How Can I Remove EXIF Data From My Photos?

We live in the world driven by data. Data is everything in the world we live in today. Taking care of every bit of it is an avoidable responsibility.

What is EXIF data?

According to Wikipedia (Retrieved on October 16, 2017)

Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) is a standard that specifies the formatsfor images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.

In the early stages of the filming technology, the photographers had to carry pen and notepad to keep note of information such as shutter, speed, aperture, and date of the photos they shoot.

Today, digital cameras and cameras on mobile devices have an inbuilt capability to store this information with the photographs itself. Even geolocation data can be stored using GPS features in these devices.

These data can be used by photographers to examine how these photographs are shot for processing them. “Hackers” may take the advantage of this information for “foot-printing”. This information stored in photographs and videos are called EXIF data.

It is not advisable or wise to have this information being exposed to others. It is always better to take care of it.

It can be quite interesting if you are a bit of geek to extract this information from the images.

 

How Do I Read EXIF Data?

Even a simple image viewer has the capability to read some of this information such as date of shooting, ISO, and location.

In Windows, Explorer itself can read this information. Find the image, right-click and choose Properties.

Image editors, like Adobe Photoshop and The GIMP, can extract even more data.

Powerful tools like ExifTool in Kali Linux has the capability to read every detail of the image.

There are a lot of other tools that do the same. Online applications are also available.

 

Tips to Care EXIF Data

EXIF data help photographers to improve their techniques for coming up with better photographs. It helps them choose right lenses, focus time and all.

However, the selfies that one may take may not necessarily require these data. One may not like to share one’s geo-locations for security reasons. One may not want to share the information of the device being used. In such cases, extra-care should be taken.

It is important that one keeps GPS off while taking photographs unless required. Removing EXIF data before uploading to social networks is recommended.

In Windows, find the image, right-click and choose Properties. Click on Remove Properties and Personal Information.
