One of the comments shows how to remove stuff like exif data.
> magick convert IMG_1111.HEIC -strip -quality 87 -shave 10x10 -resize 91% -attenuate 1.1 +noise Uniform out.jpg
This will strip ALL exif metadata, change the quality, shave 10 pixels off each edge just because, resize to xx%, attenuate, and adds noise of type "Uniform".
Some additional notes:
- attenuate needs to come before the +noise switch in the command line
- the worse the jpeg quality figure, the harder it is to detect image modifications[1]
- resize percentage can be a real number - so 91.5% or 92.1% ...
So, AI image detection notwithstanding, you can not only remove metadata but also make each image you publish different from one another - and certainly very different than the original picture you took.
