An HEIC file is a file format used for storing digital images. HEIC stands for High Efficiency Image File Format, and it is part of the HEIF (High Efficiency Image File Format) standard. It was developed by the MPEG (Moving Picture Experts Group) to provide a more efficient way of encoding images compared to the more common JPEG format.
The HEIC format offers several advantages over JPEG, including:
- Higher Compression Ratios: HEIC can achieve smaller file sizes while maintaining similar image quality to JPEG. This is particularly beneficial for devices with limited storage space or for users who want to reduce the size of their image collections.
- Better Metadata Support: HEIC files can store more metadata, such as copyright information, camera settings, and location data, within the file itself, without the need for separate sidecar files.
- Lossless Compression: HEIC supports lossless compression, which means that the compressed file can be decompressed to its original state without any loss of image quality. This is useful for archiving or when exact original quality is crucial.
- Support for Multi-Frame HEIC: The HEIF standard also supports storing multiple images in a single file, which is useful for formats like HDR (High Dynamic Range) and panoramic images.
Apple was one of the first companies to adopt the HEIC format, and it is now default image format on iPhones, iPads, and Macs. However, not all devices and software applications support HEIC files, which can lead to compatibility issues. Many cameras and Android devices still save images in the JPEG format.
To address compatibility concerns, Apple devices have a built-in converter that automatically saves HEIC files as JPEG when you share them with non-compatible devices or software. Third-party software and online tools are also available for users to convert HEIC files to JPEG or other formats.
