Heif Format Vs Jpg Format

JPEG has reached its limits, especially since the image format can only use the
computing power of modern processors in a limited manner. If JPEG is highly compressed, it is always accompanied by a huge loss of details, which is not really ideal with photographs.
The animation format, GIF, which is currently celebrating a comeback in social networks, was also never a proven compression specialist.

1.  A new format for a more portable web In times of bandwidth excesses, poorly compressed images would not have been worse off. However, inefficient file formats automatically bring about high costs to the booming mobile web and Cloud storage services. The new High Efficiency Image File Format, HEIF, breaches this gap. This format was defined by the Moving Picture Experts Group (MPEG) and is based on the video codec H.265. Simply put, a HEIF image is a still image of an H.265 video. The format with the suffix ‘‘heic” reduces the file size by 40 to 50 percent in comparison to JPEG or GIF, while maintaining the level of detail. One can get an idea about the performance on the project website: nokiatech.github.io/heif. HEIF was brought into the limelight by Apple, as the company of experts announced the use of the file format for image storage in the macOS High Sierra and iOS 11. However, not every iPhone or iPad can generate images in HEIF. For mobile phones, it works only the iPhone 7 and onwards. The rule of thumb is that if the device generates 4K videos and supports H.265, it can also create HEIF images. 
2. The compression specialist HEIF is designed in a completely different manner as compared to JPEG (see graph), since it uses the compression of H.265 or HEVC, which again constitutes a direct continuation of the predecessor codec H.264. Technically, the formats are siblings, except that all essential compression procedures have been improved as compared to H.264. Both codecs use an image projection for pixel regulation. For example, in an image of an area of blue sky, entire chunks of pixels are combined and assign the value ‘‘blue” to them as a whole, rather than for each individual pixel. While H.264 packs blocks of maximum 16 x 16 pixels size, H.265 can now project blocks six times bigger, or a maximum of 64 x 64 pixels. When it comes to image contents with static and same-colour surfaces – such as clouds, shadows or meadows – a lot more can now be condensed, which ultimately reduces the file size by a considerable extent. 
3. HEIF can replace several formats As HEIF can also combine multiple images in one file, it can also technically replace the GIF format in its entirety. Moreover, apart from GIF, a HEIF file can also include short videos with audio. The same applies to the PNG format, whose strength lies in its transparent Background, a feature that HEIF provides as well. The new format supports simple image processing also, such as rotation or cropping without using additional tools (see table to the right). 
4. Apple stands alone With HEIF support, Apple has taken a bold step with its solo effort, which is not unusual for the company, but is posing problems for its users at the moment. This is because no other device apart for the current iPhones, iPads and Macs can support that file format yet. A HEIF image is thus unreadable on a Windows PC and there is also no commercial software available that could enable this. HEIF is currently supported only in the preview App and a few pictures viewers on Macs as well. Even Adobe has not yet announced any plug-in for its suite of software, which makes the processing on a PC practically impossible. Mind you, Apple seldom announce something so traditional, but releases it directly. It is also known to Apple that most of the users can use HEIF only on new iPhones, which is why there is now only one option in the camera settings with which the images can be converted to JPEGs before they are sent. 
5. Ideal for cameras and the web With its flexibility and performance, HEIF would also be an ideal storage format for digital cameras, camcorders and action cams. This is because the format has one more advantage. Even if the file sizes are the same, HEIF files will show more level of detail than JPEG files. However, there hasn’t been any concrete info regarding this topic from manufacturers yet. Even web developers are beginning to grow curious of the format. As it is a genuine all-rounder, HEIF can replace almost all conventional formats and make the websites more streamlined, which is not an unimportant factor for Google ranking. However, no browser has been able to feature HEIF images without the help of a JavaScript decoder – including High Sierra’s Safari browser. Having said this, JPEG and GIF did not become standard formats overnight either, so it might be some time before we see HEIF rise into prominence.
