Since it’s portable, you can run it directly from a USB stick no installation required. While it skips advanced features like editing or annotation, it does the basics very well: bookmarks, search, and smooth navigation. Being open-source means it’s updated regularly and stays secure. Sumatra is a no-fuss option if you just want speed and simplicity.
