View hidden EXIF metadata and securely strip it from photos offline.

100% Local Processing. Your photo never leaves your device.
System Definition BlockEvery photo you take with your smartphone contains hidden EXIF data, including exact GPS coordinates, timestamps, and device serial numbers. Use this zero-knowledge tool to securely view and permanently delete that metadata before sharing your photos online.
WebToolkit Pro is engineered for zero-trust environments. This utility processes your sensitive data entirely within your browser using Web Workers.
When an image is loaded, our tool reads the binary file header to extract the EXIF directories. To strip the data, the image is painted onto a hidden HTML5 Canvas element. Because the Canvas only cares about pixel color data and ignores metadata, re-exporting the image from the Canvas yields a mathematically clean, sanitized image file.
import EXIF from 'exif-js';
function getGpsCoordinates(imageElement) {
EXIF.getData(imageElement, function() {
const lat = EXIF.getTag(this, 'GPSLatitude');
const lon = EXIF.getTag(this, 'GPSLongitude');
if(lat && lon) console.log(`Location: ${lat}, ${lon}`);
});
}Most online EXIF tools require you to upload your image to their server. If the photo contains sensitive GPS data, you are actively exposing your location to a third party. Our tool is different: it runs entirely within your browser's memory, ensuring absolute privacy.
Cameras and smartphones embed EXIF (Exchangeable Image File Format) data to help organize photos. It includes the date/time, camera settings (aperture, ISO), and often the exact GPS coordinates where the photo was taken so your phone can map them.
Stripping EXIF data simply removes the text-based metadata headers from the file. However, because our tool repaints the image using an HTML5 Canvas to ensure a complete wipe, the image is re-encoded. We default to a 100% quality target to ensure no visible loss of fidelity.
