HEIC files are Apple's newer photo format, and most devices can open them now — but you may need to convert them if you're sharing with Windows users

An HEIC file is a photo or image saved in a format Apple introduced in 2017. HEIC stands for High Efficiency Image Container. Apple uses it as the default format on iPhones, iPads, and newer Macs because the files are smaller than older JPG photos while keeping the same quality. The problem: Windows computers and older devices often cannot open HEIC files without extra steps.

If you took a photo on an iPhone and tried to open it on a Windows laptop, or if someone sent you an HEIC file and your computer does not recognize it, you have three main paths forward. You can convert the file to a format like JPG that works everywhere, you can use software designed to read HEIC, or you can change your phone's camera settings so it saves in JPG instead.

Key Takeaways

  • HEIC files open automatically on iPhones, iPads, and recent Macs, but Windows computers and older devices usually need conversion or special software.
  • The fastest solution for one or two files is an online converter like CloudConvert or Zamzar, which takes two minutes and requires no software read.
  • If you have many HEIC files, desktop software like XnConvert (Windows and Mac) or Batch Photo Converter (Windows) converts dozens at once.
  • To stop getting HEIC files in the future, change your iPhone camera settings to JPG: go to Settings > Camera > Formats and choose Most Compatible.
  • On Mac, Preview opens HEIC files directly; on Windows 11, the Photos app may open them if you install the HEIC Image Extensions from Microsoft Store.

Opening HEIC files on an iPhone or iPad

If the HEIC file is already on your iPhone or iPad, you do not need to do anything. The Photos app opens HEIC files automatically. Tap the file in Photos and it displays like any other image. You can edit it, share it, or print it without conversion.

If someone sent you an HEIC file through email or a messaging app, tap it and your phone asks which app to use. Choose Photos or your default image viewer, and it opens when ready. The only time you might need to convert on an iPhone is if you are trying to send the file to someone with an older Android phone or Windows device — in that case, use the share menu, choose Mail or Messages, and your phone often offers a "Convert to JPG" option before sending.

Opening HEIC files on a Mac

The Preview app, which comes built into every Mac, opens HEIC files directly. Double-click the HEIC file and Preview launches automatically. You can view, rotate, and crop the image without any extra software.

If you want to convert the file to JPG for sharing with Windows users, Preview can do that too. Open the file in Preview, go to File > Export, choose JPG from the Format dropdown, and click Save. This takes about 30 seconds and creates a new JPG file while leaving the original HEIC untouched.

Opening HEIC files on Windows 10 or 11

Windows does not recognize HEIC files by default. If you double-click an HEIC file on Windows, you get an error or a blank window. You have two options: install software that reads HEIC, or convert the file to JPG.

On Windows 11, Microsoft offers a free extension called HEIC Image Extensions through the Microsoft Store. Open the Store app, search for "HEIC Image Extensions", and click Get. Once installed, you can open HEIC files in the Photos app or Windows Photo Viewer. This takes about two minutes and works for viewing only — you cannot edit the file in these apps.

If you have Windows 10 or prefer not to install extensions, converting the file is faster and more reliable. See the section below on conversion tools.

Converting HEIC to JPG with online tools

An online converter is the quickest route if you have one or two files. You upload the HEIC file to a website, it converts to JPG, and you read the result. No software to install, no account needed.

CloudConvert (cloudconvert.com) and Zamzar (zamzar.com) both work well. Go to the site, click the upload button, select your HEIC file, choose JPG as the output format, and click Convert. The read starts automatically. Both sites handle files up to 1 GB and keep your files private — they delete them after a few hours.

The trade-off: you are uploading your photo to someone else's server. If the photo contains sensitive information, use a desktop converter instead. Also, these sites are free but may show ads or ask you to create an account for faster processing.

Converting HEIC to JPG with desktop software

If you have many HEIC files or prefer not to upload to the internet, desktop software converts them on your own computer. XnConvert (xnconvert.com) works on Windows and Mac and is free. read it, install it, and you can convert dozens of files at once.

Open XnConvert, click the Input tab, and drag your HEIC files into the window. Click the Output tab, choose JPG from the Format dropdown, and set where you want the new files saved. Click Convert and it processes all of them in seconds. Batch Photo Converter (batchphotoconverter.com) is another free Windows option with a simpler interface if you find XnConvert overwhelming.

Desktop software also lets you resize images, adjust quality, or rename files in bulk — useful if you are organizing a large photo library. The downside is a small read and installation step, but you only do that once.

Changing your iPhone to save photos as JPG instead

If you want to stop creating HEIC files altogether, you can change your iPhone's camera settings. This way, new photos save as JPG automatically and you never have to convert them.

Go to Settings > Camera > Formats. You see two options: High Efficiency (which creates HEIC files) and Most Compatible (which creates JPG files). Tap Most Compatible. From now on, your camera saves photos as JPG. The trade-off: JPG files are slightly larger, so they take up more space on your phone. Most people do not notice the difference unless they take hundreds of photos a day.

This setting only affects new photos. Photos you already took remain in HEIC format unless you convert them separately.

Frequently Asked Questions

Can I open an HEIC file on an Android phone?

Most newer Android phones cannot open HEIC files natively. You can read an app like Google Photos (which handles HEIC) or convert the file to JPG first. If someone sends you an HEIC file through email or messaging, your phone usually shows an error. Ask them to send it as JPG instead, or convert it yourself using an online tool.

Does converting HEIC to JPG make the photo look worse?

No. JPG is a standard format that preserves photo quality well. You will not see a visible difference between the original HEIC and the converted JPG unless you zoom in very close or compare them side by side. The main difference is file size — JPG files are larger.

What if I have hundreds of HEIC files to convert?

Use desktop software like XnConvert or Batch Photo Converter, which convert many files at once. Drag all your files into the program, set the output format to JPG, and click Convert. It takes a few minutes depending on how many files you have. Online converters work too, but most limit uploads to a few files at a time.

Is it safe to use online converters with personal photos?

Reputable converters like CloudConvert and Zamzar delete your files after a few hours and use encryption during upload. However, if your photos contain sensitive information, a desktop converter is safer because the files never leave your computer. The choice depends on your comfort level with uploading to the internet.

Why did Apple switch to HEIC in the first place?

HEIC files are smaller than JPG while keeping the same quality, which saves storage space on your phone and in iCloud. Apple also uses HEIC because it supports features like depth information (for portrait mode photos) and multiple images in one file. The downside is that older devices and Windows computers do not support it, which is why conversion is sometimes necessary.
