Convert a video to MP4: the format accepted almost everywhere

Upload MOV, MKV, WebM, TS or M4V and download MP4 (H.264 with AAC audio). The app decides on its own: when it can only swap the container, the conversion is fast and lossless; when it has to re-encode, it takes longer, but the result is compatible.

What this tool does not do

One video at a time.
Videos that require re-encoding (HEVC, VP9 and others) take longer, and the conversion may lose a bit of quality.
AVI, WMV, FLV and 3GP are not accepted as input.
The new file carries the “WebFaz.com” credit in the metadata (comment and artist).
