Exiftool

Exiftool Exiftool is an open-source Android app for importing, processing, and managing image, audio, video, and file metadata. Edit tags, add geotags, restore timestamps, and batch analyze 100+ formats fast.

Exiftool

Exiftool is an open-source mobile utility that lets you import and work with images, audio, video, and many other file types without restrictions. You can modify files to match your preferences, attach geotags to photos and determine the related cities, and even restore photo timestamps. It also supports batch editing—so you can move or remove groups of metadata fields to fit your own workflow. After processing, you can freely choose the export format.

You can also read metadata from supported videos and files. The app is continuously updated, with new features added to keep the experience smooth and convenient.

Key Features

• 100% Free: Use it with no hidden charges, no sign-up required, and start analyzing files immediately.
• Simple File Upload: Drag & drop files or paste URLs to analyze metadata for any supported file type. Batch uploads are supported as well.
• Deep Analysis: Extract and view detailed metadata such as EXIF, XMP, IPTC, GPS coordinates, camera settings, and more.
• Wide Compatibility: Supports processing for 100+ formats, including RAW images, HDR, panoramas, documents, audio, video, and archives.
• Fast Processing: A high-performance engine reads and analyzes files in milliseconds, so even large batches produce results quickly.

Changelog

Version 13.59

• Added a new Canon RF lens (thanks Norbert Wasser).
• Decoded tags from Sony ILCE-7RM6 (thanks Jos Roost).
• Decoded a new FujiFilm tag (thanks Iliah Borg).
• Decoded additional DJI protobuf tags.
• Improved the error message shown when a wrongly encoded CSV or JSON file is read.
• Enhanced the -config option to support piped input using "-config -".
• Patched Composite SubSec date/time tags to ensure the correct EXIF group is used for SubSec and OffsetTime (prevents unintended use of non-standard XMP tags).



• Fixed a bug in -diff when comparing differences for specific tags and a requested tag was missing from the source file.

Version 13.58

• Added several new Nikon Z lenses (thanks Warren Hatch).
• Added new QuickTime MajorBrand values (thanks Herb).
• Added a new RAFCompression value.
• Introduced an undocumented -eh option (alias for -E / -escapeHTML).



• Decoded timed GPS from INNOVV N2 TS videos.
• Improved decoding of Canon ColorData for some models (thanks Iliah Borg).
• Renamed the RAFVersion tag to FirmwareVersion.
• Removed conversion for Garmin FIT DeviceIndex values.
• Properly parses XML CDATA and comment sections.
• Fixed an issue that could cause Garmin test failures on some systems.

FAQs

What format do I use for writing GPS coordinates, or how can I change the format of extracted GPS coordinates?

ExifTool accepts a flexible set of inputs for GPS coordinate entry. Any string that contains 1 to 3 floating-point numbers is valid. These numbers represent degrees, and optionally minutes and seconds, and the decimal precision can be any length.

EXIF GPS Coordinates

For EXIF coordinates, the direction is stored separately using either EXIF:GPSLatitudeRef or EXIF:GPSLongitudeRef.

• LatitudeRef can be written as a string containing "N", "North", "S", or "South", or by using a signed coordinate value (positive for the northern hemisphere, negative for the southern hemisphere).
• LongitudeRef works similarly, but uses E/East (positive) and W/West (negative).

XMP GPS Coordinates

For XMP, the direction is embedded into the values of XMP:GPSLatitude and XMP:GPSLongitude. West longitudes and south latitudes can be expressed either using negative numbers or by ending the string with "W" or "S".

Equivalent Latitude Examples (EXIF vs XMP)

Here are several equivalent ways to represent the same latitude in both EXIF and XMP:

• exiftool -exif:gpslatitude="42 30 0.00" -exif:gpslatituderef=S a.jpg
• exiftool -exif:gpslatitude="42 deg 30.00 min" -exif:gpslatituderef=S a.jpg
• exiftool -exif:gpslatitude=42.5 -exif:gpslatituderef=S a.jpg
• exiftool -xmp:gpslatitude="42 30 0.00 S" a.jpg
• exiftool -xmp:gpslatitude=42.50S a.jpg
• exiftool -xmp:gpslatitude=-42.5 a.jpg
• exiftool -xmp:gpslatitude="-42 -30" a.jpg

Important note: In the last example, the negative sign must apply to all coordinate components. The same idea applies to longitude formats as well. ExifTool will convert your input into the correct representation for the specific GPS tag being written.

Combined GPSCoordinates Input

Starting with ExifTool 12.22, combined lat/lon values can be written to GPSLatitude and GPSLongitude. ExifTool automatically extracts the latitude or longitude part from the provided string.

Writing EXIF GPS via a Single Tag

From version 12.36 onward, Composite:GPSPosition is writable, allowing EXIF GPS coordinates and their reference directions to be updated using one tag.

• # write all 4 EXIF GPS tags (version 12.36 and later)
  exiftool -gpsposition="42 30 0.00 S, 33 15 0.00 W"
• exiftool -gpsposition="-42.5, -33.25"

Composite:GPSLatitude/GPSLongitude Writable

With version 12.44 and later, Composite:GPSLatitude and Composite:GPSLongitude can be written together, so the coordinate and reference direction tags are set in one go. (In this case, you must specify the Composite group because these tags aren’t otherwise editable in the same way.)
