What is HEIC?
If you have ever moved photos from an iPhone to a computer, you have probably seen files ending in .HEIC. This guide explains what the format is, why it does not always open, and how to get a familiar JPG or PNG.
Updated: November 2, 2026
What is HEIC
HEIC (High Efficiency Image Container) is an Apple image format introduced in iOS 11. It uses the HEVC codec, so a photo takes roughly 30–50% less space than a comparable JPG. iPhone and iPad save photos as HEIC by default to save storage.
The container can hold more than one image, metadata and Live Photo data. For most people it is simply an iPhone photo that does not always open outside Apple’s ecosystem.
Why HEIC does not open on Windows or in older apps
The problem is the missing codec, not the file itself. Windows 10 and 11 do not support HEVC/HEIF out of the box: you need the HEIF Image Extensions and HEVC Video Extensions. Older versions of Photoshop, office suites and image viewers may also fail to open HEIC.
Android supports HEIC only partially, and many messaging apps and websites still accept JPG or PNG only. That is why converting before sending is often the easiest fix.
How to open HEIC
There are three practical options:
- Install the HEIF/HEVC codecs on your system.
- Open the file in an app that supports HEIC.
- Convert the photo to JPG or PNG.
Our HEIC to JPG and HEIC to PNG converters decode the file in your browser with heic2any. In most cases the photo never leaves your device, which matters when the images contain personal data.
HEIC or JPG?
HEIC is better for storage on an iPhone: smaller files at good quality. JPG is more convenient for sending, publishing and opening on Windows. Choose PNG if you need transparency or repeated lossless editing.
If you are unsure, keep the original HEIC in your archive and use a JPG copy for everyday tasks.
Questions and answers
Is HEIC a photo or a video?
It is usually a photo. The HEIC container can also store a Live Photo, multiple frames and metadata, but in most cases you are dealing with a single image.
Why does Windows not open HEIC?
Windows does not include the HEVC/HEIF codec by default. You need to install the HEIF and HEVC extensions from the Microsoft Store or convert the file to JPG.
Does converting to JPG reduce quality?
JPG uses lossy compression, but at high quality the difference is usually invisible. Keep the original HEIC if you need an archive copy.
Can Android open HEIC?
Recent Android versions support HEIC partially, but not every app can open it. Converting to JPG solves the compatibility problem.
