iOS 11 HEIF format make High definition photos and videos in a half size

With Apple we continue to welcome the future. Its powerful iOS 11 operating system uses the HVEC video format and the HEIF photo format to compress HD content and reduce it to half its current weight. Which means that we can now store more content on our smartphone and with better quality.
Let's explain a bit more about what this attractive improvement means. HEIF stands for "High Efficiency Image File Format" and is the still image version of the HVEC video format. As its name indicates it is a more efficient way of storing images, and with a loss of quality much smaller or almost null.

A kick to the past

iOS 11 chose to replace the traditional JPEG image format with the new HEIF format, which offers better compression of high-definition videos and photos. Through its modern methods, the photos stored in this new format weigh approximately half the size of JPEGs, and are of better quality.
As a notable advantage, this also translates into getting twice as much space to store larger and better multimedia content.

Restrictions and Compatibility

Only the latest Apple devices have built-in hardware support for HVEC and therefore HEIF. This means that not all iPhone will be able to compress photos and videos and reduce them by about 50% of their original size. Here we tell you if they can encode and decode the images super faster, without affecting the system or the battery:
  • iPhone 7 and iPhone 7 Plus.
  • iPhone 8 and iPhone 8 Plus.
  • iPhone X.
  • iPad Pro of 2017 10.5 and 12.9 inches.
  • Mac with Intel Core sixth generation.
Now, a very important point that we must clarify is that all devices with iOS 11 will be able to read and edit these formats. They will be able to view and handle HEIF and HEVC files as long as they are upgraded to iOS 11. But only those terminals that have specific hardware support will be able to record them.
Perhaps a frequent doubt can be this: If I have an iPhone X and I have stored an image type HEIF, can I share it to another device without problems? Yes, iOS artificial intelligence is the ultimate. You can share a photo in HEIF format and it will change format automatically. Thus the person on the other side will receive it in the standard JPEG, accepted in any device. The same will happen with the videos. Nothing to worry about.

High power of understanding

Format heif vs jpeg
HEIF, created by the MPEG Group, rather than a format is defined as a file container. It is a drawer that contains information about the photograph and encodes it quickly through the HVEC holder. Information that can now contain more than one frame, of course, to preserve the quality.
To understand the power of your compression, we explain it like this: a simple 12 megapixel image has gone from 2.1MB to 1MB, a Live Photo of 2.6MB to 1.3MB and a video of 20 seconds recorded in 4K and 30 frames per second , from 118.2MB to only 58.2MB. So now you will have twice the space to photograph and record whatever you want without worrying about space.
