Is my audio uploaded to a server?

No. The entire process runs in your browser on your own device, so your audio is never uploaded.

Which formats can I trim?

You can load MP3, WAV, M4A, AAC, and OGG files, as well as the audio inside many video files. The output is MP3 or WAV.

Can I trim the audio from a video?

Yes. If your browser can decode the video's audio track, you can trim it and export just the sound as MP3 or WAV.

Will trimming reduce audio quality?

WAV export is lossless. MP3 export uses lossy compression, so you'll get typical MP3 quality at the chosen bitrate.

Is there a file-size limit?

There is no upload limit because nothing is uploaded. Very long files depend on your device's available memory.

Do I need to install anything or sign up?

No. It runs in any modern browser with no installation, no account, and no watermark.

Does it work on mobile?

Yes, it works in modern mobile browsers, though very long files process faster on a desktop.

Your audio stays private

Trimming happens directly in your browser using the Web Audio API. Your file is decoded, cut, and re-encoded on your own device and is never uploaded to any server. We collect only anonymous, aggregated usage statistics (such as how often a trim starts or succeeds) to improve the tool — never your audio, filenames, or any personal data.

Verify it yourself: Open your browser DevTools → Network tab and run the tool: no request ever carries your file. Everything happens on your device.
