About Audio Converter
Audio Converter re-encodes a single audio file from one format to another, entirely in your
browser. Reach for it to shrink a bulky WAV down to a shareable MP3, produce a
lossless FLAC archive, make an M4A that plays cleanly on Apple
devices, or turn a track into an open OGG. It all happens on your device, with
nothing uploaded. Larger files take a little longer, and you can cancel anytime.
🔒
Private by design. Your audio is decoded and re-encoded right here in your browser — never uploaded, never seen by us. Nothing you add is ever uploaded.
Frequently Asked Questions
Which audio formats can I convert between?▼
You can convert to and from MP3, WAV, OGG, M4A, AAC and FLAC. Drop in a file in one of those formats and pick a different one to save it as.
Which format should I choose?▼
Pick MP3, OGG, AAC or M4A for small files that play almost anywhere. Choose WAV or FLAC when you want a lossless copy — but note those files are much larger.
Will converting reduce the sound quality?▼
Converting to a lossless format like WAV or FLAC keeps the quality of whatever you started with. Converting to MP3, OGG, AAC or M4A compresses the audio, which is fine for everyday listening but can't add back detail that was already lost.
Is there a limit on file size or length?▼
It handles typical songs and recordings easily. Very large or very long files take more time because everything runs on your own device, and you can cancel at any point.
Why does it take a moment the first time?▼
The first conversion gets the tool ready on your device, which can take a few seconds. After that it's quicker, and larger files naturally take a little longer to process.
Is my audio file uploaded anywhere?▼
No. Your file never leaves your device — it's converted entirely in your browser, and nothing is uploaded to any server.
