Stirling-PDF is a powerful locally hosted web based PDF manipulation tool using Docker and AI that allows you to perform various operations on PDF files, such as splitting merging, converting, reorganizing, adding images, rotating, compressing, and more. In this step by step guide I will show you how to install Stirling-PDF on your Asustor NAS using Docker and Dockhand.
This guide works perfectly with the latest Stirling-PDF v2.10.1 release.
