Learn the part that a convert button cannot explain
Start with the next task
Format choice is easier when you know whether the result will be shared, edited, transcribed, or archived.
- MP3 for compatibility
- WAV for editing
- M4A for efficient AAC
- Original for no re-encoding

MP4 and MOV are containers; the audio inside may be AAC, MP3, AC-3, or something else.
- An extension is not a codec guarantee
- Stream copy preserves the codec
- Transcoding creates a new codec

A useful local tool explains where bytes go, when processing begins, and how temporary memory is released.
- No conversion upload
- Worker-based processing
- Explicit cancellation and cleanup
