What is a TN file?
A .TN file is primarily a thumbnail image file. Digital cameras, operating systems like Google Android OS, and software such as Adobe Photoshop or Google Picasa create these files. They store a small preview of a larger image to help systems load galleries faster. Sometimes, a .TN file contains a standard JPEG image thumbnail. Other times, it uses a JSON structure to store thumbnail metadata. Additionally, an LG Phone Image created by LG mobile devices can also use the .TN file extension.
How to open TN files?
Because a .TN file has multiple possible meanings, it is not always clear which program you need. Many .TN files open in standard image viewers if you rename the extension to .JPG. However, if the file contains structured data instead of raw image data, you might need a text editor like Notepad++ to read its contents.
