The iPhone offers one of the best camera systems on any smartphone, but users might face compatibility issues when taking photos, as the iPhone defaults to unique HEIF and HEVC formats. The popular Apple smartphone has seen immense changes since its release in 2007, and the camera system is no exception. The first iPhone didn't even have the ability to take videos, and was limited to a tiny sensor that could capture only images. Over the years, cameras on the iPhone have improved immensely, with most models now sporting multiple cameras.
The recent upgrades to iPhone cameras have produced better photos, which in turn, create larger files. Apple's 'Pro' lineup of iPhones feature ProRAW photos that can be shot on the iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13 Pro, or iPhone 13 Pro Max running iOS 14.3 or later. ProRAW photos preserve more detail in a photo, which is essential in post-production editing. However, they come at a cost — ProRAW photos are nearly 25MB in size on average, which is roughly 10 times the size of a typical photo. Despite providing higher quality photos, Apple has come up with new ways to keep file sizes to a minimum, including the creation of a niche file format of its own.

Typically, HEIF files are significantly smaller than more common file formats, like JPG and JPEGs. Though there is a benefit to having smaller files on a device — HEIF files are 1.3MB on average, while JPEGs average 2.5MB per photo — there are some downsides. Apple claims that the HEIF format preserves all of the detail and clarity of typical file formats without the excess
