-## Why Strip Metadata?
-
-Okay, so you want to strip metadata from your photos. Perhaps you take pictures
-of very rare birds, and the location metadata is a gold mine for poachers, or
-perhaps you're just privacy-oriented like me and prefer to strip metadata from
-publicly-available images.
-
-There are various components of image metadata that you may want to delete
-before releasing a photo to the public. Here's an incomplete list of things I
-could easily see just by inspecting a photo on my laptop:
-
-- Location (Latitude & Longitude)
-- Dimensions
-- Device Make & Model
-- Color Space
-- Color Profile
-- Focal Length
-- Alpha Channel
-- Red Eye
-- Metering Mode
-- F Number
-
-Regardless of your reasoning, I'm going to explain how I used the `exiftool`
-package in Linux to automatically strip metadata from all images in a directory
-(+ subdirectories).
-
-## Installing `exiftool`
-
-First things first: we need to install the tool. I'm running Debian 11 on my
-server (Ubuntu will work the same), so the command is as simple as:
-
-```sh
-sudo apt install exiftool
-```
-
-There are different tools that can accomplish the same thing across
-distributions, but I really only care to test out this one package.
-
-## Recursively Strip Data
-
-I actually use this tool extensively to strip any photos uploaded to the website
-that serves all the images for my blog (`img.cleberg.net`).
-
-The following command is incredibly useful and can be modified to include any
-image extensions that `exiftool` supports:
-
-```sh
-exiftool -r -all= -ext jpg -ext png /path/to/directory/
-```
-
-The output of the command will let you know how many directories were scanned,
-how many images were updated, and how many images were unchanged.
