There is only one file type that uses the .TGA extension:
A TGA file is an image saved in the Targa raster graphic format designed by Truevision. It supports 8, 16, 24, or 32 bits per pixel at a maximum of 24 bits for RGB colors and an 8-bit alpha channel. TGA files are used for various types of images, such as digital photos and textures referenced by 3D video games.
You can open TGA files with various image editors, such as Adobe Photoshop (multiplatform), ACD Systems Canvas (Windows), Corel Painter (multiplatform), and GIMP (multiplatform).
If you are a Mac user, you can open TGA files with Apple Preview or Apple Photos, which come bundled with macOS. You can also convert TGA images to .JPEG, .PNG, .HEIC, .TIFF, and .PDF formats with Preview.
