Using parameters with convert-to for document to image export

[stefanu123]

I need to create images of all pages of a document using the command line. Using the UI or changing parameters via the UI is NOT an option; all needs to be done using the CLI.

This command line works, but saves only the first page.

soffice --headless --convert-to jpg --outdir ... file.docx

Is there a way of passing more parameters to the convert-to ? What parameters are available ?

Any help is appreciated.
Thank you,

Thank you, but my question is not about how to save files and file formats.
To be clear : I need to CONVERT files using the command line. Files need to be converted as they are.
