432Hz Converter: turn any song into a 432Hz file, in your browser

The 432Hz Converter is a free web tool that turns a song file (MP3, WAV, FLAC, M4A, AAC or OGG) into a 432Hz version in your browser, so nothing is uploaded. Unlike converters that change the sample rate, it keeps the exact length and tempo. A few free conversions a day; Pro adds more, longer tracks, batch mode and 24-bit WAV.

  • Nothing uploaded
  • Same length and tempo
  • MP3 or 24-bit WAV
  • Title, artist and cover kept

Free vs ProWhat is free in 432Hz Converter and what Pro adds

What makes it different

  1. Your files never leave your device

    Decoding, retuning and encoding all happen in your browser. There is no upload step, so private recordings stay private.

  2. Exactly the same length

    The converter measures the engine's delay and trims it, so the 432Hz file is exactly as long as the original and the tempo is unchanged. Some converters change the sample rate instead, which also slows the song by about 1.8%.

  3. A careful audio path

    Each file is decoded at its own sample rate (8 to 96 kHz) to avoid an extra resampling step, processed in 32-bit float, and can be saved as 16 or 24-bit WAV with Pro.

  4. Hear it before you save it

    A 15-second A/B loop from the middle of the song lets you switch between original and 432Hz as often as you like.

  5. Song details are kept

    Title, artist, album and cover art are copied to the new file, with a note that it was retuned to 432Hz.
