What Is Image Metadata and What Does This Tool Do About It?
Image metadata is the hidden information a camera or phone writes into a photo file alongside the pixels. The most common form is EXIF — Exchangeable Image File Format — which records the camera make and model, lens, focal length, aperture, shutter speed, ISO, the exact date and time of capture, the editing software used, and, on most phones with location services enabled, the GPS coordinates where the shot was taken. None of it is visible when you look at the picture, and all of it travels with the file when you email it, upload it, or post it somewhere.
That is a genuine privacy exposure rather than a theoretical one. GPS coordinates can identify a home, a workplace, or a school. Timestamps sketch out a routine. Camera and software fields can tie photos posted in different places to the same device. This tool does two things about it: for JPEG files it parses the embedded EXIF block and shows you, tag by tag, exactly what is in there — with GPS entries highlighted — and then it produces a clean copy of the image with the metadata gone.
The removal method is worth understanding because it shapes what you get back. The image is drawn onto an HTML canvas and exported again from the pixels alone, which means nothing but pixel data survives: EXIF, GPS, XMP, embedded thumbnails, and the ICC color profile all disappear together. It is an all-or-nothing operation with no option to keep selected fields. JPEG output is re-encoded at quality 0.95, which is visually indistinguishable in normal use but is still a lossy pass, so you should always keep your original master. PNG output is re-encoded losslessly. Every step, from parsing to export, runs inside your browser — the file is never uploaded anywhere.
