    Comments about SumatraPDF as an Alternative to Adobe Acrobat Reader
    Comment summary: SumatraPDF is praised for being lightweight, fast, and efficient, with a straightforward, clutter-free interface. It's seen as a great alternative to Adobe Acrobat Reader due to its minimal system resource usage, lack of bloatware, and open-source nature. However, users note that it lacks certain features such as annotations, editing forms, and printing in a booklet format. Users highlight its speed and ability to run from a USB drive, but remark that its user interface is dated.

    It's nowhere as vulnerable to attacks as Adobe Reader, doesn't execute embedded JS, and renders documents blazingly fast

    No bloat. Open source. Just read PDFs like the static documents they are meant to be.

    It's a good alternative to Acrobat Reader. But it doesn't have any PDF editing features. You can't rotate images either.

    It doesn't have several major features that adobe reader has. MuPDF just open files that's all. no options at all, no resizing, no editing, no change in view, there is nothing.

    If reading PDFs is all you need, this app is just wonderful. No editing tools or other bloat.
