You can change the setting in your iOS device to turn off Live Photos
You can also set the camera to create jpgs instead
You can also create a lower quality png copy of your high quality image directly in your camera roll on iOS without any spyware converter (there is no free converter, you are paying with the embedded image information that is data mined, your photo contents also get used and belongs to them once you upload your image for conversion).

Settings- camera- formats
(Set this to most compatible for jpgs)
Settings- camera- preserve settings- Live Photo
(turn this setting on, so that is remembers in camera app that you turned off Live Photos and it will stay off permanently)

In photos if you want to make a forum friendly version of any photo
Get it to the size you want by pinching and zooming
Then take a screen shot of it
Then you edit the screen shot in you camera roll to trim it to size
This lower resolution image will be a PNG and will upload just fine without any embedded data like location.
This method is easy to capture a frame in a video for instance.
