TN1 to BMP Conversion: FAQ

What are TN1 files?

TN1 is an archaic format associated with Atari ST — a brand of personal computers that used to be popular in the 1980s and 1990s. TN1s represent compressed bitmap images created or edited using image software designed for Atari computers, such as Tiny Stuff or Tiny View. Opening such files with currently available image viewers is probably difficult, so conversion might be the best option.

What are BMP files?

The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.
