How to Batch Convert HEIC Photos from iPhone to JPG

Why Does Your iPhone Save Photos as HEIC?

Ever since iOS 11, Apple has used HEIC (High Efficiency Image Container) as the default photo format on iPhones and iPads. Apple made this decision for one primary reason: storage efficiency. HEIC files are roughly half the size of equivalent JPEG images while maintaining the same visual quality. For a device that stores thousands of photos, this means you can fit nearly twice as many pictures in the same amount of storage space.

HEIC also supports advanced features that JPEG cannot match, including 16-bit color depth, transparency, and the ability to store multiple images in a single file (which is how Live Photos work). From a purely technical standpoint, HEIC is a superior format to JPEG in almost every measurable way.

But there is one enormous catch.

The Compatibility Frustration

Despite being technically superior, HEIC has a serious compatibility problem that frustrates millions of users every single day. If you have ever tried to share an iPhone photo with someone using a Windows PC or an Android phone, you have probably encountered this firsthand.

Here is what typically happens: you take a beautiful photo on your iPhone, text it to a friend with an Android phone, and they receive a file they cannot open. Or you transfer vacation photos to your Windows laptop, and Windows tells you it needs to install a special codec just to view them. Or you try to upload a photo to a website, and the upload form rejects your .heic file entirely.

The core issue is that HEIC relies on the HEVC (H.265) codec, which is patented and requires licensing. This has slowed adoption outside of Apple's ecosystem. Windows requires a separate codec installation, many Android devices have limited or no HEIC support, most web browsers cannot display HEIC images (only Safari on macOS can), and many websites and web applications do not accept HEIC uploads.

When you need to share photos with people outside the Apple ecosystem, or upload them to websites and services that do not support HEIC, converting to JPG is the simplest and most reliable solution.

Method 1: Use PhotoFormatLab's Batch Converter

The fastest and most private way to batch convert HEIC photos to JPG is using PhotoFormatLab's batch converter. This browser-based tool processes all your files locally on your device, meaning your photos never get uploaded to any server.

Here is how to batch convert your HEIC photos step by step:

Why this is the best method for batch conversion:

This method is especially ideal when you have a large batch of photos from a vacation, event, or photo shoot that you need to share with Windows or Android users.

Method 2: Change Your iPhone Camera Settings

If you want to prevent the HEIC problem entirely for future photos, you can change your iPhone's camera settings to save photos as JPEG instead of HEIC. This is a permanent solution that ensures every new photo you take will be in a universally compatible format.

Here is how to make the change:

Once you select "Most Compatible," your iPhone will save all new photos as JPEG files and all new videos as H.264 instead of HEVC. These formats are supported by virtually every device and application in existence.

The trade-off to be aware of: JPEG files are roughly 1.5 to 2 times larger than equivalent HEIC files. If you take a lot of photos, this will consume more storage space on your iPhone. For example, if you typically take 500 photos per month and each HEIC file averages 2 MB, switching to JPEG means those same photos will average 3.5 to 4 MB each, using an extra 750 MB to 1 GB of storage per month.

Important: This setting only affects new photos taken after you make the change. Your existing HEIC photos will remain in HEIC format and will still need to be converted using Method 1 if you want them in JPG.

Method 3: AirDrop and Email Auto-Conversion

Apple has built automatic format conversion into some of its sharing features. When you share photos through certain channels, iOS can automatically convert HEIC to JPEG behind the scenes.

AirDrop: When you AirDrop photos from your iPhone to a Mac, the photos are transferred in their original HEIC format by default. However, if you AirDrop to a device that does not support HEIC, iOS may automatically convert them to JPEG. This behavior is not always consistent and depends on the receiving device's capabilities.

Email: When you attach photos to an email using the default Mail app, iOS typically converts HEIC images to JPEG automatically. This makes emailed photos compatible with virtually any device or email client the recipient uses.

Limitations of this method:

For occasional sharing of a few photos, this method works reasonably well. For batch converting dozens or hundreds of photos, Method 1 (PhotoFormatLab) is far more efficient and reliable.

Tips for Handling Hundreds of Photos

When you have a large collection of HEIC photos to convert, a few strategies can make the process smoother:

Frequently Asked Questions

Does converting HEIC to JPG reduce the quality of my photos?

There is a small amount of quality loss because both HEIC and JPG use lossy compression, and converting between lossy formats introduces a second round of compression. However, at a quality setting of 90% or above, the difference is virtually imperceptible to the human eye. For all practical purposes, your converted JPG photos will look identical to the HEIC originals.

Can I convert HEIC to formats other than JPG?

Yes. PhotoFormatLab supports conversion from HEIC to many formats, including PNG for lossless quality, WebP for web-optimized images, and others. PNG is a good choice if you need perfectly lossless output, while WebP is ideal for website images.

How long does it take to batch convert hundreds of HEIC photos?

Processing time depends on your device's hardware and the number and resolution of the photos. On a modern computer with a recent browser, converting 100 standard iPhone photos typically takes under a minute. Since PhotoFormatLab processes files locally in your browser, there is no upload or download wait time for the conversion itself.

Will my photo metadata (date, location, camera settings) be preserved?

PhotoFormatLab preserves basic EXIF metadata during conversion, including the date the photo was taken and camera settings. GPS location data and other detailed metadata can also be preserved depending on the output format and settings you choose.
