This audio converter lets you convert audio files such as MP3, FLAC, AAC, WAV, and more to other formats.
or drop, paste, or choose from cloud
MP3, WAV, FLAC, AAC, M4A, OGG, OPUS, WMA and AIFF. Convert in any direction, including from video files.
Set bitrate, sample rate and channels, or normalize the volume on export. Leave it on automatic if you prefer.
It runs in your browser on any device. Transfers are encrypted and processing is fully automated.
Upload your audio file.
Choose the format you want to convert your audio file to.
Adjust the optional settings, if available.

Lossless formats such as FLAC, WAV and ALAC keep every bit of the original recording. They are the right choice for archiving, mastering and anything you will edit again later.
Lossy formats such as MP3, AAC and OGG remove detail your ear is unlikely to notice. In exchange you get files a fraction of the size. They are the right choice for listening, sharing and uploading.
For music, 192-320 kbps keeps a lossy file close to indistinguishable from the source for most listeners on most equipment. For speech and podcasts, 96-128 kbps is usually enough and roughly halves the file size.
Variable bitrate (VBR) spends more data on complex passages and less on quiet ones. It usually gives better quality per megabyte than a fixed rate.
Going from one lossy format to another re-encodes audio that was already compressed once. MP3 to AAC is the common case. A little more detail is lost each time.
Where you still have the original lossless file, convert from that instead. Where you do not, convert at the same bitrate or higher to keep the second generation as close as possible to the first.
MP3, WAV, FLAC, AAC, M4A, OGG, OPUS, WMA, AIFF and more, in any direction. You can also convert the audio track out of a video file.
Yes. Everyday conversions are free and need no account. A subscription only adds larger files, batch processing and no waiting.
Yes. Add as many files as you need and they are converted together, each returned as its own download.
Converting to a lossless format such as FLAC or WAV keeps everything. Converting to a lossy format loses a little detail, so choose a higher bitrate to minimize it.
No. Everything runs in your browser, so it works the same on Windows, macOS, Linux, Android and iOS.
Uploads and results travel over an encrypted connection. Processing is automated with no human access, and nothing is shared with third parties.
Yes. Open the optional settings before starting to set bitrate, sample rate, channels and volume normalization.
Everything here runs in the browser, with no install and no sign-up.
