Sumatra PDF 64-bit is a free open-source PDF reader that can also work with many other ebook, text, and comic book archive files (Mobi, ePub, DjV, CHM, XPS, CBR, and CBZ).



This lightweight and fast reader was created for maximum comfort and useful features, especially targeting users who have either very slow computers that are struggling whenever users start up an official PDF viewing application, Adobe Reader, or to enable users with small technical knowledge to easily get access to all the tools that are needed for reading PDFs.

Overview

Sumatra PDF is a free, open-source PDF reader that focuses on simplicity and efficiency. Developed by Krzysztof Kowalczyk, this lightweight software has gained popularity due to its fast performance and minimal system resource requirements.

Sumatra PDF is compatible with Windows operating systems and is designed to provide a clutter-free reading experience without compromising essential features.

Some of its most notable features are the ability to be used as a portable application that is housed on an external storage device (no installation required), PDF editing and saving, printing, over 69 language translations, and more. Download Sumatra PDF Offline Installer Setup for Windows.

As you would expect from this lightweight and very fast app, the main interface of Sumatra PDF is crafted from the ground up to be as easy to use as possible, with a minimal amount of on-screen tools being available on the top of the app (Search, Print, go to Page, next page, previous page, few modes of rendering pages, zoom, and keyword Find).

There are no complicated tools, no ways of confusing users, and even the context-sensitive properties menu of the app offers just basic controls that can be easily managed by anyone. The customization screen of the app offers minimal tools for setting the automatic zoom level, default layout, and nothing more. All in all, Sumatra PDF 64-bit is a perfect PDF viewing app for beginners and users with slow PC configurations.

- include manual (F1 to launch browser with documentation)

add ability to provide arguments to some commands when creating bindings in Shortcuts:
- CmdCreateAnnot* commands take a color argument, openedit to automatically open edit annotations window when creating an annotation, copytoclipboard to copy selection to clipboard and setcontent to set contents of annotation to selection
- CmdScrollDown, CmdScrollUp : integer argument, how many lines to scroll

- bug fix: Del should not delete an annotation if editing content
- bug fix: re-enable tree view full row select
- change: CmdCreateAnnotHighlight etc. no longer copies selection to clipboard by default. To get that behavior back, you can use copytoclipboard argument instead.
- change: Ctrl + Tab is now CmdNextTabSmart, was CmdNextTab. Ctrl + Shift + Tab is now CmdPrevTabSmart, was CmdPrevTab. You can re-bind it if you prefer old behavior
- CmdCommandPalette takes optional mode argument: @ for tab selection, # for selecting from file history and > for commands.
- command palette no longer shows combined tabs/file history/commands. CmdCommandPalette only shows commands. Because of that removed CmdCommandPaletteNoFiles because now `CmdCommandPalette behaves like it

- Ctrl + Shift + K no longer active, use Ctrl + K. You can restore this shortcut by binding it to CmdCommandPalette > command.
- add Name field for shortcuts. If given, the command will show up in Command Palette (Ctrl + K)

- swapped key bindings: i is now CmdTogglePageInfo, I is CmdInvertColors. Several people were confused by accidentally typing i to invert colors, is less likely to type it accidentally
- allow creating custom themes in advanced settings in Themes section. See docs.
