Uploads on Wikimedia Commons are normally limited to a maximum file size of 100 MiB (although files up to 1000 MiB = 1 GiB = 1048576000 bytes may be uploaded using the Upload Wizard and chunked uploading). However, system administrators have ways to circumvent this limit, and you may ask for their help if needed.


  • URL(s), publicly accessible without logins or passwords[1], to
    • the files themselves. They should already have the correct names
    • the file description page (wikitext) for each file, as a .txt file. So the description page for Foo.ogv should be in Foo.ogv.txt
  • User name to use for the upload
  • Commitment to deal with post-upload complaints. Regarding licence or file description...

Providing the files as ZIP/TAR/TGZ archives is fine (and preferred for larger numbers of files).


Please file a request on Phabricator (more information on Phabricator), where a system administrator will process your request.

Examples of past requests: phab:T33175, phab:T36771, phab:T35475, phab:T34236, phab:T33188, etc.

What to do if files represent hundred of GB to several TB?[edit]

If you prepare a mass upload of large files, for example dozens of videos from a GLAM project, and it's not technically possible to upload so much content, you can prepare a hard disk with the files, using the same procedure described above.

Once done, open a task on Phabricator, and you will be provided with the address of the datacenter to mail the disk to (don't mail the disk before you receive a confirmation with a tracking number: we need to register the delivery before it's received by the datacenter staff).

You should use Fedex, UPS or DHL as carrier. We're unable to receive USPS mail.

It will then be added to a shell machine, and processed, as URL requests are.

As this requires extra human handling, this procedure is only for when it's technically not possible to upload files through the network.

Examples of past requests: T50205 (successful), T69477 (failed) – sender denied to use recommended delivery companies.

  1. You can use Google Drive to host your files:
    1. Upload the file to Google Drive
    2. Make the file 'Public to the web'
    3. Copy the ID of the published file and append it to ***append**ID*** (The prefix turns the URL into a hotlink)
