Audio Trimmer

Cut the part of an audio file you actually need. Load a track, drag the selection across the waveform, preview it, and export the clip as MP3 or WAV. Trimming, previewing and encoding all happen in your browser, so your audio files never leave your device.

How to trim an audio file

Add your audio

Drop an MP3, WAV, M4A or OGG file into the tool. It is decoded on your device and never uploaded.

Drag the selection

Move the region edges on the waveform, or type the exact start and end times. Play selection lets you hear the clip before exporting.

Trim and download

Pick MP3 or WAV, add a fade if you need one, then click Trim audio and download the shortened clip.

Why use Aihangsoft Audio Trimmer

See the sound

The waveform shows where the music, the silence and the speech sit, so you can cut on a beat or right before the applause.

Audio never leaves your device

Decoding, previewing and encoding all happen inside the browser tab. Nothing is uploaded, queued or stored on a server. Files never leave your device.

Exact cut, soft edges

The selection is re-encoded so it lands on the time you asked for, and the optional fade removes the click that a hard cut can leave behind.

Made for quick audio edits

Drag the region, or type the time

Pull the edges of the highlighted region with the mouse, or enter an exact start and end such as 0:12.4 and 1:03.0. Both routes update the same selection, so the numbers and the waveform never disagree.

Use case: ringtones, samples, podcast clips

Play selection

Playback starts at the selection start and stops at the selection end, so you can check the loop, the intro or the punchline without exporting first.

Use case: checking a cut before saving

Fade in and fade out

Add up to five seconds of fade at each end of the clip. The fade length is capped at half of the selection, so even a short clip keeps a clean shape.

Use case: ringtones, sleepy playlists, voice intros

MP3 or WAV output

Save the clip as MP3 at 192 kbps for sharing, or as uncompressed WAV when the clip goes back into an editor and will be processed again.

Use case: sharing, editing, archiving

Audio trimming FAQ

Yes. The waveform is drawn and the cut is encoded inside your browser, so your audio never leaves your device. There is no sign-up, no length limit and no fee, and the exported file carries no watermark.
Drag the edges of the highlighted region on the waveform to move the start and end points, or type the exact times into the start and end fields. Both controls stay in sync, and the selection is what gets exported.
Yes, because the tool re-encodes the selection instead of copying compressed frames. Stream copy on MP3 can only cut on frame boundaries and often misses the requested time by a fraction of a second, so a fresh encode is used by default.
Yes. Set the fade length slider to any value up to 5 seconds and the exported clip fades in from silence at the start and back down at the end. The fade is clamped to half of the selection, so short clips stay intact.
MP3, WAV, M4A, AAC, OGG, FLAC and Opus files can be opened, and the trimmed result can be saved as MP3 or WAV. MP3 keeps the file small, WAV keeps it uncompressed for further editing.
The selection is re-encoded, so a lossy source is encoded one more time. At the default 192 kbps that difference is very hard to hear. Choose WAV output if you plan to edit the clip again later.
