Trim Audio

About this tool

This free tool trims an audio file — you see its waveform, drag two handles to select the part you want, and download just that section. It's great for cutting a ringtone, grabbing a quote from a podcast, removing silence, or shortening a voice memo.

Everything runs 100% in your browser. Your audio is decoded and cut on your own device with the Web Audio API and never uploaded to a server — so it's private, with no file-size limit imposed by an upload.

The trimmed clip is saved as a WAV file, which plays everywhere and keeps full quality. Because there's no engine to download, trimming is instant.

Features

• Visual waveform — drag the handles to pick the exact section
• Play the selection before you save it
• Fine control — type the start and end in seconds
• MP3, WAV, M4A, OGG and FLAC input
• Private — your audio never leaves your device, no sign-up, no watermark

How to use it

• Upload an audio file — click the box or drag a file in
• Select the section — drag the start and end handles on the waveform (or type the seconds)
• Preview it — click "Play selection" to hear just that part
• Click "Trim & download" to save the cut as a WAV file
