Frequently asked questions

Which audio formats are supported?

MP3, M4A, AAC, FLAC, and Ogg files can be converted to WAV.

Does converting to WAV improve the audio quality?

No. The quality lost in a lossily compressed original like MP3 is not restored. This conversion is for editing workflows and equipment that require an uncompressed format.

How much larger will the file get?

Uncompressed PCM is several times larger than compressed audio. For example, the WAV can be 5-10 times larger than the original MP3.

Are album art and tags copied?

No. Only the first audio track is used; album art and original metadata are not copied into the output.

Is my audio file sent anywhere?

No. Your file never leaves your device. The conversion runs inside your browser and nothing is uploaded.
