Format
Output Quality

Honest quality: streaming sources are about 128 to 160 kbps. A 320 kbps MP3 adds headroom, not detail. OPUS keeps the original stream untouched.

Frequently asked questions

Which links can I convert to MP3?

YouTube, Spotify, SoundCloud, TikTok, Instagram, X, Bandcamp, Vimeo, Mixcloud, and Audiomack. Paste the link, pick MP3, WAV, or MP4, and download the result. There's no account, no ads, and no watermark.

Which MP3 bitrate should I pick?

320 kbps for the best quality, 192 for a good balance, 128 for the smallest file. Be realistic about the ceiling, though: the source is already a compressed stream, so 320 preserves what's there rather than restoring anything the platform threw away. Pick WAV if the file is going into an edit or a DAW.

Is this allowed?

Keep it to personal use: your own uploads, licensed material, or a track you already own. Downloading someone else's music to redistribute or monetize is on you, not on the tool. Most platforms' terms also cover this, so treat it as a personal-archive tool.

Does the link get sent to a server?

A pasted link has to be fetched for you, so that step doesn't happen on your device. A local audio file you drop in is different: it's converted in your browser and never leaves your machine. Either way there's nothing to sign up for.
