About This Online Pitch Changer
Guitar Tool Hub's free pitch changer (also called a music pitch shifter) changes the key of any song or audio file right in your browser. Upload an MP3, WAV, M4A, OGG, or FLAC, shift the pitch up or down by up to 12 semitones — keeping the original tempo — then preview the result and download it as MP3 or WAV. You can also change the speed independently of pitch to slow tricky passages down for practice. Because all processing happens locally on your device, nothing is ever uploaded.

Frequently Asked Questions
Upload your audio file to the pitch changer, drag the pitch slider up or down by the number of semitones you want to move, and press Preview to hear it. Each semitone is one half-step, so +2 semitones raises the song by a whole tone. When it sounds right, download the result as an MP3 or WAV. Everything happens in your browser.
No. The pitch changer uses a phase-vocoder algorithm that changes pitch independently of tempo, so raising or lowering the key keeps the song playing at its original speed — no chipmunk or slow-motion effect. If you also want to slow the track down, use the separate Speed control.
No. The entire process — decoding, pitch shifting, and exporting — runs locally in your browser using the Web Audio API. Your file is never sent anywhere, which keeps it private and means the tool works even on large files without an upload wait.
You can load MP3, WAV, M4A, OGG, FLAC, and most common audio files your browser can decode. You can export the shifted result as a 192 kbps MP3 or as a lossless WAV file.
Count the half-steps between your starting key and target key. For example, C to D is +2 semitones, C to F is +5, and dropping a whole step down (for easier singing) is −2. A full octave is 12 semitones.
Yes. If a song is tuned slightly sharp or flat, or you want it in a more guitar-friendly key, shift the audio until it lines up with standard tuning or your capo position, then download it to practice or jam along.
