Why convert WebM to MP4?

You'll reach for a WebM to MP4 conversion whenever the other end expects MP4 specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.

It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.

Is it private?

Privacy is the default here. Your WebM file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
