What Is Image Metadata and Why Should You Remove It?
Image metadata is the hidden information embedded inside a photo file that describes how, when, and where the image was created. Every time you take a photo with a smartphone or digital camera, the device writes a block of metadata into the file. The most common format is EXIF — Exchangeable Image File Format — which stores the camera make and model, lens focal length, aperture, shutter speed, ISO sensitivity, date and time of capture, and often the GPS coordinates where the photo was taken. A single JPEG from a modern iPhone contains over 40 distinct EXIF fields. This data is invisible when you view the photo normally, but anyone who downloads the file can extract it in seconds using freely available tools like ExifTool, the command-line utility maintained by Phil Harvey that reads metadata from over 400 file formats.
Beyond EXIF, images can contain IPTC metadata — defined by the International Press Telecommunications Council — which includes fields for captions, keywords, copyright notices, creator names, and contact information. Professional photographers and news agencies use IPTC to tag images for asset management systems. There is also XMP — Extensible Metadata Platform, developed by Adobe — which stores editing history, color profiles, lens correction data, and software version information in an XML-based format embedded directly in the file. A single photo edited in Lightroom and exported from Photoshop might carry EXIF, IPTC, and XMP data simultaneously, adding 20-200 KB of hidden payload to the file. That overhead serves no purpose when the image is used as a website asset, a social media post, or an email attachment — and it introduces real privacy risks.
The privacy implications are serious. GPS coordinates in EXIF data can pinpoint your home, your workplace, or your child's school. Timestamps reveal your daily routine. Camera serial numbers can link photos across different platforms to the same physical device — and by extension, to the same person. Investigative journalists, domestic abuse survivors, and whistleblowers face tangible risks when metadata leaks location or identity information. Even for ordinary users, sharing a vacation photo with embedded GPS coordinates tells anyone who cares to look exactly which hotel room you stayed in. This tool strips all metadata from your images in the browser — EXIF, IPTC, XMP, and any other embedded data — so you can share files without accidentally sharing your personal information alongside them.
