Frequently asked questions
Is the audio converter really free?
Yes. Every conversion runs locally in your browser with no account, no watermark and no file-size paywall.
Are my audio files uploaded anywhere?
No. Files are decoded and re-encoded in your browser memory and never sent to any server.
Which audio formats are supported?
MP3, WAV, AAC, FLAC, OGG and M4A, with configurable sample rates for high-fidelity export.
Does converting reduce audio quality?
Converting to a lossless format like WAV or FLAC preserves quality. Converting to a compressed format like MP3 trades a small amount of quality for a much smaller file.
