Upload the MP4 file and the converter demuxes the audio stream from the MP4 container, then transcodes it into MP2. Video frames are discarded — no second video pass, no quality loss beyond what the MP2 codec itself introduces.
By default stream 0 (the first audio track, usually the main mix). If your MP4 carries commentary, dubs, or descriptive audio on additional tracks, the advanced "audio stream" picker lets you pick 1, 2, 3... explicitly. The track list is shown in the upload preview so you do not pick blind.

If the MP2 format is lossless (WAV, FLAC, ALAC), every original sample is preserved. If MP2 is lossy (MP3, AAC, OGG, Opus), the codec recompresses — at 192 kbps the difference is inaudible for most content; at 96 kbps you may hear cymbals or sibilants softening. The MP4 container has no influence on this — only the codec settings matter.
By default yes — 48 kHz MP4 audio becomes 48 kHz MP2 audio, 44.1 kHz becomes 44.1 kHz. If you need to downsample for compatibility (e.g. 96 kHz studio masters to 44.1 kHz CD-quality MP2) the sample-rate dropdown does this with high-quality resampling.
Yes — drop a folder of MP4 files into the upload zone and we run extraction in parallel. Premium gets more parallel workers; on a 100-file batch (typical music-video collection) this is the difference between 90 seconds and 8 minutes.
Audio demux + transcode runs much faster than video re-encoding — typically 5-15% of source duration. A 1-hour MP4 -> MP2 finishes in 3-9 minutes on the standard pipeline. If the MP2 codec matches the source codec already in the MP4 (common for AAC inside MKV / MP4), it is a pure remux and runs in seconds.

Yes — same privacy model as every conversion. Source MP4 and output MP2 are processed in isolated workers and deleted within minutes. We never play, store, or share content. See /privacy/.
Almost always a stream-index mismatch — your MP4 had a multi-track audio layout and we extracted the wrong stream (e.g. the silent descriptive audio track instead of the main mix). Re-run with the advanced "audio stream" option set to the right index, or pick "all streams" to extract every track as a separate MP2 file.

MP3 plays universally. AAC / M4A plays on Apple and most Android, including factory car stereos from 2014+. OGG / Opus needs a recent player and may not work in older infotainment systems. The advanced device-target dropdown picks the safest MP2 codec for the target you select.
