Question 1

Is converting audio safe? Will files be uploaded?

Accepted Answer

Absolutely safe. Conversion is done locally in your browser, audio files never leave your device, and are not uploaded to any server.

Question 2

Why do I have to wait for loading on first use?

Accepted Answer

On first use, the audio processing engine (about 30MB) is downloaded and cached by the browser. Subsequent uses do not require re-downloading, and it can even be used offline.

How to choose between lossless and lossy formats?

For the highest sound quality or further editing, choose WAV / FLAC (lossless); for smaller file size, daily listening or sharing, choose MP3 / M4A / Opus (lossy), and adjust bitrate as needed.

Most common audio formats are supported as input (MP3, WAV, FLAC, M4A, AAC, OGG, Opus, WMA, etc.), with output options including MP3, M4A, WAV, FLAC, Opus.
