Free Audio Trimmer

An audio trimmer cuts unwanted time from the beginning or end of a recording and saves the selected section as a new clip. This free audio trimmer decodes and exports on your device, so your recording is never uploaded to AICurate.

How it works

Trim an audio file in four steps

Choose an audio file

Select or drag in an MP3, WAV, M4A, MP4 audio, AAC, OGG, or WebM file up to 100 MB.

Set the trim points

Move the start and end controls or enter precise timestamps to define the clip you want to keep.

Preview the selection

Play only the selected range and adjust either trim point until the clip sounds right.

Download the WAV

Export the selected samples as a standard 16-bit PCM WAV file that works in common editors and players.

Tips for a clean audio cut

Preview around both boundaries so words and breaths are not clipped.
Enter seconds directly when a range slider is not precise enough.
Keep the tab open while large files decode or export.
Use a desktop editor when you need fades, effects, compression, or multitrack mixing.

Format and quality notes

Browser codec support varies, especially for M4A and AAC. Export uses uncompressed 16-bit PCM WAV, so the result can be larger than the source. Trimming does not remove noise, normalize volume, or restore quality missing from the original.

Audio trimmer FAQ

Is this audio trimmer free?

Yes. You can load, preview, trim, and download supported audio without an account or payment.

Is my audio uploaded or stored?

No. Your browser decodes the source file and creates the trimmed WAV on your device. AICurate does not receive or store the recording.

Which audio formats can I trim?

The picker accepts MP3, WAV, M4A, MP4 audio, AAC, OGG, and WebM files up to 100 MB. Actual decoding support can vary by browser and operating system.

Why does the trimmed file download as WAV?

WAV provides a reliable, high-quality browser export without sending audio to a server. WAV files are usually larger than compressed MP3 or M4A files.

Does trimming reduce audio quality?

The source is decoded and written as 16-bit PCM WAV. It avoids another lossy compression pass, although it cannot restore quality already lost in the original recording.
