Are audio files uploaded to a server?

No. Your browser decodes, previews, renders, and downloads the audio locally.

Which format can I export?

The editor exports a standard WAV file in 16-bit or 24-bit PCM.

The file must use a format your current browser can decode. WAV, MP3, M4A, OGG, and WebM support varies by browser.

Select the useful moment, add smooth fades, set the gain, preview it, and export a clean WAV without sending your audio to a server.

Choose an audio file or drop a file here to trim it locally

Up to 100 MB and 15 minutes. Your browser must support the source format. WAV output is always available after decoding.

Choose an audio file to begin. Processing stays in this browser tab.

Set the start and end in seconds or use the range controls. The visible selection is exactly what the WAV export contains.

Short fades remove abrupt starts and ends. Use a longer fade only when the music or room tone needs a gentler transition.

This editor creates a new WAV file. It never overwrites the audio file you selected, and the original remains on your device.
