Why this matters
JPG images commonly carry share-sensitive details
JPEG photos are one of the most common formats for phone cameras, DSLRs, and image sharing. They can store far more than pixels, including the time the photo was taken, the device model, editing software, and sometimes the exact shooting location.
If you publish portfolio work, client proofs, marketplace photos, or personal pictures, cleaning that data gives you more control over what travels with the file.
