Removing metadata from files before submitting

Photos and documents submitted to vendor order forms carry embedded metadata — information written into the file itself that is not visible in the image but can be read by anyone who examines the file. Here is what that metadata contains and how to remove it.

What photo metadata includes

A JPEG photo from a modern smartphone typically embeds: the device model and serial number, the date and time the photo was taken, GPS coordinates if location services were enabled, software version, and sometimes the Apple ID or Google account associated with the device. All of this is encoded in the EXIF data section of the file.

Most vendors do not examine this data, and there is no practical scenario where a vendor reading your EXIF data creates a problem. But for buyers who prefer to minimize any personally identifying data in files they share with third-party services, stripping EXIF is a simple precaution.

How to remove it

On Windows: right-click the file, Properties, Details tab, "Remove Properties and Personal Information" at the bottom. Select all properties and click OK. This creates a cleaned copy.

On Mac: the free app ImageOptim strips EXIF during file optimization. Alternatively, the Preview app's Export function does not preserve all EXIF fields depending on settings.

Cross-platform: ExifTool is the most thorough command-line option. The command exiftool -all= filename.jpg removes all metadata and modifies the file in place. A free web tool called Exif Purge handles it without software installation.

What to check after removal

After stripping metadata, verify the image quality is intact — some tools affect image data along with metadata. Also verify the file is still a valid JPEG (not accidentally converted to a different format). ExifTool's -list command shows remaining fields after a strip operation.

Turning off location services for the camera app before taking photos prevents GPS coordinates from being embedded in the first place, which is the simplest ongoing practice.
