A HEIC file contains one or more images and is usually created on an Apple device like an iPad or iPhone. Apple introduced the format in macOS High Sierra and in iOS 11. You may have problems opening HEIC files on your Windows PC, as not all versions of Windows have native support for these files.
HEIC is an acronym for High-Efficiency Image Container, which is an image format invented by Moving Picture Experts Group. It is used instead of the older JPEG format and has multiple advantages like smaller file size (without quality loss), option to store multiple images in one file (great for photo bursts), 16-bit color support, image revision history,
You may hear HEIF or HEIC used interchangeably, as the format invented by MPEG is really called HEIF (High-Efficiency Image Format). Why Apple decided to call files on their devices HEIC is unknown.
HEIF support was also introduced in Windows 10 with build 1809, released in October 2018. However, it doesn't come included out of the box. You will have to visit the Microsoft app store and install the Microsoft HEIF Image Extensions, and in addition to that, you will also need to install the HEVC (High-Efficiency Video Coding) Video Extensions package, as the Microsoft HEIF Image Extensions uses the decompression codec included in this package when displaying HEIF images.
Unfortunately we have not received enough suggestions for software that can open HEIC files yet.
File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the HEIC file format or software that uses files with the HEIC suffix, please do get in touch - we would love hearing from you.
