I use "exifcleaner" to clean metadata from media

I use the above, it's reliable.

If you're feeling twitchy, another option is

https://gitlab.com/juanitobananas/scrambled-exif/tree/HEAD

Which replaces the exif and other metadata with garbage.

I'm a longtime dev but never work with images. What's the disadvantage or danger (or whatever) of the metadata? Can metadata execute?

[–] notnotmike@programming.dev 0 points 1 year ago

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
