I think UPDF is a very good software. The program works very well for me. The initial setup was easy.

What I enjoy about UPDF compared to Adobe Acrobat Pro is that the AI features and various app tools don't get in the way. There are no pop-up asking me if I want to summarize the document, or tips that get in the way if reading the PDF. Everything is available for use, but tucked away as to not be in the way.

I use UPDF for viewing and editing PDF files. I like the file loading speed and the fairly intuitive interface. It's a cheaper alternative to Acrobat with the same functionality. It was also important that you can buy a lifetime license with crypto.
