Answers to Questions

How to read EXIF Thumnnail data?

Indicate the image file to upload (JPG, PNG or other EXIF compatible format) and dCode will automatically read the EXIF data and especially the Thumbnail field containing the thumbnail if it exists, otherwise, it will not return any results.

What is the Thumbnail EXIF metadata?

The EXIF metadata format applies to image files and allows them to store various additional information (in addition to the image pixel data) such as information on the author, source etc. There is a field dedicated to storing a thumbnail which allows you to save a smaller and quicker version of the image.

Extracting the data may return an unreadable image file.

Why extracting EXIF Thumnnail data?

Indicate the image file to upload (JPG, PNG or other EXIF compatible format) and dCode will automatically read the EXIF data and especially the Thumbnail field containing the thumbnail if it exists, otherwise, it will not return any results.

Sometimes the thumbnail can reveal information, it happened that some images were blurred or censored but their thumbnail was not updated, so it is possible to guess the original content.
