Since iOS 11 Apple has made HEIC the default file format for saving photos on iPhone and iPad. The move away from JPG is to reduce file sizes and for its other benefits including the ability to have multiple photos (from a burst sequence, say) in one file.

Android 9 (Pie) also added support for this high-efficiency format, and it can be worth using it if your phone doesn't already save photos in this modern format.

The problem is that your laptop or PC probably can't open these HEIC files after you've imported them from your phone. Microsoft added HEIC (and HEIF) support in version 1809 (the October 2018 update), but you may still have to jump through a couple of hoops before the native Photos app will open these files and let you view them.

What is an HEIC file?

If you copy photos from a recent iPhone or iPad to a PC or laptop, chances are you’ll see a lot of strange HEIC files:

The format was developed by MPEG – not Apple - so it's not Apple trying to do its own proprietary thing. In fact, HEIC is slowly usurping the established (but old and flawed) JPG format.

Images with a .heic are compressed using HEVC, which is the high-efficiency video codec. These images are then stored in a HEIF file, which stands for High Efficiency File Format

There are lots of benefits of using HEIF files, even if it is a bit confusing that the file is called HEIC rather than HEIF.

Here’s why HEIC files are great:

  • Around half the size of JPG for the same quality
  • Can store multiple photos in one file (ideal for Live Photos and bursts)
  • Supports transparency like GIF files
  • Can store image edits, such as cropping and rotating so you can undo them
  • Support 16-bit colour vs JPG’s 8-bit

How do I open an HEIC file in Windows 10?

Make sure you have Windows 10 version 1809 or later. (If you're not sure, type winver into the search box at the bottom-left of the Windows 10 desktop, then press Enter.) If the version is below 1809, then open the Settings app and go to Update & Security > Windows Update.

Next, you need to install the HEIF support.

Now, click the following link to get the HEVC Video Extensions. You'll notice that if you search the store for these, you'll be charged 79p / $0.99, but the link we've provided lets you get the 'from Device Manufacturer' version which is identical, and free.

In both cases, click the Get button and wait for the software to be installed.

Now, you should find that double-clicking on an .heic file will open it in the default Windows 10 Photos app. If not, you should see a window similar to the one below where you can click on the Photos app and tick the box marked: Always use this app to open .HEIC files.

How to convert HEIC to JPG

When you open a file it will behave as a normal JPG. You can edit it as normal using the tools available in the Photos app, but you'll also notice that even if you don't make any changes after clicking on the 'Edit & Create' button at the top right, there's a blue 'Save a copy' button at the bottom which lets you re-save the photo in your preferred format, including JPG.

That method is fine if you want to convert the occasional photo, but there are far easier ways of batch converting a lot of photos to JPG

There are quite a few free apps including iMazing HEIC Converter and Apowersoft's HEIC to JPG converter, plus online converters such as HEIC to JPG.

If you want more control, such as the level of JPG compression, file renaming and more, then check out Duckhead's HEIC to JPG - The HEIC Image Converter on the Microsoft Store.

Here, we're using iMazing converter, a small app which lets you drag and drop files and choose whether to convert them to JPG or PNG, as well as the output folder.

Share as JPG from your iPhone

If you'd rather avoid converting files in Windows, then as long as you still have the photos on your iPhone or iPad, you can select and share them in the Photos app via email or upload to a cloud storage service.

When you do this they’ll be converted to JPEGs automatically. When you choose to share via Mail you'll get to choose which size - always go for the original (maximum) file size if you want to retain the best quality.

And if you choose a cloud provider such as Google drive, you should see that the files will be saved with a .jpeg extension.
