What SumatraPDF is

SumatraPDF is a free Windows application for reading PDFs, ebooks, and comics. It opens PDF, EPUB, MOBI, CBZ, CBR, DjVu, XPS, CHM, and common image formats. Its documented PDF tools include annotation editing, form filling, signing, merging, splitting, extracting, and conversion. The app also supports text-to-speech, screen readers through Windows UI Automation, and keyboard-only operation. Readers can adjust keyboard shortcuts, themes, and toolbar layout. A portable edition can run without installation, including from a USB drive. The product is listed for Windows 7, 8, 10, and 11, with 32-bit, 64-bit, and ARM64 builds. Its maker describes the program as lightweight, with minimal memory use. Documents and their names are not uploaded, while recently opened files are stored in a local settings file. With update checks enabled, the app contacts the maker’s server; official builds also send crash reports that may include fragments of the open document. SumatraPDF is free and open source, with no ads or subscription, but it is available only for Windows and has no OCR support.
