Troubleshooting & Diagnostic Fixes
1 SolutionsHow to Strip EXIF GPS Coordinates and Camera Metadata Before Publishing
Symptom: Photos uploaded to websites leak photographers’ residential locations in binary tags.
Solution: Process images through client-side HTML5 canvas redrawing or binary EXIF header stripping prior to publishing.
