Frequently asked questions
Is there any quality loss during conversion?
Converting to lossless formats (WAV, FLAC) preserves full quality. Converting to MP3/OGG/OPUS may introduce a small loss, controlled by the quality setting.
Can I raise the bitrate for better quality?
Yes, pick the bitrate you need or the "High" quality level in advanced settings.
Are rarer formats like WMA or AC3 supported?
Yes, input and output formats include WMA, AC3, MP2, WavPack and more.
Is it free to use?
Yes, completely free and no sign-up needed. The tool runs entirely in your browser: the file never goes to a server, so the server spends neither CPU nor traffic — there is nothing to charge for. No watermarks, no limits on file size or count.
