That will save the image back as JPEG. Alternatively, email yourself the photos. If you do this, then regardless of whether they were shot in HEIC or not, Apple will email over the JPEG version.

The downside is that RAW files take up a lot of space and require extra work to process in post ... As you can see from the image comparison above, the JPEG is naturally a nicer-looking image.
