Image files that employ JPG compression are commonly called "JPG files" and are stored in variants of the JIF image format. JPG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography. HEIF also supports animation and can store more information than an animated GIF at a small fraction of the size. The MPEG group claims that twice as much information can be stored in a HEIF image as in a JPEG image of the same size, resulting in a better quality image. It was developed by the Moving Picture Experts Group (MPEG). In other words, HEIC should help you future-proof your memories.High-Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. Space savings aside, the technical advantages of HEIC images can play a factor years down the road. Unless you have severe compatibility issues among your devices, we recommended sticking to HEIC over JPG. Similar options should also be present on other HEIC (or HEIF) supported photo capture devices. On the iPhone, for example, head over to Settings > Camera > Formats and select Most Compatible to change the camera’s capture setting from HEIC to JPEG. You can still switch back to shooting in the JPEG format. On the iPhone, that should automatically happen while sharing images without you even noticing. But, it’s relatively easy to convert HEIC files to JPG as and when needed. You do have compatibility issues to deal with. You get incredibly lower-sized images at nearly, if not better, quality than JPEGs. HEIC is the superior format in almost every way. That should help it gain more traction over time. On another positive note, newer versions of photo-editing software such as Adobe Lightroom, GIMP, and Pixelmator have begun supporting the HEIC format. Due to licensing issues, though, the HEVC codec needed to decode HEIC images costs $0.99. In Windows 10, for example, you must download the relevant codecs separately from Microsoft. But, there are lots of asterisks involved. Most platforms outside the Apple ecosystem also support the format. JPG – CompatibilityĪny iPhone or Mac running iOS 11 or macOS High Sierra can open HEIC images. On the other hand, the JPG version of a Live Photo comprises a still image and a 3-second MOV video clip that uses up more storage space. With Apple’s Live Photos, for example, the format can save subtle differences in frames instead of capturing separate images. HEIC is also much better at capturing image sequences. Still, you end up with terrific-looking images at just half the file size. Apple’s smartphone cameras, for example, are limited to capturing images in 10-bit color. The features above apply to the HEIF format in general and not necessarily to the HEIC variant of images shot on the iPhone.
