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.

Download the trimmed clip as a WAV file (uncompressed, full quality) or an MP3 (smaller, great for sharing) — your choice. WAV export is instant; MP3 uses a small encoder that loads the first time you pick it.

Features

• Set start and end from the playhead — play or scrub, then mark each point
• Visual waveform — or drag the handles to pick the exact section
• Play the selection before you save it
• Download as WAV or MP3 — lossless quality or a smaller file
• Fine control — type the start and end as mm:ss.mmm, or set a duration
• 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
• Find the start — play or scrub the audio, then click "Set start from playhead"
• Find the end — scrub to the end point and click "Set end from playhead" (or drag the waveform handles / type the time)
• Preview it — click "Play selection" to hear just that part
• Choose WAV or MP3, click "Trim", then press Download to save the cut

Frequently asked questions

Is it really free with no watermark?

Which files can I trim?

Any audio your browser can decode, including MP3, WAV, M4A (AAC), OGG and usually FLAC.
