What is Exif Data?
Exchangeable Image File Format (Exif) is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones).
The Privacy Risk
When you take a photo with your phone, it often records your exact GPS location (latitude and longitude) inside the image file. If you upload this "original" photo to a blog or send it via email, anyone can download it and see exactly where you were standing.
How to Securely Handle Photos?
Most social media platforms strip this data automatically, but direct file sharing (AirDrop, iCloud, Email) often preserves it.
Solution: Use ShrinkFile to compress and convert your high-resolution HEIC/JPG photos locally, ensuring your originals stay private while shared versions are optimized.
