  1. Mac users should still download and install ActiveState's ActiveTcl Community Edition to utilize plugins that use Tk/Tcl GUIs. Mac users should also check out the wiki entry on the New Release File Format. The latest Sigil user guide can always be downloaded from its own repository. PGP Fingerprint.
  2. Jul 25, 2020 Download Sigil. Sigil is a multi-platform EPUB ebook editor with the following features.

Sigil is a multi-platform WYSIWYG ebook editor. It is designed to edit books in ePub format. It is free and open source software under GPLv3, It provide full Unicode support: everything you see in.

Binaries (Installers)

Binary packages are available under releases at the main code hosting location. The latest release will be on top. You can see what’s changed between releases by looking at the ChangeLog.

Note that currently Sigil only provides binaries that work for Windows x86 and x64 and will only run on Vista or newer releases. Mac OS X binaries are typically 1 version behind the current release. This means that today 10.10 is the current release so it should run on the 10.9 (with the latest updates installed). However, this is subject to change and this information is not always current. Especially for OS X. This is an at best support for older versions of Windows and OS X.

All releases also have CHECKSUM.sha256 file which includes sha256 check sums of the file posted. This will let you know if you have a bad download or if a build has been tampered with.

Going forward release announcements will include the sha256 checksum of the checksum file itself so you can verify that it hasn’t been tampered with either.

Finally, the OS X .app file (not the .dmg) is signed before release. You can use the code sign command line tool (I don’t know of another way) to verify the application. There will be a lot of output but you’re looking for my signature saying I (Kevin, the project maintainer built this binary). From a terminal run:

There will be a lot of output but you should look for the following: Authority=Developer ID Application: Kevin Hendricks (2SMCVQU3CJ)

Issue Tracker

The issue tracker is for development issues that are actively being worked. It is not a user support system. It is meant solely for development and for developer to developer communication. If you need help then head over to the Support Page.


Feature requests opened on the issue tracker will be closed if there isn’t anyone willing to implement the requested feature. Only items being worked will be left open.

Sigil On Linux

Sigil will run on Linux. We try to maintain compatibility with Linux mainly because it’s easy to with Sigil supporting both OS X and Windows and it uses a number of technologies that already support Linux. That said, there is currently no official Sigil binary package for Linux.

If you’re looking to use Sigil on Linux, you can always build it from source. The docs directory in Sigil’s Github repository has instructions that can guide you in that endeavor. You can also look to see if Sigil is available in the official repositories for your flavor of Linux.

What's New:

Sigil-1.3.0 represents a mix of bug fixes and new features for both epub2 and epub3 users.

Windows users please note that the installer will now allow Sigil to be installed for the current user only if desired. The installation of the included Visual Studio C++ runtime, however, will always require administrative privileges. You can provide those credentials for the runtime install portion only (if you install Sigil for the current user). The user can also skip the runtime check/install entirely if they desire. If they do so, however, it will be up to them (or their administrator) to make sure the proper Visual Studio C++ runtime is installed. Because of these changes, it recommended that Windows users uninstall the previous version of Sigil before installing this one. No settings, preferences, or plugins (or their configurations) will be lost by doing so.

New Features (since the 1.2.0 release):

  • Added FontTab to show a specific font by double-clicking in BookBrowser
