How to Change iPhone Camera from HEIC to JPG

To change your iPhone camera from HEIC to JPG, go to Settings > Camera > Formats on your iOS device and select Most Compatible.

By default, iPhones save photos using Apple's High Efficiency Image Format (HEIC) to conserve internal storage space. Choosing "Most Compatible" forces your iPhone camera to capture new photos as standard JPEGs, ensuring instant compatibility across Windows PCs, Android devices, and website upload forms.

Note that changing this setting only affects new photos you capture moving forward. All existing HEIC photos in your Photos library remain unchanged in HEIC format unless you convert them using a tool.

What Is HEIC on iPhone?

HEIC (High Efficiency Image Container) is Apple's default image format, introduced in iOS 11. It replaced the classic JPEG format across iPhones, iPads, and Mac computers.

Standard JPEG files save image data in a single flattened file. In contrast, HEIC acts as a flexible container that holds rich photo details while using modern file compression.

This container format allows your iPhone to bundle high-resolution pixel data, 16-bit color depth, and depth map data for Portrait mode into a compact file. It also supports Live Photo video clips within a single file wrapper.

For a complete breakdown of how the HEIF standard operates and its technical background, read our comprehensive guide on what HEIC format is. If you want a direct side-by-side technical evaluation of color and quality, read our in-depth technical comparison of HEIC vs JPG.

Why iPhones Use HEIC Instead of JPG

Apple selected HEIC as the default camera format primarily to solve storage constraints. Modern iPhone camera sensors capture massive amounts of image detail at 12 MP, 24 MP, and 48 MP resolutions. Storing those images as legacy JPEGs would quickly fill up device storage and iCloud backup quotas.

HEIC delivers modern compression algorithms that compress photographic image data roughly 50% more efficiently than JPEG without degrading visual fidelity. This allows you to store nearly twice as many photos on your iPhone without sacrificing image clarity.

How to Change iPhone Camera from HEIC to JPG

Follow these step-by-step instructions in iOS Settings to switch your iPhone camera format from High Efficiency (HEIC) to Most Compatible (JPG).

Open iPhone Settings

Unlock your iPhone or iPad and locate the gear-shaped Settings app icon on your Home Screen or App Library. Tap to open Settings.

Navigate to Camera Settings

Scroll down through the main Settings menu until you reach the system apps section. Tap Camera to open your camera configuration options.

Select Formats

At the very top of the Camera settings page, tap Formats. You will see two primary camera capture choices: High Efficiency and Most Compatible.

Tap "Most Compatible"

Tap Most Compatible so a checkmark appears next to it. Selecting Most Compatible instructs iOS to capture photos in standard JPEG/JPG format and record video using standard H.264 compression.

Capture a Test Photo

Exit Settings, open the Camera app, and take a new photo. Open the photo in the Photos app and swipe up to view file details. The file format will now show as JPEG instead of HEIC.

Important Notice: Existing HEIC Photos Are Not Converted

Changing your iPhone camera setting to Most Compatible only affects NEW photos captured after you select the option. All existing HEIC photos already saved in your Apple Photos library remain stored as .heic files.

To convert your existing library of HEIC photos to standard JPG images without changing camera settings or losing quality, use our free online HEIC to JPG converter. You can also read our step-by-step guides on how to convert HEIC to JPG on mobile and desktop and bulk converting HEIC to JPG in batches.

Keep HEIC but Automatically Transfer JPG to a Computer

What if you want to keep capturing photos in HEIC to save valuable iPhone storage, but need standard JPG files whenever you plug your iPhone into a Windows PC or Mac? Apple includes a built-in feature specifically for this best-of-both-worlds scenario.

You can configure iOS to automatically convert HEIC images into standard JPEGs whenever photos are transferred via Lightning or USB-C cable to a computer:

1Open Settings on your iPhone or iPad.
2Scroll down and tap Photos.
3Scroll to the very bottom of the page to locate the section labeled Transfer to Mac or PC.
4Select Automatic instead of Keep Originals.

With Automatic enabled, your photos remain stored as compact HEIC files on your iPhone and iCloud. However, when you connect your iPhone to a Windows computer via USB cable, iOS automatically converts the files on the fly into universally readable JPG images during copying.

If you have already copied raw .heic files directly to your Windows desktop or laptop and cannot open them, check our detailed tutorial on how to open HEIC files on Windows 10 and Windows 11.

Which Option Should You Choose?

Deciding between High Efficiency (HEIC) and Most Compatible (JPG) depends on how you use your iPhone and where you share your photos.

Choose High Efficiency (HEIC) If:

•You want to maximize iPhone internal storage and reduce iCloud backup size.
•You primarily share photos with other Apple users via AirDrop, iMessage, or Shared Albums.
•You want to record 4K video at 60 fps or 1080p slow-motion at 240 fps.
•You are comfortable using an online browser tool to convert HEIC to JPG whenever compatibility issues arise.

Choose Most Compatible (JPG) If:

•You frequently upload photos to job applications, school portals, or government forms that reject HEIC.
•You regularly transfer files to Windows PCs, Android phones, or legacy smart TVs.
•You work with older photo editing desktop applications that do not support HEIC extensions.
•You prefer complete zero-friction compatibility over saving iPhone disk space.

Frequently Asked Questions

Got questions about changing iPhone camera formats? Here are 10 clear answers to common questions.

Q1How do I change my iPhone camera format from HEIC to JPG?

Go to Settings > Camera > Formats on your iPhone. Tap "Most Compatible" instead of "High Efficiency". This instructs iOS to save all future camera captures as native JPG image files instead of HEIC.

Q2Does changing the iPhone camera setting to Most Compatible convert my existing HEIC photos to JPG?

No. Changing the camera setting in iOS Settings only applies to new photos captured after the setting is selected. Existing HEIC photos already saved in your Photos library remain in HEIC format unless you convert them using a tool like HEICJPGOnline.

Q3What is the difference between High Efficiency and Most Compatible on iPhone?

High Efficiency captures photos using the HEIF/HEIC format (and video in HEVC/H.265), which uses modern compression to reduce file sizes by roughly 50% while supporting 16-bit color depth. Most Compatible captures photos in standard JPEG/JPG format (and video in H.264), maximizing cross-platform compatibility across Windows, older Macs, Android devices, and web portals.

Q4Can I keep capturing photos in HEIC on iPhone but automatically send JPGs to my computer?

Yes. Go to Settings > Photos and scroll down to "Transfer to Mac or PC". Select "Automatic". When transferring photos via USB cable to a Windows PC or Mac, your iPhone will automatically convert HEIC files to standard JPG format during transfer.

Q5Why does Apple use HEIC as the default camera format instead of JPG?

Apple adopted HEIC as the default format in iOS 11 because it delivers high image quality at approximately half the storage footprint of a JPEG. This allows users to store up to twice as many photos on their iPhone while enjoying advanced features like Live Photos, depth maps, and higher color depth.

Q6Which setting should I choose: High Efficiency or Most Compatible?

Choose High Efficiency if saving storage space on your iPhone and iCloud is your top priority. Choose Most Compatible if you frequently share photos via web upload forms, transfer files to Windows PCs, or work with legacy photo editing software that does not support HEIC.

Q7Do JPG photos take up more storage space on iPhone than HEIC?

Yes. JPG photos typically take up about 1.5 to 2 times more storage space than equivalent HEIC photos captured with the same camera sensors and resolution on iPhone.

Q8Does shooting in JPG on iPhone reduce image quality compared to HEIC?

Both formats produce high-quality images, but HEIC supports 16-bit color depth and advanced compression algorithms. Standard JPG uses 8-bit color depth. For everyday photos, most people will not notice a visible difference between HEIC and JPG, though HEIC preserves more dynamic range data.

Q9How can I convert existing iPhone HEIC photos to JPG without changing my camera settings?

You can keep your camera set to High Efficiency to save device storage and convert individual or batch HEIC photos to JPG using a browser-based converter when compatibility is needed. The conversion processes your images client-side directly in your browser without requiring software installation or server uploads.

Q10Will changing my iPhone camera to JPG affect 4K video recording or Cinematic mode?

Selecting Most Compatible requires your iPhone to encode video in H.264 format. High-resolution or high-frame-rate video formats like 4K at 60 fps, 1080p at 240 fps, and 10-bit HDR recording require High Efficiency (HEVC) due to high bandwidth and processing hardware requirements.

Final Thoughts

Choosing between High Efficiency (HEIC) and Most Compatible (JPG) comes down to balancing storage space with universal accessibility. Capturing photos in HEIC allows you to store roughly twice as many high-resolution photos on your iPhone and iCloud storage while preserving rich color depth and Live Photo features.

On the other hand, setting your camera to Most Compatible guarantees that every photo you take opens seamlessly across Windows computers, Android smartphones, legacy editing applications, and web submission forms without conversion hurdles.

Remember that changing your camera format only applies to new photos captured after updating your settings. If you already have a library of HEIC images, you can leave your camera in High Efficiency mode and convert existing photos using our HEIC to JPG converter, HEIC to PNG, or HEIC to WebP tools. For entire photo libraries, follow our guide on bulk converting HEIC to JPG.
