MP4, MKV, MOV or WebM, up to 20 files.
MP4 plays almost everywhere, but sometimes you need something else from it: the sound as MP3, a clip as a GIF, or a MOV for an editor. Other times a MOV or MKV needs to become MP4. Drop a file here; the conversion runs in your browser and the video stays on your device.

Questions
What can an MP4 become?
MP3 or WAV for the sound, M4A with the audio track copied as it is, MOV for editors that prefer it, or a GIF made from a short clip.
Does converting MOV or MKV to MP4 re-encode the video?
No. The video and audio streams are placed in an MP4 file unchanged, so the picture and sound are exactly what you started with.
How do I make a GIF from an MP4?
Drop the video and choose GIF. The MP4 to GIF page then lets you set the start, length, frame rate and width of the clip in Options.
Should I extract MP4 audio as M4A or MP3?
M4A keeps the original audio track without re-encoding, so nothing is lost. MP3 is encoded again with LAME but plays on more devices.
