How the Audio Converter Works
This free audio converter uses the same professional FFmpeg engine used in studio software, compiled to WebAssembly. Your files are processed directly in your browser, so your recordings never leave your device.
1. Upload your audio file
Drag and drop an audio file into the upload box or click the button to browse from your device. The tool will read the file, estimate its size and duration, and show a quick preview when possible.
2. Choose output format & quality
Select the target audio format (MP3, WAV, OGG, M4A, FLAC, AAC), adjust bitrate, sample rate, and channels, and decide whether you prefer lossless quality or smaller file size.
3. Convert and download instantly
Click Convert Audio to start processing. Once the conversion finishes, you can play the result in your browser (if supported) and download the new file without any watermark or registration.
Key Features & Benefits
Convert audio between popular formats for podcasts, music, voice-overs, ringtones, and online content without installing any software.
100% private
Audio files are never uploaded to a server. All conversion steps happen inside your own browser, which keeps sensitive recordings and client work fully confidential.

Cross-platform & mobile
Use the converter on Windows, macOS, Linux, Android, or iOS in any modern browser such as Chrome, Firefox, Edge, or Safari.
Free with no limits
There are no watermarks, trial periods, or conversion limits. You can convert as many audio files as you want, whenever you need them.
Frequently Asked Questions
Answers to common questions about converting audio files in your browser.
No. All conversions are performed locally in your browser using WebAssembly. Neither the original nor the converted files are sent to any server.
You can upload popular audio formats such as MP3, WAV, OGG, M4A, FLAC, and AAC, then convert them to MP3, WAV, OGG, M4A, AAC, or FLAC depending on your needs.
Changing formats or reducing bitrate can affect quality. Lossless formats like WAV and FLAC preserve every detail, while MP3, AAC, and OGG use lossy compression. For most uses, 192 6256 kbps is a good balance between quality and size.
Yes. The converter works on most modern mobile browsers. For large files, using a recent device and closing other heavy apps will help avoid memory limits.
There are no artificial limits on how many files you can convert. The main constraint is your device memory and browser capabilities when handling very large audio files.
No installation or account is required. Open this page in your browser, upload an audio file, choose the format you need, and download the converted result.
