This page contains a collection of tools and services to simplify, make more efficient, or provide additional functionality to the work with Wikimedia Commons. Some of the tools here are optionally directly integrated within the Wikimedia Commons web interface. If you want to know how to play back and view contents of Wikimedia Commons have a look at the media help page. If you are in search for software editing and creating media files have a look at our software page. There is also a automatically generated list of commons tools on Toolforge.

Some tools have a gadget available to provide convenient access. Gadgets can be activated in your Preferences.

Tool integration[edit]

Some of the tools described here are directly integrated into the web interface of Wikimedia Commons via gadgets (notably ExtraTabs2). Gadgets can be enabled via the Gadgets tab of a user's Preferences. Tools marked with an asterisk (*) on this page have an associated gadget.

Authenticating tools (OAuth and TUSC)[edit]

There are two primary ways for authenticating externally hosted tools to use your Wikimedia Commons account:

  • More recently developed tools use MediaWiki's OAuth support to provide seamless integration and allow tools to securely take actions under your username. An example is CropTool. No separate account is required for using tools which support OAuth.
  • The Toolserver User Screening Tool (TUSC) was a community-developed legacy system that permitted many of the tools listed below to authenticate your connection to your Commons account, without requiring that you disclose your Commons password on the site. You can create a new TUSC account here: TUSC. It is recommended not to choose the same password as your Commons password. And be sure to create one for "commons" (not wikipedia) if you want to use the tools here at Commons. See also the overview on German Wikipedia (automatic machine translation to English).
