While taking photos and uploading them places, like this blog, I get the photos in .heic format from the iPhone, then need to convert them into JPEG for WordPress. There are a few paid, and some questionable freeware out there to do it, but I wanted to use open source tools. ImageMagick is an open source tool that can do the conversion, but that requires the command line, so I found the registry keys needed to add a right click context menu to convert the images!

This context menu only shows up when selecting a .heic file as well, which is a nice way to do it. How to install:

• Install ImageMagick (link), the version I got was “ImageMagick-7.0.11-4-Q16-HDRI-x64-dll.exe”
• Copy the following lines into a text document

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SystemFileAssociations\.heic\Shell\convertojpeg]
@="Convert To JPEG"

[HKEY_CLASSES_ROOT\SystemFileAssociations\.heic\Shell\convertojpeg\command]
@="\"C:\\Windows\\System32\\cmd.exe\" /C magick.exe mogrify -verbose -format jpg \"%1\""

• Name it install_imagemagick.reg (or really anything.reg)
• Open that file in file explorer

After install you should be able to right click a .heic photo and “Convert To JPEG”. I did not need to restart/logout/restart explorer. I am calling cmd.exe first instead of the program directly, because this allows you to easily update ImageMagick and not need to directly link to the file.
