About SumatraPDF
SumatraPDF opens PDF, EPUB, MOBI, CBZ/CBR, DjVu, XPS and CHM documents on Windows. Its small, focused interface makes it a practical reader for older PCs. Choose an installer or portable build from the project download page.
If reading individual books grows into managing a collection, Calibre adds library organization and format conversion. Compare it with SumatraPDF when you need more than a lightweight viewer.
