Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
WebM is efficient for the web but is not accepted everywhere. iPhones, iMovie, and many social uploaders expect MP4, so converting once removes the compatibility problem. Everything runs in your browser, so the file is never uploaded to a server.
Short answers for the questions people usually have before trying a utility like this.
Yes. It is a free online WebM to MP4 converter that runs in your browser with no signup.
No. The conversion happens locally in your browser, so the video never leaves your device.
Yes. The audio track is carried over into the MP4 export.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
