A free video converter for MP4, MKV, MOV, AVI, WMV, FLV, RealMedia, DVD VOB, camcorder MTS or almost anything else, saving it as any of 32 formats. The converting happens in this tab. Your video is never uploaded.
Each file is identified from its first bytes as soon as you add it. Once the engine is loaded it is read in full, so you see the real codecs, size and length before you convert.
MPEG-4 Part 14 on the ISO base media format. The safest choice when a file has to play anywhere.

You can still change any of them before converting.
For each target: the container it is written into, the video and sound encoders used, its file type and the first bytes that identify it. The last column fills in from the loaded engine and this browser. Click a row to pick it.
