ExifTool

ExifTool is a widely used tool for {read, write, edit} metadata in image files. It's available for {Windows, Mac, Linux}.

View Metadata

# show metadata of a image file
exiftool myPhoto.jpg

# show metedata for all *jpg files in current dir
exiftool -ext jpg .

# show metedata for all *jpg files in current dir and subdirs
exiftool -r -ext jpg .

Here's sample metadata in jpg file and mp3 file:

• exiftool sample output on JPG file: metadata_sample_exif.txt
• exiftool sample output on MP3 file: metadata_sample_id3.txt

Remove Metadata

# remove all metadata of a image file
exiftool -all= -overwrite_original photo.jpg

# remove all metadata of all *jpg files in current dir
exiftool -all= -overwrite_original -ext jpg .

# remove metedata for all *jpg files in current dir and subdirs
exiftool -all= -r -overwrite_original -ext jpg .

The -ext jpg is case-sensitive. So, you might use -ext JPG or -ext jpeg or -ext png.

Remove just GPS data

# remove all GPS metadata of *jpg files in current dir
exiftool -gps:all= *.jpg
