What is a HEIF (High Efficiency Image File Format) file?

HEIF, which stands for High Efficiency Image File Format, is a modern multimedia container specification established by the Moving Picture Experts Group (MPEG) under the ISO/IEC 23008-12 standard. Carrying the .heif or .hif file extensions, it encapsulates individual images, image burst sequences, and metadata using advanced video compression codecs like HEVC. It provides high-depth color gradations, transparency, and HDR tonal ranges at roughly half the file size of legacy JPEG files.

How to open and view a HEIF file?

HEIF files can be opened natively on macOS, iOS, Android 9 and newer, and modern Windows operating systems equipped with HEIF codecs. Photo applications such as Adobe Photoshop, Lightroom, GIMP, and darktable also offer comprehensive HEIF reading capabilities.

If you need to convert your pictures into lightweight HEIF files to save storage space while maintaining pristine visual quality, our private client-side converter processes your images instantly inside your web browser without uploading files to remote servers.
