Frequently Asked Questions
Which audio formats are supported?
We support over 20 audio formats including MP3, WAV, FLAC, OGG, AAC, M4A, WMA, AIFF, and more. Both input and output support all major formats.
Will converting affect audio quality?
Converting between lossless formats (WAV, FLAC) preserves full quality. When converting to lossy formats (MP3, AAC), you can choose the bitrate to balance quality and file size.
Can I convert multiple files at once?
Yes! You can batch convert multiple files simultaneously. Just select all the files you want to convert and they'll be processed together.
Do I need to upload my files to a server?
No! All conversion happens directly in your browser using FFmpeg WebAssembly. Your files never leave your device, ensuring complete privacy.
What bitrate should I choose?
For MP3, 320kbps is CD-quality. 256kbps is excellent for most uses. 128kbps is good for voice recordings or when file size matters. FLAC is always lossless.
