JPG vs. HEIF

Have you noticed some pictures on i devices and in Windows 10 now have an extension of HEIF (High Efficiency Image File Format), instead of JPG (Joint Photographic Experts Group)?

It is a new designation for pictures and supports bonus features, such as it can accommodate live photos, bursts of photos, 3D scene data useful for special effects, audio, and more. As a container, HEIF can actually accommodate multiple compression technologies. When used with HEVC video compression, the resulting files are called HEIC images.

It compresses the file size to roughly half the size of JPG files to save space. The quality is reported to be identical.

Apple is using is also using it as a new standard, so you will be seeing more of these picture file types. Incidentally, it is usually pronounced heef.
