Apple switched to HEIC as the default photo storage format for the iPhone starting 2017. This image format is yet to be widely accepted. So a lot of apps do not support it including many built-in gallery apps. If you receive photos from someone who owns an iPhone, your Android may fail to open the photo. In this case, you need an app or service to convert the HEIC image to JPG image to see.
Google Photos supports the HEIC format of photos, but only if someone uploads it from their iPhone by using the Google Photos app. If you received photos from any other mean, you need to convert them to the JPG format before you could use.
If you are looking for a good app or service to convert HEIC to JPG format, you can use any of the given ways to convert HEIC to JPG on your Android device.
