Convert audio files in your browser. Upload MP3, WAV, WMA, OGG, M4R, 3GPP, OPUS, M4A, AAC, AMR, FLAC, AIFF, or APE files, then create a downloadable output file manually.
Drop an audio file here, or choose a file from your device. The converter tries to decode the file locally in your browser.
Supported formats
The converter accepts common audio extensions including MP3, WAV, WMA, OGG, M4R, 3GPP, OPUS, M4A, AAC, AMR, FLAC, AIFF, and APE. Because this version runs locally in the browser, real decoding support depends on the browser and operating system.
How to use
Browser limits
A browser audio converter is fast and private for formats the browser can decode and encode natively. MP3, WAV, AIFF, and some MediaRecorder formats can work without a server. Older or less browser-friendly formats such as WMA, AMR, 3GPP, APE, and guaranteed AAC/MP4 outputs may fail without server-side conversion.
This page keeps the workflow safe for AdSense and user experience: it does not auto-download files, does not claim that every browser can process every codec, and shows a clear message when a format is not supported locally.
