How to Use the Audio Converter Online
Audio Converter changes a sound file between MP3, WAV, M4A, OGG and FLAC, one file or a batch. You set the bitrate and channels yourself rather than picking from a vague quality preset, and decoding uses the browser's own audio engine, so what you hear in the player is what gets converted. One rule to remember: turning a lossy MP3 into WAV or FLAC does not bring back anything the MP3 lost.
Converts between MP3, WAV, M4A, OGG and FLAC in the browser. The one rule worth carrying: converting a lossy file to a lossless one does not restore anything. An MP3 turned into WAV is a larger file containing exactly the same audio, minus nothing and plus nothing.

Tips and Good to Know
-
MP3 to WAV makes a much larger file with identical sound. Do it only when a program refuses MP3, not for quality.
-
Converting between two lossy formats, say MP3 to OGG, loses a little more each time. Convert from the original recording where you still have it.
-
Video files are not accepted here. Pull the soundtrack out first with Video to MP3.
Frequently Asked Questions
Answers to common questions about this tool.
Will converting MP3 to WAV improve the quality?
No. WAV is uncompressed, so the file becomes much larger, but the detail that MP3 discarded is gone and cannot be restored by changing container. Convert to WAV when a program demands that format, not to recover quality.
Which format do I need for my recording software?
WAV or FLAC for editing, because both are lossless and survive repeated saves. MP3 or AAC for listening and sharing, where the size matters more than the last few percent of fidelity.
Will Audio Converter lower the sound quality?
Cutting and joining keep the sound as it was. Converting to a smaller format such as MP3, or compressing, removes detail most people cannot hear, and a higher bitrate keeps more of it.
Does my recording get uploaded?
No. The audio file is processed right here in the tab, on the phone or computer you are using. Voice notes, interviews and private recordings stay with you, and nothing is kept once you close the page.
Which audio formats does Audio Converter accept?
Common formats such as MP3, WAV, M4A, OGG and FLAC work in most tools, depending on what your browser can decode. If a file will not open, convert it to MP3 or WAV first with Audio Converter.
How long a recording can I edit?
Songs, lectures and podcasts of ordinary length work fine. Very long recordings need more memory, so an older phone can struggle with them, and a computer with more memory copes with longer files.
Does Audio Converter work on Android and iPhone?
Yes, in any modern mobile browser. Choose the recording from your phone’s storage, make your changes and download the result. Some phones take a little longer with big files.
