How it works
- 1.Upload your audio file — MP3, WAV, FLAC, M4A, OGG, and more are all accepted.
- 2.BPM is detected automatically from the audio. The result appears within seconds. If detection fails, you can enter the BPM manually.
- 3.Expand the BPM Changer panel, enter your target BPM, choose your output format, and convert. The output matches your target tempo while the pitch stays the same.
What changes, what stays the same
- Changes:Speed and total duration. A 3-minute track at 120 BPM becomes approximately 2.5 minutes at 144 BPM.
- Preserved:Pitch — the musical key and tone of every instrument and voice stays identical. Nothing sounds higher or lower.
When to change the BPM
DJ & music production
Match tempo between tracks without re-pitching. Beat-match audio assets before loading into your DAW or DJ software for a seamless transition.
Workout & running music
Speed up or slow down a playlist to match your target cadence or exercise intensity without the music sounding higher or lower in key.
Transcription & learning
Slow down a recording to catch every word, learn a fast guitar or piano passage, or study a complicated rhythm without pitch distortion.
Mashups & remixes
Align the tempo of two recordings before mixing. Change one track to match another's BPM so beats land correctly in the combined output.
Quality and limits
BPM changing works best on rhythmic music with a steady beat. Quality degrades with very large tempo changes — more than tripling speed or slowing below one-third of the original will produce audible artifacts. For best results, stay within 2× in either direction. If you also want to shift the musical key, use the Key Changer alongside this tool — BPM and key shifts can be applied together in one conversion.
