FFmpeg flags used by this tool
Quick reference for what each parameter actually does.
- -vn
- No video — drops the video stream so we only re-encode audio. Saves CPU and avoids container weirdness.
- -c:a libmp3lame
- The reference MP3 encoder (LAME). High quality, mature, and what every other tool actually uses under the hood.
- -b:a
- Audio bitrate target. 128k is fine for speech, 192k is the music sweet spot, 320k is as good as MP3 gets.
- -ar 44100
- 44.1 kHz sample rate — the CD standard, the right default for music.
- -ac 1
- Downmix to mono — halves the file size, good for podcasts and voice.

FAQ
Which preset should I pick?
High (320k) for music you care about. Standard (192k) for casual listening — most people can't tell it apart from 320k. Small (128k) for podcasts, lectures, and audiobooks where speech intelligibility matters more than fidelity.
Is MP3 better than AAC?
Technically AAC is more efficient — same perceived quality at ~30% smaller files. But MP3 plays everywhere without question. If you want AAC, Opus, or FLAC, use Extract Audio instead.
Why does my MP3 sound worse than the original?
MP3 is lossy — it discards parts of the signal the human ear is least sensitive to. At 192k+ this is rarely audible; below 128k it can be obvious, especially with cymbals and reverb tails. Use Extract Audio with FLAC for lossless.
What input formats are supported?
Anything FFmpeg reads: MP4, MOV, MKV, WebM, AVI, FLV, plus less-common containers.
Does it work on YouTube videos?
Not directly — YouTube URLs aren't accepted (terms of service). Download with yt-dlp first, then convert here.
Is this free?
Sign up for 100 free credits. A typical conversion costs 1–3 credits depending on length. No subscription, top up as you go.
