What Hidden Data Lurks Inside Your Photos?
A standard smartphone JPEG or HEIC photo contains: exact GPS latitude, longitude, and altitude down to the centimeter; full date and millisecond timestamp; device manufacturer, phone model, and serial number; and camera exposure details.
Doxxing attackers routinely extract GPS tags from uploaded photos to pinpoint victims' residential addresses, schools, and daily commute patterns.
Stripping EXIF via In-Browser Canvas Re-Encoding
When an image is drawn onto an HTML5 <canvas> element and exported using canvas.toBlob('image/jpeg'), the browser renders purely raw pixel data.
All non-pixel metadata headers (EXIF, IPTC, XMP, TIFF tags) are automatically discarded. This produces a sanitized image that contains zero traces of your physical location or hardware identity.
Step-by-Step Tutorial

Frequently Asked Questions
Do major social media platforms strip EXIF metadata automatically?
Twitter/X and Facebook strip EXIF from public image posts, but messaging apps, forums, blogs, and classified sites (eBay, Craigslist) often preserve raw metadata.
Does stripping EXIF metadata decrease image visual sharpness?
No. The image raster pixels remain crisp. Only text metadata headers stored in the file header are removed.
