About Media Format Converter

MediaBunny's Media Format Converter is a powerful browser-based tool that transforms your audio and video files between popular formats without requiring any software installation. Powered by the cutting-edge WebCodecs API, it delivers native-speed encoding and decoding directly in your browser, ensuring your files never leave your device for maximum privacy and security.

Our converter supports a wide range of formats including MP4 (H.264/AAC), WebM (VP9/Opus), and WAV for lossless audio. With batch processing capabilities, you can queue multiple files and convert them sequentially, saving valuable time when working with large media libraries. The intelligent format detection automatically identifies your source files and suggests optimal output settings.

Whether you need to convert videos for web compatibility, extract audio tracks from video files, or prepare media for specific platforms, our converter provides granular control over quality settings, bitrates, and codec parameters. The real-time progress indicator keeps you informed throughout the conversion process, and all processing happens locally on your machine.
