About speeding up songs online
Drop an MP3 or WAV, pick a tempo between 1.0× and 3.0×, and download the result. The file never leaves your device — decoding, time-stretch and MP3 encoding all run in the browser.
Tempo changes do not affect pitch. Voices, vocals, and instruments keep their original key. Useful for dance and cardio tracks, fitting a song into a video clip, or speeding up podcasts and audiobooks.
Need a classic chipmunk effect (higher pitch + faster tempo at once)? Open the advanced pitch slider — it works independently.
When this helps
Podcasts and audiobooks
1.5-2.5× cuts more than half your listening time without losing intelligibility. Push to 3× for long lecture skims.
Dance and fitness
Match a track's tempo to your target BPM for cardio, aerobics or choreography.
Video editing
Compress a song to fit your video duration without ruining the key.
Language learning
Gradually increase native-speech speed to train listening comprehension.
Frequently asked questions
Does pitch stay the same?
Yes. The tool uses time-stretch with pitch preservation — voices sound normal, no chipmunk effect.
What's the maximum speed-up?
Up to 3× (three times faster) — the practical ceiling for podcasts and audiobooks. For music, stay within 1.5-2× to avoid audible time-stretch artifacts. Advanced controls let you combine speed with a pitch shift.
Does this work on my phone?
Yes. The tool runs in mobile browsers — Chrome on Android, Safari on iPhone. No app install required.
Is my file uploaded anywhere?
No. Decoding, tempo processing and MP3 encoding all happen locally in your browser.
What's the output format?
MP3 (128 to 320 kbps) or lossless WAV. Pick before downloading.
