The onportrait file extension is used by ON1 Photo, photo-editing software from ON1 for Microsoft Windows and macOS.
An onportrait file is a software-specific data file used by ON1 Photo. It is part of the application's working data rather than a general-purpose image format, and its internal contents are intended to be handled by ON1 Photo.
Use ON1 Photo on Windows or macOS to work with an onportrait file. Supporting files may be handled automatically by the application.
If the file does not open directly from the application, it may be supporting data rather than a standalone document.
An onportrait file is not intended for direct conversion to another file format.
To create a shareable image or other supported output, open the associated work in ON1 Photo and use the application's export function.
