HEIC is a remarkable format, delivering image quality comparable to JPG at half the file size. However, even years after Apple introduced it on iPhone, cross-platform compatibility remains inconsistent.
This is why many users need to switch to JPG. Apple's iOS auto-converts HEIC to JPG when sharing to non-compatible apps like Mail or Notes, or transferring to other devices—but issues persist.
For instance, as someone who relies on Google Photos for backups (which supports HEIC but doesn't allow JPG re-downloads), I've often had to convert files manually on my PC. Fortunately, changing your iPhone's default camera format to JPG is straightforward.
Fun fact: HEIC stands for High Efficiency Image Coding, also known as HEIF (High Efficiency Image Format).To change your camera's capture format, open the Settings app, scroll to Camera, and tap Formats. Under Camera Capture, select Most Compatible for JPG photos and H.264 videos (instead of HEIC/HEVC).
Step 1: Open Settings > Camera > Formats.
Step 2: Tap Most Compatible.
Your iPhone will now capture JPG photos and H.264 MOV videos. You can toggle this anytime in Settings.
Here's what to know before switching:
New settings only affect future captures. To convert existing library: Enable automatic transfer (Settings > Photos > Transfer to Mac or PC > Automatic) or use App Store converters.
JPG/H.264 files use about twice the space of HEIC/HEVC. Check video sizes in Settings > Camera > Record Video.
With iCloud Photos enabled, backups grow faster beyond the free 5GB. Consider Google Photos for unlimited storage or other alternatives.
Most Compatible limits 4K/60fps and 1080p/240fps slo-mo to save space with H.264.
JPG may appear sharper due to less compression, but HEIC offers wider color gamut and depth data—ideal for editing on advanced displays.
Compatibility justifies the change, but HEIC saves space and is more advanced. If staying in Apple's ecosystem, stick with it.
