Tiny Stuff format (or Tiny format) is an RLE-compressed image format used on Atari ST computers. It is associated with a conversion utility (Tiny Stuff) and viewer (Tiny View) by David Mumper.

Format

The first byte of the file is a code indicating the image type. Palette color animation is optionally supported.

Code	Dimensions	Colors	Animated	Filename extensions
0	320×200	16	No	.TNY, .TN1
1	640×200	4	No	.TNY, .TN2
2	640×400	2	No	.TNY, .TN3
3	320×200	16	Yes	.TNY, .TN1, unofficially .TN4
4	640×200	4	Yes	.TNY, .TN2, maybe .TN5
5	640×400	2	Yes	.TNY, .TN3, maybe .TN6

Files consist of a 37-byte (if not animated) or 41-byte (if animated) header, followed by a "control" segment and a "data" segment which together form the compressed image data.
