What is HEIF file format?

HEIF (High Efficiency Image File Format) also known as HEIC (High Efficiency Image Coding) is a graphic format which is not as popular as JPG, JPEG, PNG, and GIF, the most commonly-used image formats in the world. Apple introduced the HEIF file format in iOS 11 to replace the original JPG format. It was first defined in 2013 and completed in 2015. One of the best advantage over JPG and JPEG format is it can reduce the file size while ensuring a better quality image. The default file extensions are HEIC and HEIF. Relatively, the most frequently-used file format is HEIC.

HEIF vs. HEIC

As we just stated, HEIF and HEIC are the filename extensions of HEIF image. However, there are difference between HEIF and HEIC file type. HEIF is a file format for storing individual images and sequences of the image, while the HEIC file can store both image and video files, for example, the live photos.

HEIF vs. JPEG

HEIF image file format stores twice as much data as JPEG images when they are in the same size, which can help to produce a better quality image. If JPEG can only capture color in 8-bit, HEIF is able to increase it to 16-bit. HEIF file format can hold multiple images, audio, image thumbnails, depth-of-field information and much more, while JPEG, in contrast, can only carry data for one photo. The coming table can help you get an intuitive comparison between them.
