MP4 converter

What is MP4?

MP4 is the default container of modern video: phones record into it, cameras export it, and every browser, TV and editing tool plays it, usually carrying H.264 video and AAC audio. Being a container, an MP4 is really a box around separate video and audio tracks, which is why useful conversions include not just other video formats but also pulling the audio track out on its own.

Common questions about MP4

What is an MP4 file?

MP4 is the most widely supported video container in the world. It usually holds H.264 or H.265 video with AAC audio, and it plays on essentially every phone, browser, TV, and editor. That near-universal compatibility is why MP4 is the default target when you want a video that just works everywhere.

How do I get the audio (MP3) out of an MP4?

Convert MP4 to MP3 and hushvert extracts the audio track and encodes it to MP3 entirely in your browser, with no upload. This is the no-upload way to pull the sound from a lecture, podcast, or screen recording. You can confirm nothing leaves your device in airplane mode or the Network tab.

Can I convert MP4 to WebM in the browser without uploading?

Yes. MP4 to WebM runs client-side on hushvert, so the video never leaves your device. WebM is the open, royalty-free web video format, useful when you want a video that streams well on the web. Because the work happens locally, it is bounded by your device rather than a server.

How do I convert MOV, MKV, AVI, or WebM into an MP4?

Producing an MP4 from another video container (MOV, MKV, AVI, WebM, or GIF) runs on hushvert's clearly-labeled server lane, because re-encoding full video is more than a browser can do reliably for larger files. Those files upload over an encrypted connection, convert, and are deleted: the input immediately after conversion, the output within about an hour. The dropzone tells you it is a server conversion before you start.

Is converting MP4 private?

It depends on the direction, and hushvert is explicit about which is which. Extracting audio (MP4 to MP3) and MP4 to WebM run entirely in your browser with no upload, and you can verify it. Converting other video formats into MP4, or MP4 to GIF, uses the labeled server lane, which uploads over an encrypted connection and deletes the files shortly after. Nothing is hidden: the converter tells you which engine a job uses before you run it.
