### Remove EXIF/GPS data from your photos before you upload them.

## What is EXIF?

[EXIF](http://en.wikipedia.org/wiki/Exchangeable_image_file_format)

is a type of metadata that is embedded in photo files from most types

of cameras and phones.

This metadata includes information about the device used to capture the photo,

but also often includes the GPS coordinates of where the photo was taken.

Many users unknowingly share this information with the general public

and site/app owners when uploading photos online.

This has been a common vector of privacy lapses, including cases where

journalists have unintentionally published photos with geotagging data intact.

Recent press has also revealed the NSA’s collection of EXIF data in

its [XKeyscore](http://en.wikipedia.org/wiki/XKeyscore) program.

## What is ExifExodus?

ExifExodus is a small piece of

[open-source code](https://github.com/dmotz/ExifExodus) that

runs directly in your browser and strips EXIF data out of your photos before

you upload them.

## How does it work?

You can run ExifExodus whenever you’re uploading photos by using its

bookmarklet (available on the [site](https://oxism.com/ExifExodus/))

When ExifExodus encounters a JPG file, it will remove the EXIF data by

copying the pixels to a new image file, similar to taking a screenshot of

something.

Alternatively, you can drop your files in the dropzone at the top of the

[site](https://oxism.com/ExifExodus/)) and receive versions free of EXIF data. You can

then save these new files and upload them wherever you’d like.

## Is EXIF without merit?

That’s certainly not the implication of this project. Metadata adds

another dimension to photos and is valuable for preserving context.

This project aims to educate and give users a choice in the matter of sharing

it with specific services (and the web at large).

## Doesn’t Facebook (etc.) remove EXIF data before displaying photos?

Yes. Although this prevents the general public from accessing your EXIF data,

you should be aware that the end recipient is free to use or store the metadata

before removing it.

## Any caveats?

The ExifExodus bookmarklet won’t work with any site that uses Flash

(or any other proprietary plugins like Silverlight) to upload files.

For such sites, use the dropzone converter, save the output files, and upload

those instead.

ExifExodus only works with JPG files (which is the most common image

format to carry EXIF metadata).
