Remove EXIF Data

This lesson is part of Web Developer Tools · All levels

Summary

Remove EXIF deletes metadata from image files before sharing, so that camera information, GPS location, and device serial numbers do not get shared. Removing metadata without re-encoding doesn't change the pixels, but the tool that recompresses can reduce the quality. After cleaning, re-examine the orientation and important details of the image.

Key points

Metadata can contain GPS locations, camera models, and time taken
Deleting metadata helps reduce the risk of privacy
The lossless method does not change the pixel value, whereas re-encoding can lower the quality
The file size may decrease slightly after the metadata is deleted
Save the original file if the metadata is still needed for archiving
