Answers to Questions (FAQ)
What is EXIF data? (Definition)
EXIF (Exchangeable Image File Format) data is metadata embedded in digital image files, including JPEG, TIFF, and RAW photos. It automatically records technical and descriptive information related to the image. This metadata can include: the date and time the photo was taken, the camera or smartphone model, shooting settings (aperture, shutter speed, ISO sensitivity, focal length, etc.), GPS geolocation, image orientation, and information about the photographer or software used.
How to read EXIF metadata?
Choosing and uploading an image file containing EXIF data and / or XML metadata. The dCode reader/extractor will automatically read whatever is included in the file if there is any, otherwise no results will be returned.
Example: The following JPG image contains a user comment dCode 
The extraction of EXIF data is exhaustive, but some data may be unreadable.
Almost anything can be stored in these metadata fields, including fake or unrelated data. There is even an exif thumbnail field for storing an image in the image.
To save bandwidth (and sometimes to protect privacy), metadata is often removed on images available on the Internet.
How to remove EXIF metadata?
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.
Why using EXIF data?
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.
How to tell if an image has been modified?
It is sometimes possible to detect that an image has been modified by analyzing its EXIF metadata.
If the software used to save the image is Photoshop, GIMP, or Lightroom, then it is highly likely that retouching has been performed.
If the modification date differs from the date the image was taken, then the image may have been modified afterward.
If there are inconsistencies between the declared camera and the shooting settings, then the image may have been manipulated.
Note: EXIF metadata can be deleted or falsified relatively easily.
Where is EXIF data stored?
EXIF data is stored inside the files. Image formats usually have metadata compartments in their format specifications.
What is the APP1 marker?
The EXIF metadata format uses a marker inside image files, and APP1 is the one that is generally used to store EXIF data.
What are the differences between EXIF data and IPTC 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.
Why do internet images generally not contain any EXIF data?
Many websites, social networks, and messaging services automatically remove EXIF data when images are uploaded.
This removal reduces file size, speeds up page loading, limits privacy risks (geolocation), and prevents the unintentional disclosure of personal information.
Some platforms also completely recompress images, which often destroys the original metadata.
