The zsj file extension is associated with Zerene Stacker, focus-stacking software developed by Zerene System. The software combines multiple photographs focused at different distances to produce an image with greater depth of field.
A zsj file contains information about a Zerene Stacker project and the settings used for the stacking work. It is a native Zerene Stacker project format rather than a rendered image format.
Zerene Stacker is available for Microsoft Windows, macOS and Linux. The zsj format is intended for saving and reopening projects in Zerene Stacker.
Open zsj files with Zerene Stacker on Microsoft Windows, macOS or Linux. Use the software's Open command or associate the file with Zerene Stacker in the operating system.
If the project refers to source images stored separately, those images must also remain available to Zerene Stacker.
A zsj file is not normally converted to another project format. Open it in Zerene Stacker to access the project and save or export the resulting stacked image in a supported image format.
