Frequently Asked Questions
No. Thanks to WebAssembly and Web Audio APIs, all transcoding happens directly in your browser. Your audio never touches our server.
You can convert between MP3, WAV (lossless), OGG (Vorbis), and AAC/M4A with custom bitrate controls from 128 kbps to 320 kbps.
Since conversion runs in your local browser memory, you can convert standard music files, podcasts, and recordings without server upload limits.
