What is a .mos file?
A .mos file is a Leaf Mosaic Raw Image. This is an image format — a picture, drawing or graphic.
How to open a .mos file
- GIMP (free) and IrfanView open a very wide range of image formats, including obsolete ones.
- XnView MP is the best bet for unusual or legacy image types.
- Your operating system's built-in viewer may work for mainstream formats.
The registry records this extension against Leaf Mosaic Raw Image, so software from that family is the most likely match.
How to convert a .mos file
- Open it in GIMP or XnView and export as .png (lossless) or .jpg (smaller).
