Unspecified File to Image Conversion

Looking for a Matlab expert capable of coding a system that can convert an unspecified type of file to an image. The original file format and the desired image format are undefined, thus the freelancer needs to manage variable inputs. I am unable to provide a specific size for the files that will be converted, so the system should be capable of handling files of different sizes.

Skills and Experience Required:
- Proficiency in Matlab
- Experience with file conversion tasks
- Ability to deal with variable inputs
- Ability to work with large files
