| Introduction | The Apple Icon Image format is an icon format used in Apple Inc.'s macOS. It supports icons of 16 x 16, 32 x 32, 48 x 48, 128 x 128, 256 x 256, 512 x 512 points at 1x and 2x scale, with both 1- and 8-bit alpha channels and multiple image states (example: open and closed folders). The fixed-size icons can be scaled by the operating system and displayed at any intermediate size. | JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. |
| Technical details | The file format consists of an 8 byte header, followed by any number of icons. Over time the format has been improved and there is support for compression of some parts of the pixel data. | Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange. |
