About this YouTube to MP3 Converter
YouTube to MP3 extracts just the audio track from a YouTube video and re-encodes it as an MP3 file, skipping the video stream entirely rather than downloading the full video and converting it afterward — which means faster processing and a smaller file for the same length of audio. Bitrate options typically range from 128kbps (smaller file, fine for spoken word) up to 320kbps (near-source quality, better for music).
Audio quality is capped by whatever YouTube's original upload contains; re-encoding at 320kbps doesn't add detail that wasn't in the source, it just avoids throwing additional detail away during compression. For most spoken content — podcasts, lectures, interviews — 128–192kbps is indistinguishable from higher bitrates and produces a noticeably smaller file for long recordings.
This is the tool for saving a lecture to listen to during a commute, pulling a podcast episode uploaded only as a YouTube video, or extracting a reference track without needing the visual portion at all. As with the video downloader, only public, non-age-restricted videos can be processed, and extraction happens per-request without the audio being cached or stored afterward.
Copyright still applies to whatever audio you extract — this tool separates the audio stream from the video technically, it doesn't change your rights to redistribute or reuse someone else's music or spoken content.

Does a higher bitrate improve quality beyond the original video?
No — 320kbps preserves more of the original audio during re-encoding, but it can’t add detail that wasn’t already in YouTube’s source file.
How long can the source video be?
There’s no fixed cap, but very long videos (multi-hour streams, for example) take proportionally longer to process and produce a larger MP3 file.
