Comparison of Mupdf and Other PDF Rendering Libraries - xiangxw/mupdf-qt GitHub Wiki

Other poppler PDF rendering libraries are: Foxit, Adobe Reader and Poppler. Almost all of the PDF readers on Linux use Poppler library. Poppler is open source. While the other two are not.

• The best rendering quality(absolutely better than Foxit and Poppler, even better than Adobe Reader).
• The fastest and smallest(absolutely faster and smaller than Adobe Reader and Poppler, even faster and smaller than Foxit), so it's often used on embedded system. But of cource works quite well on PC too.
• Good cross-platform support.
• Good CJK support(CJK support of Poppler is really poor).
