Do you know those endless iOS updates that seem to change generally nothing much except take up more space in your iPhone? Well, one of the subtle changes they did make is the way photo files are stored on your phone.

After updating your iPhone to iOS 11 or later, the majority of us will find that photos taken on the iPhone are saved in the HEIC format instead of the standard JPG format.

What is a HEIC File?

HEIC stands for High Efficiency Image Coding, which is Apple’s version of the HEIF image format. The reason why Apple started to use this new file format is that it has a high-compression rate while retaining the original quality of the images.

Basically, when a JPEG image takes 4 MB of your phone’s memory, a HEIC image will only take about half of that. That will save a load of memory space on your Apple devices.

Another feature of HEIC is that it also supports 16-bit deep color images, which is a game-changer for iPhone photographers.

It means that any sunset photos taken now will retain their original vividness, unlike the old JPEG format which reduces the quality of the image due to the 8-bit capacity.

However, a downside of this new photo format is that many programs, along with any Windows operating system, does not support this file format yet.

What is a JPG File?

JPG (or JPEG) is one of the original standardized image formats. It’s commonly used as a method for image compression, especially for digital photography. Because this file format is compatible with almost every device, converting your images to JPG would mean that you can use your photographs with any software as you typically do.

The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. However, sometimes your image quality and file size might be compromised, making it a hassle for graphic designers and artists.

That’s it. You may define the output Quality as well as preview the file size in the same window.

Method 2: Use an Online Conversion Tool

Final Words

While it’s kind of surprising for us to get to know this new image format — HEIC after Apple “quietly” changed the default image format in the iOS 12 update, users don’t have many choices over the image types we want to save as. A HEIC file has its pros but its cons are also a bit annoying, especially if you have the need to deal with iPhone photos on a Mac machine.

Luckily, there are several ways to convert HEIC to JPG depending on how many photos you want to convert at one time. Preview is a built-in app that allows you to convert several images in seconds, online conversion tools are handy to use, and iMazing is also a nice choice if you want to convert a batch of files.
