How to convert a HEIF/HEIC image to JPEG in El Capitan?
Bravo! MacX MediaTrans successfully converts HEIC to JPG within several clicks. And I find it's more than a HEIC encoder. It organized photos well by categories from the latest to the oldest. And as I encoded HEIC to JPEG, it encodes and transfers photos to Mac simultaneously, without changing the image format on iOS 11 iPhone. Better yet, the whole process is done in a blink of an eye, merely 2 or 3 secs for over 30 HEIC photos encoding.

To be frank, I'm quite disappointed at TunesGo on MacOS. It claims that it could encode HEIC to JPG after transferring HEIC photos from iPhone to Mac. But as I tried, the exported photos are still in .heic format. After I changed the file suffix from .heic to .jpg manually, it can be open, but in thumbnails, rather than a real 4K resolution image. I don't know it's a matter of wrong use or the HEIF encoder itself.
AnyTrans undoubtedly is a decent HEIF/HEIC converter that does help me encode HEIC to JPEG format for limitless viewing on Mac, Windows, Android devices. But I still rated it with 3.5 stars because it took me a lot of time to find my target HEIC photos after my iPhone data was synced to the program on Mac. I feel at loss when I find the photos are not organized from the latest to oldest. Another reason comes that it's a little complex for me, too many steps are needed to encode HEIC to JPG.
As an online HEIC decoder, Heictojpg.com is very easy and handy to use. Just drag and drop the HEIC photos to the frame box, and tap the CONVERT NOW button, all done. If you already have some unreadable HEIC photos on your Mac or Windows, this online HEIC to JPEG converter is a nice choice. Otherwise, you need to transfer your HEIC photos from iOS 11 iPhone to Mac/Windows with Photos first. Besides, the biggest problem of Heictojpg, or for all online HEIC to JPG converters is the security. Since you're sending photos from a public server, it can cause privacy disclosure.
