Convert AU to MKV
Fast, free, and secure AU to MKV conversion. No registration required.
Ready to switch from au to mkv? Drag your files into the converter and download the results immediately. AU Audio is best described as sun/unix audio format for basic audio on unix systems, primarily serving Unix system sounds, telephony and basic audio processing. MKV Video takes over where AU Audio falls short: supports virtually any audio/video codec with unlimited tracks. This conversion bridges two ecosystems: Sun Microsystems's AU Audio and Matroska.org's MKV Video. Xonvert supports batch conversion — convert multiple files at once and download them all as a ZIP.
Why Choose MKV Format for Your AU Files?
There are strong reasons to convert AU to MKV:
Quality preservation: Converting from AU Audio to MKV Video maintains excellent visual quality while reducing size.
Hardware acceleration: MKV Video benefits from hardware-accelerated decoding on most modern devices, ensuring smooth playback and rendering.
Web optimization: MKV Video is better suited for web delivery, loading faster and using less bandwidth than AU Audio.
Streaming support: MKV Video is well-suited for streaming and progressive loading, making it ideal for web and mobile delivery.
Platform requirements: Many platforms and services specifically require MKV Video format, making this conversion essential for submissions and uploads.

Conversion Quality Deep Dive
AU Audio encodes data using mathematical algorithms that preserve every data point. MKV Video similarly focuses on perceptual quality. The conversion maps between these approaches intelligently. AU Audio's known limitation — no compression options, limited metadata — is resolved when converting to MKV Video, which offers supports virtually any audio/video codec with unlimited tracks. The AU Audio source uses lossless encoding. The MKV Video output uses lossy encoding. This difference in compression approach means Xonvert carefully manages the transition to preserve maximum fidelity.
Converting AU Audio audio to MKV Video video creates a video file with a static visual (typically a black frame or waveform visualization) and your audio track. This is commonly used for uploading music to video-only platforms like YouTube, creating visualizer content, or embedding audio in video projects.
Compression trade-off: Your lossless AU source retains all original data. Converting to lossy MKV will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.

Common Questions About AU to MKV
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is AU format?▼
AU Audio is Sun/Unix audio format for basic audio on Unix systems. It is primarily used for Unix system sounds, telephony and basic audio processing. Originally for Sun Microsystems workstations
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target MKV format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
Does the conversion preserve metadata?▼
Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
Can I share the converted MKV file directly?▼
Yes. After conversion, you can download the MKV file and share it via email, messaging apps, cloud storage, or any other method you prefer.
Does converting AU to MKV change the resolution?▼
Resolution is not applicable for audio files. All content data transfers at full fidelity.
Do I need to install any software?▼
No installation required. The converter runs entirely in your web browser. No plugins, extensions or desktop apps needed.
