Since I prefer using UPDF for everyday PDF tasks, I also learned how to set it as my default viewer. In this guide, I’ll walk you through everything in simple steps to make PDF management easier.

Why UPDF Ranks Above Adobe Acrobat
After learning how to remove Adobe Acrobat as default, I realized Adobe was slow, expensive, and not suitable for my workflow. Then I tried UPDF and realized both tools work well, but UPDF is simpler to manage. I could batch import multiple files at once, which improved how I handled PDF documents. UPDF costs about 1/6 of Adobe’s price and provides comparable full functionality for all PDF tasks.
Moreover, one UPDF license works across all devices, providing seamless access on my computer, tablet, and mobile phone. Since switching, I rely on UPDF regularly to manage PDFs more conveniently without the limitations I faced.
