Sumatra PDF 3.6 – Final

Sumatra PDF is a slim, free PDF, XPS, DjVu, PDF, ePub, MOBI, CHM, CBZ and CBR reader for Windows with a minimalistic design. Simplicity has a higher priority than a lot of features.

This reader is small and starts up very fast. Options are a little thin on the ground but the application provides a very comfortable environment for reading PDFs. And you can print documents without much hassle.

Furthermore, you can take this over Adobe Acrobat any day for looking at eBooks. Also Sumatra PDF is designed for portable use. It’s just one file with no external dependencies so you can easily run it from external USB drive. And it takes up little disk space.

Portable Edition is the lightweight app, so you can view PDF files on the go. You can place it on your USB flash drive, iPod, portable hard drive or a CD. Also you can use it on any computer, without leaving any personal information behind.

Sumatra PDF can do for you:

• open PDF files via menu
• open PDF files via drag and drop
• set different zoom levels via menu

The application does not lock the PDF file. Without closing the PDF file a user can recompile the text document and generate a new PDF file and then press the R key to refresh the PDF document. Printing is achieved in Sumatra by transforming each PDF page into a bitmap image.

This results in very large spool files and potentially slow printing on printers with little memory. Hyperlinks that are embedded in PDF documents are not active in Sumatra.

This reader is multilingual, with 20 community-contributed translations. Supports SyncTeX, a bidirectional method for synchronizing TeX source and PDF output produced by pdfTeX or XeTeX.

Changes in version 3.6 (2026-03-17):

• add DisableAntiAlias advanced setting and CmdToggleAntiAlias command
• add CmdShowAnnotations, CmdHideAnnotations, CmdToggleShowAnnotations commands for temporarily hiding / showing annotations
• add CmdToggleInverseSearch to temporarily disable mouse click invoking tex inverse search
• add bgcolor, opacity, textsize, borderWidth arguments to CmdCreateAnnot* commands
• add Annotations.FreeTextBackgroundColor and Annotations.FreeTextOpacity advanced settings
• sort thumbnails on home page by most recently used date. Set advanced setting HomePageSortByFrequentlyRead = true to revert to pre-3.6 behavior of sorting by frequency of use.
• support brotli compression in PDF files
• in Command Palette, if you start search with : we show everything (like in 3.5)
• in Command Palette, when viewing opened files history (#), you can press Delete to remove the entry from history
• improved zooming:
  • zooming with pinch touch screen gesture or with ctrl + scroll wheel now zooms around the mouse position and does continuous zoom levels. Used to zoom around top-left corner and progress fixed zoom levels shown in menu
• include manual (F1 to launch browser with documentation)
• add LazyLoading advanced setting, defaults to true. When restoring a session lazy loading delays loading a file until its tab is selected. Makes SumatraPDF startup faster.
• new commands in command palette (Ctrl + K):
  • CmdCloseAllTabs : “Close All Tabs”
  • CmdCloseTabsToTheLeft : “Close Tabs To The Left”
  • CmdDeleteFile: “Delete File”
  • CmdToggleFrequentlyRead : “Toggle Frequently Read”
  • CmdToggleLinks : “Toggle Show Links”
  • CmdInvokeInverseSearch
  • CmdMoveTabRight (Ctrl + Shift + PageUp), CmdMoveTabLeft (Ctrl + Shift + PageDown) to move tabs left / right, like in Chrome
• 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
  • CmdGoToNextPage, CmdGoToPrevPage : integer argument, how many pages to advance
  • CmdNextTabSmart, CmdPrevTabSmart (Smart Tab Switch), shortcut: Ctrl + Tab, Ctrl + Shift + Tab
• added UIFontSize advanced setting
• removed TreeFontWeightOffset advanced setting
• increase number of thumbnails on home page from 10 => 30
• add ShowLinks advanced setting and “Toggle Show Links” (CmdToggleLinks) for command palette
• default ReuseInstance setting to true
• added Key arg to ExternalViewers advanced setting (keyboard shortcut)
• added Key arg to SelectionHandlers advanced setting (keyboard shortcut)
• improved scrolling with mouse wheel and touch gestures
• theming improvements
• go back to opening settings file with default .txt editor (notepad most likely)
• don’t exit fullscreen on double-click. must double-click in upper-right corner
• when opening via double-click, if Ctrl is pressed will always open in new tab (vs. activating existing tab)
• register for handling .webp files
• 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
• removed CmdCommandPaletteOnlyTabs, replaced by CmdCommandPaletteNoFiles @
• 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)
• closing a current tab now behaves like in Chrome: selects next tab (to the right). We used to select previously active tab, but that’s unpredictable and we prefer to align SumatraPDF behavior with other popular apps.
• 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
• improve scrolling with middle click drag
• make built-in keyboard shortcuts work on non-us keyboards (cyrillic , hebrew etc.)
• add CmdDuplicateInNewTab (Open Current Document In New Tab) command
