Question 1

How do I upload a video to Wikimedia Commons?

Accepted Answer

Open clip2commons.toolforge.org, log in with your Wikimedia account, pick the video file from your device, fill the title, description and license, then click Convert & Upload. The video is converted to WebM/VP9 in your browser and uploaded to Commons. Most common formats are supported: MP4, MOV, HEVC, AVI, MKV, WebM. The tool runs entirely in the browser — there is no upload queue.

Question 2

How is clip2commons different from video2commons?

Accepted Answer

video2commons converts videos on a shared server with a limited queue, which often causes long waits and time-outs. clip2commons does the conversion in your own browser using the WebCodecs API, so there is no queue and no waiting. Trade-off: clip2commons cannot import from URLs (YouTube, archive.org), so video2commons remains the right tool for that workflow. The two complement each other.

Question 3

What file formats does clip2commons support?

Accepted Answer

Input: MP4 (H.264 and HEVC/H.265), MOV, MKV, WebM (VP8/VP9), and most other browser-decodable formats. Already-WebM/VP9 files are uploaded as-is without re-encoding (passthrough). Other formats are converted to WebM/VP9 1080p in the browser.

Question 4

Is clip2commons free?

Accepted Answer

Yes. clip2commons is free and open source. It runs on Wikimedia Toolforge and is licensed under the same terms as Wikimedia tools. Source code is on GitLab.

Question 5

Do I need an account to use clip2commons?

Accepted Answer

Yes — a Wikimedia account that is autoconfirmed (at least 4 days old with at least 10 edits) is required to upload, the same as Commons itself. Login is via Wikimedia OAuth 2.0; clip2commons does not see or store your password.
