WYSIWYG e-book editor for the ePub format.


Sigil is a multi-platform WYSIWYG ebook editor. It is designed to edit books in ePub format.

  • Free and open source software under GPLv3
  • Multi-platform: runs on Windows, Linux and Mac
  • Full Unicode support: everything you see in Sigil is in UTF-16
  • Full EPUB spec support
  • WYSIWYG editing
  • Multiple Views: Book View, Code View and Split View
  • Metadata editor with full support for all possible metadata entries (more than 200) with full descriptions for each
  • Table Of Contents editor
  • Multi-level TOC support
  • Book View fully supports the display of any XHTML document possible under the OPS spec
  • SVG support
  • Basic XPGT support
  • Advanced automatic conversion of all imported documents to Unicode
  • Currently imports TXT, HTML and EPUB files; more will be added with time
  • Currently exports EPUB and SGF (Sigil native format); more will be added with time
  • Embedded HTML Tidy; all imported documents are thoroughly cleaned; changing views cleans the document so no matter how much you screw up your code, it will fix it (usually)
  • An actually usable user interface
  • Native C++ application

What's new in Sigil

Version 0.9.18:
Bug Fixes:
  • Fix bug in macOS that caused spurious warnings about missing file in the manifest
  • Hopefully fix macOS bug about launching files using open-with from Desktop
  • Make sure JQuery gets loaded before starting to use Preview javascript functions
  • Fix local links during split that incorrectly used target filename for internal link
  • Create GetEnvironmentVar to make access to environment variables more cross-platform
  • Fix macOS bug when hitting close on the title bar of MainWindow causing strange window behaviour
  • Hopefully fix macOS segfault on close by disabling Preview timer immediately
  • Fix Windows 7 issues when running batch (.bat) files via OpenExternally (open with)
  • All error messages are now properly logged
  • Fix improperly disabled open-with menu in Image Tabs popup context menu
  • Removed use of Qt obsolete methods in About and Error Dialogs
New Features
  • Enable use of SIGIL_DEBUG_LOGFILE environment var to control saving debug output to a file
  • Properly update the ncx after merging xhtml files
  • Properly warn users if a multiple rendition epub (multiple OPF files) has been loaded
  • Make Sigil's external XHtml editor work to pass an OPF file (see PageEdit new features)
  • Allow epub3 metadata editor to edit primary meta tags
  • Replace buggy cssutils module used in plugins with our own drop-in replacement fork: css-parser
  • Updated Mac, Windows, and Linux build documentation

Note: Be aware that Sigil-0.9.18 no longer enforces the need for epub3 to have and support an NCX for the purposes of backward compatibility with epub2 reading systems. There are, however, built-in tools to allow users to add backward compatibility features such as the NCX to their epub3.

Why does this application put a hidden folder named .Sigil in the Home directory? I've downloaded version 0.2.3 from the developer site.

I have used this app only once when Amazon was refusing my book in Calibre's mobi format and it saved my life. :-) I opened with Sigil the epub generated by Calibre and generated the TOC (Tools/Toc/Generate at that time) then I opened the edited epub in Kindle Previewer or kindlegen and converted to mobi. So 5 stars for this invaluable tool!

Co se tu na MacUpdate děje? Je tady spousta neaktualizovaných aplikací, Sigil má už verzi 0.9

8.01 is out at A really nice and great application to create or edit epub. My only complaints with these last versions (8.0 and 8.01) is that you can not paste text in the Replace field using key shortcut anymore. It is not a tragedy, but it's not so comfortable activate the control-click menu every time you want paste the replace string in Search and Replace… So before to upgrade take also a backup copy of previous version if it works for you.

Great software, unfortunately no longer under active development. See: I am still using it in Mavericks. I use Calibre also, which is constantly improving as an ebook editor.
