Audio Converter
Convert audio files between MP3 and WAV. Select bitrate and channels. All processing is done locally in your browser.
How to Use Audio Converter
- Upload any audio file – the tool accepts MP3, WAV, M4A, FLAC, and any format supported by your browser’s decoder.
- Choose output format and bitrate – select MP3 (128, 192, or 320 kbps) or WAV (lossless). You can also toggle mono conversion if needed.
- Click “Convert” – the audio is decoded in your browser and re‑encoded into the target format using the LAME encoder (for MP3) or a raw PCM encoder (for WAV).
- Download the converted file – the new audio file is saved to your device immediately.
Benefits of Audio Converter
- Convert audio to MP3 for smaller file sizes and universal compatibility, or to WAV for uncompressed studio quality.
- Choose bitrate: 128 kbps for voice recordings, 192 kbps for music, 320 kbps for maximum quality.
- Mono conversion reduces file size further for podcasts and voice notes where stereo is unnecessary.
- No software installation, no upload to servers, and works on any device with a modern browser.
Frequently Asked Questions
Can I convert a large audiobook file (e.g., 4 hours long)?
Yes, but the conversion may take a minute or two depending on your device’s processing power. The tool processes the entire file in memory, so very large files (over 500 MB) may cause browser slowdowns on low‑end devices.
What is the difference between 128 kbps and 320 kbps MP3?
128 kbps gives a smaller file size and is good for voice and casual listening. 320 kbps is near‑CD quality and better for music with a lot of detail. WAV is uncompressed and lossless.
Will the metadata (artist, album, cover art) be preserved?
No. This tool converts only the audio content. Metadata and cover art are not transferred to the output file. You can add them later using a tag editor.
Is Audio Converter free and private?
Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
