I’ve been using mat2, which is the first recommended option on PrivacyGuides.com, to remove metadata. Is there any drawback to this compared to ExifTool, which is at the bottom of the page? mat2 relies on ExifTool, but only for removing metadata that isn’t a PDF, audio file, image, svg, or video. I usually use mat2 for videos, which utilizes FFmpeg to remove metadata. I don’t think ExifTool uses FFppeg, but I could be wrong.

One weird thing, I probably shouldn’t, but I still use ExifCleaner, which is an outdated Electron-based drag-and-drop metadata removal tool. After I run a video through mat2 and then through ExifCleaner, ExifCleaner says there were 60 metadata entries on the video file, but it reduces it to 59. This means mat2 seems to not remove all possible metadata.
