Convert AIF to AU
Fast, free, and secure AIF to AU conversion. No registration required.
If you're working with aif files that need to be in au format, Xonvert offers a fast browser-based solution. AIF Audio and AU Audio take fundamentally different approaches: AIF Audio focuses on identical to AIFF — perfect uncompressed audio quality, while AU Audio emphasizes simple format with wide Unix/Linux tool support. Both have their place. Both formats belong to the audio category, so properties transfer naturally during conversion. Conversion history is never stored. Once you close this tab, all trace of your files disappears completely.
Why Convert AIF to AU?
There are strong reasons to convert AIF to AU:
Archival needs: AU Audio is ideal for lossless archival, making it a solid choice for preserving AIF Audio content.
Regulatory compliance: Certain industries and government agencies mandate AU Audio format for official submissions and record-keeping.
Quality preservation: Converting from AIF Audio to AU Audio maintains bit-perfect quality with no data loss.
Hardware acceleration: AU Audio benefits from hardware-accelerated decoding on most modern devices, ensuring smooth playback and rendering.
Web optimization: AU Audio is better suited for web delivery, loading faster and using less bandwidth than AIF Audio.

Technical Quality Assessment
A/B testing confirms that Xonvert's AIF Audio to AU Audio output is indistinguishable from reference-quality conversions produced by leading desktop software. The WebAssembly engine uses identical codec libraries. Same format as AIFF — only the extension length differs Originally for Sun Microsystems workstations These technical characteristics influence how quality is preserved during conversion. For audio-to-audio conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both AIF Audio and AU Audio. Converting within the same category means most properties transfer naturally.
Audio conversion from AIF Audio to AU Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Both formats are lossless, guaranteeing a bit-perfect audio transfer with no quality change whatsoever. Sample rate, bit depth, and channel layout are preserved when supported by the target format.
The AIF to AU conversion applies format-appropriate algorithms to ensure maximum data fidelity. Raw PCM audio in big-endian byte order

Questions & Answers
Why is my converted AU file larger than the original AIF?▼
File size depends on compression settings and content complexity. Try the Medium quality preset for smaller output, or the file may simply contain data that resists AU compression.
What browsers are supported?▼
Chrome, Firefox, Safari and Edge (all recent versions). Any browser supporting WebAssembly will work.
Is there a watermark on converted AU files?▼
No. Free conversions produce clean output with no watermarks. Your AU file is identical to what a paid desktop tool would produce.
Will this converter work on Chromebook?▼
Yes! Chromebooks run Chrome browser, which fully supports Xonvert's WebAssembly-based conversion engine.
Will I lose quality converting AIF to AU?▼
No — AU preserves quality losslessly. Your output will be faithful to the original.
Does this tool support drag and drop?▼
Absolutely. Drag files directly from your file manager onto the converter area. You can also click to browse, or paste from clipboard.
Can I adjust conversion quality settings?▼
Yes. The settings panel lets you control output quality, resolution and format-specific parameters. Default settings are optimized for best results.
