Frequently asked questions
Are my audio files uploaded?
No. Your files are read and converted inside the browser. The FFmpeg WebAssembly engine itself is downloaded when you first start a conversion.
Does converting improve audio quality?
No. A converter can change format and encoding settings, but it cannot restore detail already lost in a compressed source file.
Why can conversion take a while?
Audio is processed locally with WebAssembly. Speed depends on file length, format, device performance, and the selected output settings.
Which output is best for quality?
WAV and FLAC are lossless outputs. MP3 and OGG are lossy formats and trade some audio data for smaller files.
