EXIF Data

EXIF data (Exchangeable Image File Format) is information embedded in digital image files, such as photos, to provide additional detail. This information includes metadata such as the date and time of the shot, camera settings, geolocation and many more.

Choosing and uploading an image file containing EXIF data and / or XML metadata to extract and dCode will automatically read whatever is included in the file if there is any, otherwise no results will be returned.

The data in the image files is linked to various information on it such as the author, the photographer, the camera used, the location, etc.

The extraction of EXIF data is exhaustive, but some data may be unreadable.

Upload a file and click on the Delete button.

A simple method is sometimes to re-save the image, many software ignore metadata.

Image compression software almost systematically deletes EXIF data because it takes up space deemed useless.

EXIF data is used for various purposes. They store valuable information about the shot, such as camera settings, lens used, exposure, white balance, etc. This information can be useful for photographers to analyze and improve their techniques, or for users to organize and sort their image collections.

Metadata can also be used to store any text, so ideal for hiding secret messages not visible at first sight.

EXIF data is stored inside the files. Image formats usually have metadata compartments in their format specifications.

The EXIF metadata format uses a marker inside image files, and APP1 is the one that is generally used to store EXIF data.

EXIF data and IPTC data are two types of metadata used in digital photography. EXIF data is generated automatically by the camera and contains technical shooting information, while IPTC (International Press Telecommunications Council) data is metadata added manually by the user and contains editorial information such as the title, description, copyright, etc.
