Frequently Asked Questions

Everything you need to know about converting audio online.

The converter supports MP3, WAV, M4A, AAC, OGG, FLAC, OPUS, and WMA — all combinations are supported. You can convert from any of these formats to any other.

No. Your file is processed in a secure temporary location and permanently deleted as soon as you download the converted file. If you do not download within 60 minutes, the file is automatically purged. We never store, share, or analyse your audio.

Bitrate controls how much data is used per second of audio — higher means better quality and larger file size (32–320 kbps). Sample rate is the number of audio samples per second; 44100 Hz is CD quality. Channels controls mono (1 channel, smaller) or stereo (2 channels, full audio).

Completely free: no account, no credit card, no sign-up required. Just upload your audio, choose the output format, and download.

FLAC and WAV are lossless formats — they store audio without any quality loss and do not use bitrate compression. The bitrate setting is only meaningful for lossy formats like MP3, AAC, OGG, OPUS, and WMA.
