Does your iPhone save photos in HEIC even though you'd prefer plain JPEG? You're not alone. Many iPhone users want to switch from HEIC to JPEG for better compatibility with non-Apple devices, Windows PCs, and online services.

This guide shows you exactly how to turn off HEIC on your iPhone and switch to JPEG (labeled as Most Compatible in iOS). We'll cover iOS 18, iOS 17, and older versions.

Why Switch from HEIC to JPEG on iPhone?

HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. While it offers better compression — files are roughly half the size of equivalent JPEGs — it comes with trade-offs:

| Factor | HEIC (High Efficiency) | JPEG (Most Compatible) |

|--------|----------------------|----------------------|

| File size | ~2 MB per photo | ~4 MB per photo |

| Quality | Excellent (HEVC-based) | Excellent (less efficient compression) |

| Windows compatibility | Requires codec or conversion | Native support everywhere |

| Email attachments | May not open on recipient's device | Opens on any device |

| Social media | Some platforms recompress poorly | Universally accepted |

| Photo printing kiosks | Often unsupported | Widely supported |

If you frequently share photos with friends and family who don't use Apple devices, or if you need to upload images to websites, web apps, or print services, switching to JPEG saves you the hassle of manual conversion every time.

How to Disable HEIC on iPhone (iOS 18 & 17)

The setting is called High Efficiency (HEIC) vs Most Compatible (JPEG). Here's how to change it:

Step 1: Open Settings

Tap the Settings app on your iPhone home screen.

Step 2: Go to Camera Settings

Scroll down and tap Camera > Formats.

Step 3: Select Most Compatible

Under Camera Capture, you'll see two options:

• High Efficiency — saves photos as HEIC and videos as HEVC (H.265)
• Most Compatible — saves photos as JPEG and videos as H.264

Tap Most Compatible.

✅ That's it! New photos you take will now be saved as JPEG instead of HEIC.

For iPhone Users Running iOS 16 or Older

The steps are nearly identical:

• Open Settings
• Tap Camera > Formats
• Select Most Compatible (instead of High Efficiency)

The option has been in the same location since iOS 11 introduced HEIC support.

What About Photos You Already Took in HEIC?

Changing the setting only affects new photos. Your existing HEIC photos remain in HEIC format — they don't get retroactively converted.

To convert existing HEIC photos to JPEG, you have several options:

Option A: Convert with HEICFLY (Free, No Upload)

Visit heicfly.waaplink.com — drag and drop your HEIC files, and they're converted to JPEG instantly. Everything happens in your browser (no upload, no privacy risk).

Option B: Export from iPhone

• Open the Photos app
• Select the HEIC photos
• Tap the Share button
• Choose Export > Export Unmodified Original... or use a shortcut

Note that iOS sometimes exports as HEIC even when sharing. For reliable JPEG output, use a dedicated converter.

Option C: Use the "Automatic" Transfer Setting

When connecting your iPhone to a Windows PC or Mac:

• Go to Settings > Photos
• Scroll down to Transfer to Mac or PC
• Select Automatic — iOS automatically converts HEIC to JPEG during transfer

When Should You Keep HEIC?

HEIC isn't all bad. Consider keeping High Efficiency if:

• You're fully in the Apple ecosystem (iPhone, Mac, iCloud)
• You want to save storage space on your device
• You value the smaller file sizes for iCloud backups
• You use apps that fully support HEIC (Photos, Lightroom, Pixelmator)

The 50% smaller file size means you can store roughly twice as many photos in the same iCloud storage tier.

Pro Tips for Managing iPhone Photo Formats

• Keep HEIC for everyday iPhone use, switch to JPEG only when sharing. Use the Share sheet's format options.
• Use a Shortcut: Create an iOS Shortcut that converts HEIC to JPEG when you export photos to specific apps.
• Batch convert: When you need to convert many HEIC photos at once, use heicfly.waaplink.com for unlimited free conversions.
• Check before sending: If your recipient says "I can't open this photo," it's likely HEIC. Resend as JPEG.

Frequently Asked Questions

Will switching to JPEG reduce my photo quality?

No — JPEG at the same resolution retains excellent quality. The difference is mostly in file size efficiency, not visible image quality.

Does Most Compatible affect Live Photos?

Yes. In Most Compatible mode, Live Photos are saved as separate JPEG and MOV files instead of the combined HEIC+HEVC package. Functionality remains the same.

Can I have both formats at the same time?

iOS doesn't support shooting in both formats simultaneously. However, you can set your iPhone to High Efficiency for storage and convert specific photos to JPEG using HEICFLY when needed.

Will this affect my iCloud photos?

Photos already in iCloud remain in their original format. New photos taken after switching will be JPEG. iCloud works fine with both formats.

Conclusion

Switching your iPhone from HEIC to JPEG is a one-minute settings change that eliminates compatibility headaches forever. Open Settings > Camera > Formats and choose Most Compatible to start saving photos as JPEG.
