Hello. BentoPDF does provide a GUI for operations like the ones you mentioned. However, the main goal of Bento was to bring capabilities that traditionally only exist in backend or native tools, such as Ghostscript, qpdf, LibreOffice, PyMuPDF, and similar stacks onto the web.

Beyond that, there are many workflows that don’t translate well to a CLI at all such as drag and drop merging and organization, visual page manipulation, form creation, cropping, annotations, and text editing. These are hard to do reliably or efficiently in a terminal, and not everyone uses or is comfortable working with CLI tools.

So all the processing happens in the browser and you get a local hostable, OS agnostic tool without needing native dependencies installed on the system. Hope that somewhat clears your doubt
