Change a song's key online to match your voice
If a song sits too high or too low for you, you don't have to strain — just transpose it. VocaLoft lets you shift pitch from −12 to +12 semitones in real time, right in your browser, so any track lands in your comfortable range.
Change the key now →How to transpose a song
- Open a track in VocaLoft from a YouTube link or an uploaded file.
- Move the pitch slider up or down in semitones until it fits your voice.
- Optionally adjust the tempo separately — pitch and speed are independent.
- Sing along, or download / save the transposed version.
Pitch and tempo are independent
Old tools sped a song up when you raised the pitch. VocaLoft keeps them separate: change key without changing tempo, or slow a song down to learn it without dropping the pitch. That makes it ideal for rehearsal and lessons.
Tips for the cleanest result
- Transpose by the smallest amount that fits your range — a few semitones is transparent.
- Pair it with the vocal remover to sing the lead yourself.
- Make a karaoke backing track in your key for performances.
