Launched alongside iOS 11 and designed to save as much storage space as possible on your iOS device, Apple's HEIC and HEIF (short for High-Efficiency Image File Format) still has a long way to go until it becomes a widely-supported format.

Obviously, HEIC is fairly well supported on most of Cupertino's newer devices but no so much on other devices out there, which could be especially troublesome for most Windows users.

That said, you can convert your HEIC files to other, more widely-supported formats with the help of various online converters or you could try a local solution in the form of a useful app called HEIC to JPG Converter.

This tool is capable of much more than its name suggests, as not only does it allow you to convert your HEIC files to JPG, but also to other types of formats such as GIF, BMP, PNG, PCX, TIF, and TGA.

It's also worth pointing out that it comes with support for batch conversion and batch renaming operations, as well as for drag and drop gestures. Gladly, the utility is capable of resizing, rotating, flipping and mirroring the resulting images as well.

In addition, you're provided with the possibility of adding various effects (such as Greyscale and Auto-balance), and both custom image and text watermarks as well. Head over to the app's Options section, and you can tweak various interesting aspects such as the TIFF and GIF compression algorithms and some JPEG conversion-related ones.

Taking everything into account, HEIC to JPG Converter is without a doubt a very useful app, especially considering that HEIC is still pretty much a novelty (one-two months after iOS 11's release, at the time of writing).
