Expect HEIC extras like depth and Live Photo to be lost on conversion
FAQ
Is HEIC better than JPG?
For storage, yes. HEIC holds the same image quality as JPG in roughly half the file size, and it can store extras like depth and transparency. JPG only wins on one crucial point: it opens almost everywhere, while HEIC support is still uneven.
Why can't I open a HEIC file?
The device or app you are using does not support the format. HEIC works smoothly on recent Apple gear and modern systems, but older computers, many Android phones, websites, and email clients cannot read it. Converting to JPG solves it instantly.
Does converting HEIC to JPG lose quality?
There is a small, usually invisible loss, since JPG re-encodes the image with its own lossy compression. For viewing and sharing it looks identical. If you want a lossless copy instead, convert to PNG, which keeps every pixel.
Will I lose my Live Photo or depth effect?
Yes. Those are Apple-specific extras stored inside the HEIC container, and a plain JPG or PNG cannot hold them. The still image converts perfectly, but the motion and depth data do not carry over.
How do I stop my iPhone from saving HEIC?
Open Settings, tap Camera, then Formats, and choose "Most Compatible." Your camera will save new photos as JPG, which open anywhere. Existing HEIC files stay as they are, so convert those separately when you need to share them.
