The zlib license is a permissive software license which defines the terms under which the zlib software library can be distributed. It is also used by many other open-source packages. The libpng library uses a similar license, libpng license, sometimes referred interchangeably as zlib/libpng license.
The zlib license has been approved by the Free Software Foundation (FSF) as a free software license, and by the Open Source Initiative (OSI) as an open source license. It is compatible with the GNU General Public License.
