Why remove WEBM metadata?
WEBM containers can include comments, encoder notes, and attachments that expose tooling. Cleaning keeps streams and timing intact while removing that data.

Strip comments and encoder tags before posting WEBM assets online.
Reduce attribution trails
Remove muxer and language tags that reveal origin or workflows.
Keep animations private
Share WEBM animations without embedded comments or attachments.
Secure WEBM cleaning
We scrub WEBM tags using metadata-only operations, then delete the temporary copy after processing.
