Open TN File

The TN file extension and format is a type of image file used by some LG brand mobile phones.

The TN file saves an image taken by the phone and is saved on the memory card (MicroSD) of the device.

Because the TN file is a proprietary format, it cannot be viewed with traditional image viewers, but must be sent from the phone to the user's email address to view it on a computer as a JPG file.

It has been reported that, in theory, it is possible to open a TN file, simply by changing the TN extension to a standard extension, such as JPG.

This type of TN file should not be confused with those related to Tracor Northern.

The Tracor Northern TN format is described by the U.S. Geological Survey and is used by the Tracor Northern electron microscopy test kit to record images in a 512x512 pixel, 8-bit gray scale format.

In any case, these images use the SEM extension, instead of TN.

How to change TN extension to JPG?

In any modern operating system, the following steps are feasible to change the extension of any file:
Locate the file (Important: the possibility to see the extension must be checked)
Right click on the file
Click on "Rename" or "Change File Name"
Once the extension is changed, you just have to open the file with your preferred application.

Software to open a TN file
