Get me PHYLIP now

Note -- you probably need the full PHYLIP package, including the source code and documents in some form, simply in order to make sure that you have the documentation, even if you do not intend to ever recompile the source code. Most Windows and MacOS users will want to use the executables for their machines and will not need to recompile the source code, but everyone will need the documentation as well. Whenever PHYLIP is packaged as a single archive, it does include the all of the source code and documentation.

The Windows executables, documents, and sources are in the form of a Zip archive. To extract it, put it in a directory by itself and right-click on the icon of the archive. You will then be given the option to unpack the archive into the many files of the package.

The Mac OS X package is distributed as a .dmg Disk Image which can be unpacked using the instructions on our installation web page. The Linux executables can easily be compiled after downloading the source code -- see the installation page here.

What to do

First note that at the bottom of this page is a link to register your copy of PHYLIP, and also a link to installation instructions. To transfer the files, click on the appropriate links below. Then register, and read the installation instructions and follow them.

1. Fetch the following:

PHYLIP's license is changing to an open-source license. It now uses a license that allows re-use in other software packages without demanding a royalty. (It does not demand that all other software in that distribution be open-source). The source code tar archive below has the new license. I have designated it as a new version, 3.698.

Linux or Unix

For Linux or Unix (or other systems that need to compile from source code):

(see below for information on how to compile these, and for information on precompiled Linux and Unix executables).


We have here the PHYLIP package for Windows, which works on all versions of Windows from Windows 3.1 to Windows 10. Executables, documentation files, and source code is included in this distribution.

PHYLIP for Windows is available here in two forms. You will need only one of these, so read carefully before downloading. If you click on one of these selections to download it, make sure your browser saves it to disk. After downloading, but before you do anything else, you should read our installation instructions. If you have a recent Windows system that is able to extract a ZIP that file, and if you can transfer a file that is about 12 megabytes in size, you will want to download this zip archive, and then right-click on it to see an option to unzip the archive.

Mac OS

For Macintosh Mac OS (either Intel iMac or PowerMac) the package is distributed as a single compressed disk image (.DMG) file of 12 Megabytes. Click on this link to download it:

Documentation, source code and executables

After PHYLIP is installed, the most recent Mac OS X operating system versions, from Mountain Lion on, may refuse to run its executables when you click on the program icon. There is a good workaround for this -- see the discussion at our installation web page.

2. Register your copy
Register here after you have transferred anything

(It is not necessary to register separately for each file transferred -- you can register once after downloading several files).

3. Install PHYLIP
Here you will find more information about how to install PHYLIP on your computer once you have fetched the appropriate archive files.


Precompiled executables available elsewhere

Debian linux executables

Andreas Tille and Manuel Prinz have compiled and made available a set of PHYLIP 3.695 executables for Debian Linux. These are in the "unstable" section of Debian packages and may be downloaded for free ("free in the sense of free beer") from its page on the Debian web site at or from various Debian mirror sites. Of course, one can also install the source code (see under Unix above) and compile it yourself.

Executables for FreeBSD

A PHYLIP 3.695 package for FreeBSD Unix is available, thanks to David Bader and others. It is located at the BSD PHYLIP package web page at

Specialized source code versions available elsewhere

Source distribution for NetBSD

A set of sources and executables for PHYLIP 3.69 for the NetBSD operating system has been produced (originally by Marc Baudoin). They are available from The NetBSD Packages Collection PHYLIP page at
