Frequently Asked Questions
- What audio formats are supported?
- You can convert between MP3, WAV, OGG, AAC, FLAC, M4A, WMA, and OPUS formats. All common audio formats used on the web, mobile devices, and music players are supported.
- Is this audio converter really free?
- Yes, completely free with no limits, no signup, and no quality loss. The conversion runs entirely in your browser using FFmpeg.wasm, so there are no server costs.
- Are my audio files uploaded to a server?
- No. All conversion happens locally in your browser. Your audio files never leave your device — we have zero access to your files. This is the most private way to convert audio online.
- What quality settings are used?
- MP3 and AAC output at 192kbps for high quality. FLAC and WAV are lossless — no quality degradation at all. OGG outputs at 192kbps with Vorbis encoding.
- Can I convert multiple audio files at once?
- Yes! Drag and drop or select multiple files at once. All files will be converted to your chosen output format and can be downloaded individually or all at once.
- How does browser-based audio conversion work?
- We use FFmpeg compiled to WebAssembly, which runs entirely in your browser. The first conversion loads a ~30MB engine, then subsequent conversions are fast. Audio files typically convert in seconds.
