If you take many photos for personal archives or SMM projects, saving storage space is more relevant than ever. Because high-quality images have big sizes. One day, it may happen that the memory on your phone will be complete.

It can be at an unexpected moment, for example, when you will want to shoot a beautiful rainbow, or you need to take subject photos of a new cosmetic product for Instagram. Apple company, noticing this problem, has developed a new file type. This is a HEIC. It saves space in your gadget, allowing you to take many quality contents. What is the HEIC photo format? How does it differ from other photo formats? How to convert HEIC to JPEG? In the article, we will answer these and many other questions.

High-Efficiency Image Format: Main Features

You’re getting used to the fact that the photos made on your camera are saved on the device in JPG format. But starting with iOS 11 and newer operating systems, you notice that images are captioned as HEIC instead of the usual abbreviation. Why is the format called? Let’s find out further. 

What is the HEIC format?

HEIC stands for High-Efficiency Image File. It’s a new container format developed by the Apple company for modern models of the iPhone and iPad. It saves photos in higher quality than the popular format JPEG but simultaneously takes up very little space in the memory card on the device. This is due to modern compression technology. 

What does a HEIC file contain? It’s usually one image or sequence of iPhone photos you took with the device's camera. HEIC also includes metadata that describes every image. In particular, you can see information about the size of the image, location, resolution, editing, etc. Files of this format are saved as .heic or.HEIF. It all depends on the number of pictures inside. Image container HEIC functions as JPEG. You can edit, move, and convert HEIC extensions in other formats. 

The Compressing of a Photo: How it Happens?

The process of photo compression seems complicated at first glance. But in practice, everything is effortless. The container uses High-Efficiency Video Coding (HEVC) to save space on the memory card. This is a special codec that was developed initially for video compression. 

To reduce video file size, HEVC compresses every frame with discrete cosine and sine transforms (DCT and DST) with block sizes raining from 4×4 pixels to 32×32 pixels. It makes the image more accurate with an emphasis on details. During this process, inter-frame compression also occurs. Thanks to this, the codec compresses video more than the photo. However, it’s very effective in compressing images. 

How Much Space Can You Save due to HEIC?

The HEIC format allows you to save high-quality photos with twice less storage space. For example, to keep a good image in JPG format, you need 8 megabytes. HEIC requires only 4 megabytes. 

In this case, you can transfer photos faster than when using the JPEG format. And this will help you well when you require the captured photo content to process in Photoshop or other editors on your computer. 

HEIC and JPEG Formats: What is the Difference?

At first glare, the HEIC file format differs from JPEG because it takes up less space in the memory gadget. There are more differences here:

  • Compression features. Suppose you work with JPEG files and want to compress them while editing and re-storage. It may lead to the loss of some background data. And as a result, the picture quality will deteriorate. It doesn’t happen while compressing HEIC photos because, in this case, this format breaks images into essential files.

  • Picture quality. Despite smaller file sizes, the image quality remains at a high level. It even exceeds the rate of JPEG. It’s influenced by transparency and border dynamic range capabilities. 

  • Storage space. If you transfer a .HEIC file to your computer, it will take up little space, and, accordingly, the load on the hard drive will not be so high. JPEG files, on the contrary, take up a lot of space and if the drive is full of photos, the computer will slow down a bit. 

  • Transparency. JPEG files don’t support transparency. So, they don’t have suitable work related to creating design projects. The file extension HEIC, like PNG, gives more opportunities in this regard. Having transparency, such images merge seamlessly with the existing background of a webpage. Thus, web designers can quickly create logos, graphics, and other designer objects. 

  • Editing possibilities. With each new editing and downloading, the JPEG file loses its quality. If you perform the same actions with the HEIC picture, will preserve high quality. At the same time, information about editing is also stored. It means you can easily undo the changes you applied to the image. 

You’ve discovered what is a .HEIC file and seen that the new format is better than the JPEG one. Below, we will consider the main advantages and disadvantages of this container. 

Advantages:

  • Takes up double lesser the storage space. And one file can contain several images.

  • Despite the small size, the images are high-quality, even better than JPEG. The support of 16-bit color is a pleasant bonus. It will help you to edit your file more flexibly.

  • Except for the images themselves, the HEIC file extension contains valuable data about your photo, beginning with weight and width in pixels and ending with shooting time. Also, you see your edited images that you can take various actions with, for example, undo editing or make new changes. 

  • The container includes an alpha channel that allows for saving photos with transparency. 

  • Easily convert to JPEG, PNG, and other popular formats.

Disadvantages:

  • Only some browsers support HEIC on the Internet. 

  • Not quite compatible with other devices or applications. You may encounter that when you download the file to your computer, it will not open. In this case, you need to convert this container to another format supported by your computer. 

How did this Container Format Appear?

HEIC extension was first mentioned in 2013. The Moving Pictures Expert Group finalized the main standard of this format in 2015, a popular company that developed MP3 and MPEG. Understanding consumers’ need to save space in phone memory, Apple decided to adopt this option. And in 2017, it realized iOS 11, where HEIC was instead the valid JPEG format. Since then, it has been the primary one for storing multimedia files in modern iPhones and iPods. 

What is This Format for? 

Many wonders why are iPhone photos HEIC and this format is needed. Having high-quality and space-saving capabilities can open eyes to many things in personal and professional life. For example, you are a professional photographer who shoots many photos of aroma candles or natural cosmetics for Instagram. So, you require a lot of space for high-quality content on one device. HEIC allows realizing it. And if you like moving animations, you can change the stored sequence of images from HEIC to GIF with a converter.
