Convert HEIF to EXR Online For Free

HEIF (High Efficiency Image File Format) is an efficient image file format formulated by ISO (international standards organization). It uses advanced compression algorithms such as HEVC (High Efficiency Video Coding) to reduce the size of image files while retaining more image details and color information. HEIF files are actually a versatile media container that can store multiple types of data such as still images, moving images, audio, text, and metadata. Therefore, it is more flexible and versatile than traditional JPEG formats. In addition to smaller file sizes and higher image quality, HEIF supports other features such as transparency, depth images, and dynamic range images. This makes it more flexible and versatile in editing and sharing images. HEIF also supports combining multiple image and media files into a single file, thus simplifying file management and sharing. In addition, the HEIF format also provides longer battery life for mobile devices, as it requires less internet bandwidth and storage space. Although HEIF has become one of the mainstream image formats, not all devices and operating systems are able to properly process, display, or edit HEIF files. If you need to view or edit HEIF images on a device that does not support HEIF, you can convert them to another format, such as JPEG or PNG.

OpenEXR is an HDR standard developed by Industrial Light & Magic. OpenEXR file extension is .exr, the common OpenEXR file is FP16 (16bit Float Point, also known as half Float Point) data image file, the data type of each channel is FP16, a total of four channels 64bpp, each channel 1 bit bit is used to mark the "index", 5 bits are used to store the value of the index, 10 bits are used to store the mantissa of the chromaticity coordinates (u, v), and its dynamic range is from 6.14 × 10 ^ -5 to 6.41 × 10 ^ 4.
