Key Features & Benefits
Quickly cut intros, outros, ringtones, voice notes, and more without installing heavyweight desktop software.
Private & secure
Trimming happens locally in your browser. Your audio is never uploaded to a server, so personal recordings and client work stay on your device.
Precise audio trimming
Enter exact start and end times or use the current playback position to capture the perfect segment from your track, podcast, or voice note.
Fast stream copy mode
When you keep the same output format as the input, the tool can use stream copy to trim without re-encoding, giving you much faster exports.
Flexible export formats
Save your trimmed audio as MP3, WAV, FLAC, OGG, or M4A depending on whether you prefer compatibility, quality, or smaller file sizes.
Works on any device
Use the audio trimmer on Windows, macOS, Linux, or mobile devices as long as you have a modern browser like Chrome, Firefox, Edge, or Safari.
Free with no watermarks
Trim as many files as you like with no sign-up, no subscriptions, and no watermarks added to your exported audio.
Frequently Asked Questions
