HEIC files are Apple's newer photo format, and most devices outside the Apple ecosystem won't open them without help

HEIC stands for High Efficiency Image Container. Apple switched to it as the default format for iPhone photos around 2017 because it compresses photos to smaller file sizes while keeping the same quality as older JPEG files. The problem: Windows computers, Android phones, and many older programs don't recognize HEIC by default. You have three practical routes — convert the file to JPEG before opening it, use software that reads HEIC natively, or change your iPhone settings to stop creating HEIC files in the first place.

Which route makes sense depends on whether you're dealing with one photo or hundreds, and whether you want to keep using HEIC on your iPhone going forward.

Key Takeaways

  • Windows 10 and 11 can open HEIC files if you install the HEIF Image Extensions app from the Microsoft Store, which is free.
  • Mac computers open HEIC files automatically in Preview and Photos, with no extra software needed.
  • Android phones cannot open HEIC files natively; you need a third-party app like Google Photos or Heic to JPEG converter apps.
  • Converting HEIC to JPEG before sharing removes the format problem entirely and works on any device.
  • Turning off HEIC on your iPhone (Settings > Camera > Formats > Most Compatible) makes your phone save new photos as JPEG instead.

Opening HEIC files on Windows

Windows 10 and 11 do not open HEIC files by default, but Microsoft provides a free app called HEIF Image Extensions that adds the ability. Open the Microsoft Store on your Windows computer, search for "HEIF Image Extensions," and install it. Once installed, you can double-click any HEIC file and it will open in the Photos app.

If you don't want to install the extension, you can convert the file instead. Online converters like CloudConvert or Zamzar let you upload an HEIC file and download it as JPEG. This works from any browser and requires no software installation, though it does mean uploading your photo to someone else's server.

Opening HEIC files on Mac

Mac computers have supported HEIC since macOS High Sierra (2017). Double-click any HEIC file and it opens in Preview automatically. You can also open HEIC files in the Photos app, which is where most Mac users manage their photo library anyway.

If you need to convert HEIC to JPEG on a Mac, Preview can do that too. Open the file in Preview, click File > Export, choose JPEG from the Format dropdown, and save. No extra software needed.

Opening HEIC files on Android

Android phones do not have built-in HEIC support. If someone sends you an HEIC file and you try to open it, most Android phones will show an error or refuse to open it at all.

Your options are limited. Google Photos can display HEIC files if you upload them to your Google Photos library, but that requires internet and cloud storage. For a local solution, search your phone's app store for "HEIC viewer" or "HEIC to JPEG converter" — apps like Heic Converter or Image Converter exist, though quality and reliability vary. The most reliable approach is to ask whoever sent you the file to convert it to JPEG first, or to convert it yourself on a computer before transferring it to your phone.

Converting HEIC to JPEG on an iPhone

If you have an iPhone and want to convert existing HEIC photos to JPEG, you'll need a computer. Connect your iPhone to a Mac or Windows computer, open the file manager (Finder on Mac, File Explorer on Windows), and locate your photos. On Mac, you can convert them in Preview as described above. On Windows, convert them using the online method or third-party software.

For new photos going forward, you can change your iPhone's default format. Open Settings > Camera > Formats and select "Most Compatible" instead of "High Efficiency." This tells your iPhone to save new photos as JPEG. The change applies only to photos taken after you make it — existing HEIC photos stay as HEIC.

When to convert versus when to keep HEIC

HEIC files are genuinely smaller and higher quality than JPEG, so there's a real benefit to keeping them if everyone you share photos with can open them. If you're storing photos on your own computer and never sharing them, HEIC is fine. If you regularly send photos to people with Android phones, older computers, or older software, converting to JPEG removes friction.

A practical middle ground: keep HEIC files as your archive on your computer, but convert to JPEG before emailing or messaging photos to others. This gives you the storage benefit without the compatibility headache.

Frequently Asked Questions

Can I open HEIC files in Photoshop or other editing software?

Photoshop CC (2019 and later) opens HEIC files on both Mac and Windows. Older versions do not. If you're using an older version, convert to JPEG first. Many free editors like GIMP do not support HEIC, so check your software's documentation before assuming it will work.

Why does my iPhone create HEIC files instead of JPEG?

Apple chose HEIC as the default because it saves storage space — HEIC files are typically 30 to 50 percent smaller than JPEG at the same quality. This matters on phones with limited storage. If the smaller file size doesn't benefit you and the format causes problems, switching to "Most Compatible" mode stops the issue.

If I convert HEIC to JPEG, will the photo quality get worse?

No. HEIC and JPEG are both compressed formats, but converting from one to the other does not add a second layer of compression. The photo will look the same as the original HEIC file. You're not losing quality by converting.

Do I need to convert HEIC files before uploading to social media?

Most social media platforms (Facebook, Instagram, Twitter, TikTok) accept HEIC files and convert them automatically on their servers. You can upload HEIC directly. If a platform rejects the file, convert to JPEG and try again — but this is rare.
