Sumatra PDF in Windows - a free compact fast open-source program. Serves for visualization, viewing, printing of documents in PDF, FB2, DjVu, ePub, CBR/CBZ, CHM, MOBI, XPS formats. The program has an optimal design, is fast in operation and compact. It is created based on the MuPDF engine.
An unusual feature — you can edit PDF files opened in Sumatra using another program (the Sumatra file does not lock). The program processes documents several times faster than Adobe Reader, consuming few system resources. Unlike other programs - Sumatra PDF correctly scales, smoothing black-and-white images (scanned books, but not recognized).
The program has an installer, but a portable version also exists, it works from an external USB card without installation. The program can be set as the default PDF viewer, then they will automatically open in this program. Hotkey support makes working with the program even more convenient and faster.
Main functionality:
- Viewing PDF files is done via menu or by dragging into the program window.
- Hotkeys for quick navigation through documents.
- Setting as default PDF viewer.
- Zooming pages.
- Copy option.
- Support for SyncTeX - a two-way synchronization method of source TeX documents and PDF output, which are obtained using XeTeX and pdfTeX.
- Printing is done by converting all pages to a raster image, which increases the data volume and slows printing on printers with little memory.
Changes in the latest version:
- Ctrl-L – switch to full-screen e-book viewing mode.
- New keyboard commands.
- Supports WebP images.
- Supports RAR5 format comics.
- Fixed bugs.
