There is really no way how you could get a JPG picture out a THUMBDATA3 file. It is just a cache file that contains thumbnail data for a picture that exist, or once existed in your Android phone. The problem is in the fact that .thumbdata3 file contains data from ALL pictures, not just single one, so there is no way how to get a single one, even in thumbnail form.
Simply put, it is impossible to convert THUMBDATA3 to JPG directly.
Thus, there is no so-called thumbdata3 to jpg converter or a free online .thumbdata3 to .jpg conversion tool.

The thumbdata3 file format is a cache file used by Android devices to store thumbnail images. These files are typically found in the DCIM folder of an Android device and are used to speed up the loading of image thumbnails in the gallery app. However, they do not contain actual image data that can be directly converted to a viewable format like JPG.
