How we check software

Tiny, fast reader for PDF, eBook and comic files

SumatraPDF is a very small, fast document reader for Windows. It opens PDF, EPUB, MOBI, XPS, DjVu and comic book files almost instantly, and a portable version needs no installation.

It is ideal for anyone tired of slow, heavy PDF readers. It is intentionally simple: it does not offer form-heavy workflows or full annotation tools, so keep another tool for editing work.

Pros

Opens files instantly
Very small download
Portable version available

Cons

Limited annotation tools
Plain interface

Free alternative to

Adobe Acrobat Pro
