This is a tool for anonymizing photographs taken at protests.
Tool lives at : https://everestpipkin.github.io/image-scrubber/
It will remove identifying metadata (Exif data) from photographs, and also allow you to selectively blur parts of the image to cover faces and other identifiable information.
Hit the open button to open a photograph. The program will display the data it is removing.
Click okay, and you can then save the scrubbed image by hitting save or right clicking on it and saving it. Maximum size is 2500x2500 pixels - larger images will be scaled down.
Dragging on the image will blur it. You can change your brush size and the intensity of the blur via the sliders. The blur function has built-in pixelization and noise as added security layers.
All processing happens directly in the browser- no information is stored or sent anywhere.

My code is a mess right now but utility over cleanliness, will fix up in the coming days after the more critical work is over.
