if you get a message saying 'Not a valid JPEG'), then ExifTool can not be used to repair the image. Note: ExifTool will not modify the JPEG image data, so if the image itself is corrupted (eg.

The 'ICC_Profile' tag is also marked as unsafe, but is not part of the EXIF so it isn't covered by the 'Unsafe' shortcut and must be specified separately.Īfter repairing an image like this you should be able to write to it without errors, but note that some metadata from the original image may have been lost in the process. JPEG images may also contain an ICC color profile which should be preserved. The 'Unsafe' tag is a shortcut for unsafe EXIF tags in JPEG images which are not normally copied. This command deletes all metadata then copies all writable tags that can be extracted from the original image to the same locations in the updated image. There is an Exiftool FAQ alternative, that tries to repair JPEG file-metadata and preserve existing tags: exiftool -all= -tagsfromfile -all:all -unsafe -icc_profile my-image.jpgĮxifTool may be used to fix metadata problems in JPEG images by deleting all metadata and rebuilding it from scratch.
