Wikimedia Commons is a media file repository making available public domain and freely-licensed educational media content (images, sound and video clips) to all.

Wikimedia Commons is a media file repository making available public domain and freely-licensed educational media content (images, sound and video clips) to everyone, in their own language. It acts as a common repository for the various projects of the Wikimedia Foundation, but you do not need to belong to one of those projects to use media hosted here. The repository is created and maintained not by paid archivists, but by volunteers. The scope of Commons is set out on the project scope pages.
Wikimedia Commons uses the same wiki-technology as Wikipedia and everyone can edit it. Unlike media files uploaded to other projects, files uploaded to Wikimedia Commons can be embedded on pages of all Wikimedia projects without the need to separately upload them there.
Wikimedia Commons is part of the non-profit, multilingual, free-content Wikimedia family.
The aim of Wikimedia Commons is to provide a media file repository:
that makes available public domain and freely-licensed educational media content to all, and that acts as a common repository for the various projects of the Wikimedia Foundation.
The expression "educational" is to be understood according to its broad meaning of "providing knowledge; instructional or informative".
