Master Your Image Data: The Best Free & Open-Source Photo Metadata Editors
Every time you snap a photo, your camera records a wealth of hidden information right into the image file. This data, known as metadata, includes everything from the camera model and shutter speed to the date, time, and even the precise GPS location where the picture was taken. While this information is incredibly useful for organizing your photo library, it can also pose a significant privacy risk if not managed properly.
Whether you’re a professional photographer needing to add copyright information or a casual user wanting to protect your privacy, a powerful photo metadata editor is an essential tool. Fortunately, you don’t need to spend a fortune to gain control over your data. We’ve curated a list of the best free and open-source tools designed to help you view, edit, and remove image metadata with ease.

Actionable Security Tip: Protect Your Privacy by Removing Metadata
Before you share any photo online—whether on social media, a messaging app, or a public forum—it’s crucial to consider the hidden data it contains. The most sensitive piece of metadata is often the GPS location (geotag), which can reveal your home address, workplace, or other private locations.
To protect yourself:
- Use one of the tools above to strip metadata before sharing. Most have a “remove metadata” or “strip all” function. For a quick export, GIMP is an excellent choice.
- Turn off location services for your smartphone’s camera app. This prevents GPS data from being embedded in your photos in the first place. Check your phone’s settings under
Privacy > Location Services. - Be aware that some social media platforms automatically strip metadata, but many do not. It is always safest to remove it yourself before uploading to ensure your privacy is protected.
By taking control of your photo metadata, you not only improve your workflow and organization but also safeguard your personal information in an increasingly digital world.
