Metadata Types

Images can contain different format types of metadata. Photo Meta Edit provides you to add, remove and edit metadata of the following format types ②, ③, ④, ⑤ and ⑥.

The Metadata Type List shows types of metadata which are embedded in the files you selected. Contents of metadata, which are selected in the Metadata Type List, will be displayed on the right side of the Metadata Type List.

  1. Favorites (for Tagged-Format Metadata)
    You can arrange only the metadata items (TIFF, Exif and GPS-related) that the user wants to see/edit in order of preference.
  2. HEIC Property
    You can set Image Orientation of HEIC files.
  3. Comments (JPEG only)
    You can use ASCII characters only.
  4. JFIF (JPEG only)
    JFIF (JPEG File Interchange Format) information.
  5. TIFF (Tagged-Format Metadata)
    The tag information format defined in TIFF Rev. 6.0. The structure is such that Exif and GPS are in TIFF.
    Exif and GPS are usually recorded in this format. The tag numbers of Exif and GPS items are defined by CIPA.
    (To avoid confusion, this metadata format is called Tagged-Format Metadata in this User Guide)
  6. XMP
    XMP (Extensible Metadata Platform) is defined by Adobe systems Inc. JPEG and Tiff images can contain TIFF, Exif and GPS metadata in XMP format.

Tips for Image Orientation

Image Orientation items exist in the Tagged-Format TIFF, XMP > TIFF, and HEIC Property. If each setting is different, the orientation displayed may differ depending on image viewer apps. And also depends on the type of image. The settings for each should be the same in each file.

Photo Meta Edit displays images in the same orientation as Apple's Preview app.
