About the MOS file format
MOS is a camera RAW format used to retain image data for photographic development and conversion.
The guide and converter lists are generated from the live HEIC.now catalog, so every conversion shown here is an available workflow.
Why MOS files are used
MOS File Format files belong to the camera raw family and use the .mos extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about MOS
File structure
MOS has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for MOS varies between browsers, operating systems and editing applications.
Original files
Keep the original MOS when future editing or maximum retained information matters.
How MOS conversion works
Converting MOS decodes or renders the source and then encodes the result in the selected destination format.
Review the converted file before replacing the source because format-specific features may not transfer.
heic.now accepts MOS as an input and converts it to supported outputs.
MOS compatibility and software support
Check that the receiving browser, app or service supports MOS before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
MOS and related formats

- Publishing: Prepare content for a website, app or content-management system.
- Editing: Move content into a format supported by the next editing application.
- Archiving: Keep the original and create practical access copies for everyday use.
