About the Audio Converter
The Audio Converter is a free, client-side tool that converts audio files between the most common formats — MP3, WAV, and MPEG — directly in your browser. Whether you need to convert a WAV to MP3 for smaller file size, or an MP3 to WAV for lossless editing, this tool handles it instantly without uploading your file to any server. It uses the Web Audio API and the browser's native MediaRecorder to process audio locally.
Multi-Format Conversion
Convert between MP3, WAV, and MPEG with a single click. Choose your output format from the dropdown and download immediately.
Fully Private
Your audio file is decoded and re-encoded entirely in your browser. No data is sent to any server at any point.
No File Size Limits
Because processing happens locally, there are no server-imposed file size restrictions. Convert files of any length or size.

FAQ
Frequently Asked Questions
What audio formats can I convert between?
The Audio Converter supports conversion between MP3, WAV, and MPEG audio formats. These are the three most commonly used formats in music production and distribution.
Is there a file size limit for audio conversion?
No. Because all processing happens in your browser rather than on a server, there is no server-imposed file size limit. Very large files may take longer to process depending on your device's speed.
Will converting from MP3 to WAV improve the audio quality?
No. Converting a compressed format like MP3 to WAV does not recover lost audio data. The WAV file will be larger in size but will sound identical to the original MP3. If you need the best quality, always work from the highest-resolution source file available.
Why would I convert WAV to MP3?
WAV files are large and uncompressed, making them less practical for sharing or uploading to platforms. MP3 is a compressed format that significantly reduces file size while maintaining acceptable audio quality for most streaming and playback use cases.
Is my audio file uploaded to a server during conversion?
No. The entire conversion process runs in your browser using the Web Audio API. Your file never leaves your device.
Can I batch convert multiple audio files?
Currently the tool processes one file at a time. Drop your file, choose the output format, and download the result before converting the next file.
