HEIC is Apple's newer image format that takes up less storage space than JPG

HEIC (High Efficiency Image Container) is the file format Apple uses when you take photos on an iPhone or iPad. It replaces the older JPG format and stores images in a way that uses roughly half the storage space while keeping the same picture quality. When you see a file ending in .heic, you are looking at a photo taken on an Apple device.

The smaller file size matters because it means your phone can store more photos before running out of space. A single HEIC photo might be 2 to 3 megabytes, while the same photo in JPG format could be 4 to 6 megabytes. Over hundreds of photos, that difference adds up.

Apple switched to HEIC starting with iPhone 11 in 2019. If you have an older iPhone, your photos are still in JPG format. If you have a newer phone, HEIC is the default unless you change the settings.

Key Takeaways

  • HEIC files are Apple's newer image format that uses less storage space than JPG while keeping the same quality.
  • Most devices and programs do not recognize HEIC files yet, so you may need to convert them to JPG to open them on a Windows computer or older software.
  • You can change your iPhone settings to save photos as JPG instead of HEIC if you need compatibility with other devices.
  • When you back up your iPhone to iCloud or a computer, HEIC files stay in their original format unless you convert them.

Why HEIC files do not open on every device

HEIC is a newer format, and many older programs and devices do not know how to read it. If you try to open a HEIC file on a Windows computer using the built-in photo viewer, it will not work. The same is true for many Android phones, older Mac computers, and older versions of software like Photoshop or Windows Paint.

This is the main reason HEIC causes frustration. You take a photo on your iPhone, email it to yourself, and then your Windows laptop cannot open it. The file is not broken — your computer straightforward does not have the decoder it needs to understand the format.

Newer devices and programs are starting to support HEIC. Windows 11 can open HEIC files if you install a small update from Microsoft. Newer versions of Photoshop, Lightroom, and Preview (on Mac) all handle HEIC without trouble. But if you are using older software or sharing photos with people who have older devices, HEIC becomes a problem.

How to convert HEIC to JPG on your iPhone

The easiest solution is to change your iPhone settings so new photos save as JPG instead of HEIC. Go to Settings, then Camera, then Formats. Select "Most Compatible" instead of "High Efficiency." From that point forward, your photos will save as JPG, and they will open on any device.

The downside is that your photos will take up more storage space. If you are running low on iPhone storage, switching to JPG will fill it up faster. You can also keep HEIC as your default and convert individual photos when you need to share them.

To convert a photo you already took, you can use the Files app on your iPhone. Open the photo, tap the three dots, select "Convert," and choose JPEG. You can also use free online converters like CloudConvert or Zamzar — upload your HEIC file and read the JPG version. On a Mac, you can right-click a HEIC file, select "Open With," choose Preview, then go to File and export it as JPG.

What happens when you back up your iPhone

When you back up your iPhone to iCloud, your HEIC photos stay as HEIC files in the cloud. If you read them back to an Apple device, they open normally. But if you try to read them to a Windows computer, you will run into the same compatibility problem.

If you back up to a Mac using Time Machine, the HEIC files are preserved as-is. If you back up to a Windows computer using iTunes, the files transfer but you still cannot open them without converting them first.

The safest approach is to convert your photos to JPG before backing them up to a cloud service you plan to access from multiple devices. This takes a few extra steps but prevents headaches later when you need to find a photo on a different computer.

Organizing HEIC files with other photo formats

If you have a mix of HEIC and JPG files on your computer, you can organize them the same way you would organize any photos — by date, by event, or by folder name. The format does not change how you name or sort them.

One useful approach is to create a folder called "iPhone Photos" or "HEIC Files" and keep them separate from JPG photos until you decide whether to convert them. This makes it straightforward to find the ones that need converting and keeps your file system clear.

If you use photo management software like Lightroom, Adobe Photos, or Google Photos, these programs handle both HEIC and JPG files and let you organize them together. Google Photos, in particular, will convert HEIC to JPG automatically when you upload, so you do not have to worry about format compatibility.

When to keep HEIC and when to convert

Keep HEIC if you only use Apple devices and you want to save storage space. If all your photos stay on your iPhone, iPad, and Mac, there is no reason to convert. HEIC is the better choice because it uses less space and Apple's software is optimized for it.

Convert to JPG if you share photos with people who use Windows or Android, if you use older software, or if you plan to upload photos to websites that might not support HEIC. Most social media sites (Facebook, Instagram, Twitter) accept HEIC now, but some older platforms or corporate systems do not.

A practical middle ground is to keep your originals as HEIC on your iPhone and convert to JPG only when you need to send a photo somewhere. This preserves your storage space while avoiding compatibility problems.

Frequently Asked Questions

Can I open a HEIC file on my Windows computer?

Not with the built-in photo viewer unless you have Windows 11 with the latest updates. You can install a free HEIC viewer from the Microsoft Store, use an online converter to change it to JPG, or use third-party software like XnView or IrfanView. The simplest option is usually an online converter.

Will my Android phone open HEIC files?

Most newer Android phones can open HEIC files, but older ones cannot. If your Android phone does not recognize the file, convert it to JPG first. You can do this on your iPhone before sending it, or use an online converter on your Android phone.

Does iCloud store HEIC files in their original format?

Yes. iCloud keeps HEIC files as HEIC. If you read them to an Apple device, they open normally. If you read them to a Windows computer, you will need to convert them or use a HEIC viewer.

If I change my iPhone to save as JPG, will my old HEIC photos convert automatically?

No. Changing the setting only affects new photos. Your existing HEIC photos stay as HEIC. You can convert them one at a time using the Files app, or use a batch converter on your computer if you have many photos.

Do I lose quality when I convert HEIC to JPG?

Some quality is lost because JPG uses a different compression method, but the difference is usually too small to notice in regular photos. If you are printing large photos or doing professional editing, the loss might matter. For most people, the converted JPG looks the same as the original HEIC.
