Image Resizer is a great OSS app on F-Droid that supports converting between several image formats, including HEIC. It works locally, and does a bunch of other stuff, like (obv) resizing, stripping EXIF data, cropping, etc. It's nice looking, relatively small (9MB), and just a nicely done tool.
Looks promising, I'll try it out. Thanks!
I’m not sure of an app that does it (unless you want to use photoshop etc,but even that will likely try store it in the cloud).
I’d just ask the person to resend it. HEIC is the format used by iPhones. They can send it as a jpeg (they need to copy>paste it, not just press share).
another more explicit way to do that:
I'm on Android, I rely on Photo Editor for more than converting images but it's definitely able to open HEIC image and save them to another format.
