This document contains a complete list of ExifTool tag names, organized into tables based on information type. Tag names are used to reference specific meta information extracted from or written to a file.
The tables listed below give the names of all tags recognized by ExifTool. They contain a total of 25775 tags, with 16465 unique tag names.
Tag ID, Index# or Sequence is given in the first column of each table. A Tag ID is the computer‑readable equivalent of a tag name, and is the identifier that is actually stored in the file. Index# refers to the offset of a value when found at a fixed position within a data block (# is the multiplier for calculating a byte offset: 1, 2, 4 or 8). These offsets may have a decimal part which is used only to differentiate tags with values stored at the same position. Sequence gives the order of values for a serial data stream.
A Tag Name is the handle by which the information is accessed in ExifTool. In some instances, more than one name may correspond to a single tag ID. Case is not significant for tag names. A question mark ("?") after a tag name indicates that the information is either not understood, not verified, or not very useful – these tags are not extracted by ExifTool unless the Unknown (-u) option is enabled. Be aware that some tag names are different than the descriptions printed out by default when extracting information with exiftool. To see the tag names instead of the descriptions, use exiftool -s.
The Writable column indicates whether the tag is writable by ExifTool. Anything but a "no" in this column means the tag is writable. A "yes" indicates writable information that is either unformatted or written using the existing format. Other expressions give details about the format of the stored value, and vary depending on the general type of information. The format name may be followed by a number in square brackets to indicate the number of values written, or the number of characters in a fixed‑length string (including a null terminator which is added if required).
A plus sign ("+") after an entry in the Writable column indicates a List tag which supports multiple values and allows individual values to be added and deleted. A slash ("/") indicates a tag that ExifTool will Avoid when writing. These will be edited but not created if another same‑named tag may be created instead. To create these tags, the group should be specified. A tilde ("~") indicates a tag this is writable only when the print conversion is disabled (by setting PrintConv to 0, using the -n option, or suffixing the tag name with a "#" character). An exclamation point ("!") indicates a tag that is considered Unsafe to write under normal circumstances. These tags are not written unless specified explicitly (ie. not when wildcards or "all" are used), and care should be taken when editing them manually since they may affect the way an image is rendered. An asterisk ("*") indicates a Protected tag which is not writable directly, but is written automatically by ExifTool (often when a corresponding Composite or Extra tag is written). A colon (":") indicates a Mandatory tag which may be added automatically when writing. Normally MakerNotes tags may not be deleted individually, but a caret ("^") indicates a Deletable MakerNotes tag.
The HTML version of these tables also lists possible Values for discrete‑valued tags, as well as Notes for some tags. The Values are listed with the computer‑readable values on the left of the equals sign ("="), and the human‑readable values on the right. The human‑readable values are used by default when reading and writing, but the computer‑readable values may be accessed by disabling the value conversion with the -n option on the command line, by setting the PrintConv option to 0 in the API, or on a per‑tag basis by adding a hash ("#") after the tag name.
Note: If you are familiar with common meta‑information tag names, you may find that some ExifTool tag names are different than expected. The usual reason for this is to make the tag names more consistent across different types of meta information. To determine a tag name, either consult this documentation or run exiftool -s on a file containing the information in question.
(This documentation is the result of years of research, testing and reverse engineering, and is the most complete metadata tag list available anywhere on the internet. It is provided not only for ExifTool users, but more importantly as a public service to help augment the collective knowledge, and is often used as a primary source of information in the development of other metadata software. Please help keep this documentation as accurate and complete as possible, and feed any new discoveries back to ExifTool. A big thanks to everyone who has helped with this so far!)
This table lists information extracted by ExifTool from JPEG images. See <https://www.w3.org/Graphics/JPEG/jfif3.pdf> for the JPEG specification.

EXIF stands for "Exchangeable Image File Format". This type of information is formatted according to the TIFF specification, and may be found in many image and video formats.
The table below lists all EXIF tags. Also listed are TIFF, DNG, HDP and other tags which are not part of the EXIF specification, but may co‑exist with EXIF tags in some images. Tags which are part of the EXIF 2.32 specification have an underlined Tag Name in the HTML version of this documentation. See <https://web.archive.org/web/20190624045241if_/http://www.cipa.jp:80/std/documents/e/DC-008-Translation-2019-E.pdf> for the official EXIF 2.32 specification.
Sample entries: (full table contains 300+ tag IDs)

The tags listed below are part of the International Press Telecommunications Council (IPTC) and the Newspaper Association of America (NAA) Information Interchange Model (IIM). This is an older meta information format, slowly being phased out in favor of XMP – the newer IPTCCore specification uses XMP format. IPTC information may be found in many image formats.
IPTC information is separated into different records, each of which has its own set of tags. See <http://www.iptc.org/std/IIM/4.1/specification/IIMV4.1.pdf> for the official IPTC IIM specification.
Sample records:
| Record | Tag Name | Writable |
|---|---|---|
| 1 | IPTCEnvelope | IPTC EnvelopeRecord |
| 2 | IPTCApplication | IPTC ApplicationRecord |
… (many sub‑tags in each record) …
XMP stands for "Extensible Metadata Platform", an XML/RDF‑based metadata format which is being pushed by Adobe. Information in this format can be embedded in many different file types.
The XMP tags are organized according to schema Namespace in the following tables. The ExifTool family 1 group names are derived from the namespace prefixes by adding a leading "XMP‑".
Namespaces: (full list of 50+ namespaces)
aas, acdsee, album, apple‑fi, ast, aux, cc, cell, crd, creatorAtom, crs, dc, Device, dex, DICOM, digiKam, drone‑dji, dwc, exif, exifEX, expressionmedia, extensis, fpv, GAudio, GCamera, GCreations, GDepth, getty, GFocus, GImage, GPano, GSpherical, ics, iptcCore, iptcExt, LImage, lr, mediapro, microsoft, MP, MP1, mwg‑coll, mwg‑kw, mwg‑rs, nine, pdf, pdfx, photomech, photoshop, PixelLive, plus, pmi, prism, prl, prm, pur, rdf, sdc, swf, tiff, x, xmp, xmpBJ, xmpDM, xmpMM, xmpNote, xmpPLUS, xmpRights, xmpTPg

These GPS tags are part of the EXIF standard, and are stored in a separate IFD within the EXIF information.

The extra tags provide extra features or extra information extracted or generated by ExifTool that is not directly associated with another tag group. The Group column lists the family 1 group name when reading. Tags with a "‑" in this column are write‑only.
… (list of extra tags) …
The values of the composite tags are Derived From the values of other tags. These are convenience tags which are calculated after all other information is extracted. Only a few of these tags are writable directly, the others are changed by writing the corresponding Derived From tags.

Shortcut tags are convenience tags that represent one or more other tag names. They are used like regular tags to read and write the information for a specified set of tags.

The Metadata Working Group (MWG) recommends techniques to allow certain overlapping EXIF, IPTC and XMP tags to be reconciled when reading, and synchronized when writing. The MWG Composite tags below are designed to aid in the implementation of these recommendations. As well, the MWG defines new XMP tags which are listed in the subsequent tables below.
