About

What it does

Cutting audio is a small job that shouldn't need editing software: trimming silence from a recording, making a ringtone, extracting one answer from an interview, or shortening a music clip for a video.

This trimmer draws a waveform so you can see where the sound is, lets you drag start and end markers, preview the selection with optional fades, and export the clip as WAV (instant, full quality) or MP3.

Supported formats

Input
Anything your browser can play: MP3, WAV, OGG, FLAC, M4A/AAC and more, up to 200 MB.

Settings explained

Start / End
Type times like 1:05.5 for precision, or drag on the waveform. The clip length updates as you go.
Fades
Smoothly ramps the volume up at the start or down at the end, avoiding clicks and abrupt cuts.
Export format
WAV is lossless and instant. MP3 (192 kbps) is much smaller and uses the in-browser converter.

Good for

  • Making a ringtone or notification sound
  • Removing silence or mistakes from the start and end of a recording
  • Clipping a quote from an interview or podcast
  • Preparing a short music bed for a video

Questions, answered

Can I download or convert YouTube videos?
No. This tool only converts files already on your device that you have the right to use. It doesn't download from websites, and it can't process copy-protected (DRM) media.
Why is my WAV file so large?
WAV is uncompressed, about 10 MB per minute of stereo audio. Choose MP3 for a much smaller file.
Does trimming reduce quality?
WAV export keeps full decoded quality. MP3 export re-encodes at 192 kbps, which is transparent for most listening.
Are my recordings uploaded?
No. Audio is decoded, trimmed and encoded in your browser.
