This is a summary of the full project scope policy.

Wikimedia Commons (this site) is a repository of free, educational media files used by Wikipedia, other Wikimedia projects, and others. The free part is very important – it's a founding principle of Commons that we should only host content that can be used by anyone for any purpose.

Commons does not host fair use content or other non-free content, such as most content published on the Internet and elsewhere. Commons does not host encyclopedic articles or other non-media content. We also don't host content unless it has educational value.

For a file to be welcome on Wikimedia Commons it must meet the following criteria:

Must be freely licensed or public domain

It's a founding principle of Commons that we should only host content that can be freely used by anyone for any purpose. Therefore, Commons can only accept two types of content:

  1. Content whose copyright holder has explicitly agreed to allow anyone to use it for any purpose
  2. Content that is not protected by copyright

Recently created works such as photos, drawings and videos are almost always protected by copyright – even if there is no copyright notice. Copyright protection means that the copyright holder has the right to specify who may use the work and how they may use it. One way to specify this is by using a copyright license. Only the copyright holder can grant a license. The copyright holder is usually the person who created the work, such as a photographer or painter. Wikimedia Commons only accepts copyrighted works if they are covered by a license that allows anyone to use them freely for any purpose.

Commonly used free licenses include Creative Commons Attribution Attribution ("by") icon and Creative Commons Attribution Share-Alike Attribution ("by") iconShare-Alike ("sa") icon without Non-Commercial Non-Commercial ("nc") icon or No-Derivatives No-Derivatives ("nd") icon restrictions, but there are also other accepted licences.

Common examples of licenses that are not accepted on Commons include all Creative Commons licenses with Non-Commercial Non-Commercial ("nc") icon or No-Derivatives No-Derivatives ("nd") icon restrictions.

Content that is not protected by copyright is said to be in the public domain. Public domain content is accepted at Commons, but you must be able to explain why the content is in the public domain. Common reasons include that the content is too simple to be protected by copyright, that the copyright expired or that the copyright holder explicitly released it into the public domain. Merely making a work accessible to the public does not mean that it is released into the public domain.

Copyrighted content without any indication of a free license is not accepted, even in the absence of a copyright notice. Content explicitly marked as non-free, including content with All Rights Reserved or fair use notices is not accepted.

Must be realistically useful for an educational purpose

Wikimedia Commons only hosts content that is useful for educational purposes. This means content that could be used by Wikipedia, other Wikimedia projects, or other projects that provide knowledge, instruction or information. Files don't have to be in use on any other project to be hosted here, but they must have a reasonable potential use.

Examples of content that is not realistically useful for educational purposes in most cases:

  • Private image collections such as private party photos, photos of yourself and your friends and holiday snapshots. A small number of personal images used on Wikimedia project user pages are allowed per user.
  • Self-created artwork without obvious educational uses
  • Files created or uploaded for purposes of vandalism or attack
  • Advertising or self-promotion
  • Low-quality content that does not add value beyond our existing coverage of the same topic

For details, see the full project scope policy.

Skal være en mediefil

Commons only hosts media files such as photographs, scanned images, diagrams, animations, audio (e.g. music or spoken word) and video clips.

Commons does not host encyclopedic articles or other plain-text content, and it does not host computer programs in any format (including executable files and source code).

Must be an allowable free file format


I øjeblikket er de følgende formater tilladt:

  • Billeder: SVG (for vektorgrafik), PNG (format med komprimering uden tab af kvalitet), JPEG (for fotografier), GIF (format med komprimering uden tab af kvalitet, dog er PNG foretrukken), TIFF (format med komprimering uden tab af kvalitet, dog er PNG foretrukken) og XCF (tillader brug af lag og tekst).
  • Lyd: Ogg (med komprimeringsformaterne FLAC, Speex, Opus eller Vorbis) (nyere programmer bruger filendelsen .oga i stedet for .ogg for lydklip, men .ogg kan også stadig bruges) eller MIDI.
  • Video: WebM med VP8-komprimering (og Vorbis til lydsporet) eller Ogg med Theora-komprimering (sædvanligvis med Vorbis til lydsporet). (Nyere programmer bruger filendelsen .ogv i stedet for .ogg til video, men .ogg kan også stadig bruges) - Help:Converting video.
  • Indskannede dokumenter: PDF og DjVu.

Slået fra i øjeblikket

Selvom både SXW, SWC, SXD og SXI (OpenOffice.org 1.x) såvelsom ODT, ODS, ODG og ODP (OpenDocument) teoretisk kan tillades under de samme betingelser som Commons:Scope#PDF-_og_DjVu-formaterne, er disse formater for tiden slået fra, da vi i øjeblikket ikke kan forhindre folk i at gemme skadeligt eller på anden vis ikke tilladt indhold inden i OpenOffices ZIP-baserede filformat.

For a longer list of unsupported file types, see Commons:File types (Unsupported file types).
