I use the above, it's reliable.
If you're feeling twitchy, another option is

Which replaces the exif and other metadata with garbage.

I use "exifcleaner" to clean metadata from media
https://github.com/szTheory/exifcleaner
I'm a longtime dev but never work with images. What's the disadvantage or danger (or whatever) of the metadata? Can metadata execute?
I can't say whether it can execute, but the metadata is a privacy concern if you are posting online. Depending on the camera taking the picture it can include the model of the phone, date, or even GPS information
Just to herd a warning then from a Dev perspective: you want to remove them before interacting, not just opening.
I can send files without ever opening them and the sharing would keep the meta data if you'd not open the files manually with the cleanup tool.
Personally I've had a camera app a while back that I could configure which meta data it saved but I simply stopped sharing photos on social media and so this become s non issue for me :)
