AVI to AIFF Audio Extractor
AVI files from camcorders and legacy video archives often need their audio imported into Mac-based production tools. Extracting to AIFF decodes the AVI audio into Apple's native uncompressed format, ready for editing in Logic Pro, GarageBand, and other professional Apple audio applications.
AVI audio is decoded to uncompressed PCM in AIFF format. If the AVI contains PCM audio, this is essentially a lossless container conversion. For MP3 or AC3 AVI audio, the AIFF faithfully captures the decoded audio.
How to Convert AVI to AIFF
- 1
Upload your AVI video file to the converter.
- 2
Select AIFF as the audio output format.
- 3
Click Convert and download the uncompressed AIFF audio.

This converter uses FFmpeg compiled to WebAssembly (WASM) to transform your AVI files into AIFF format entirely inside your web browser. When you select a file for conversion, the processing happens locally on your device. Your file is never uploaded to any server, never transmitted over the internet, and never stored anywhere outside your own computer. This privacy-first architecture makes our tool safe for confidential and sensitive content — including legal recordings, medical files, financial presentations, personal media, and any other material you would not want on a third-party server.
The conversion process works by decoding the AVI input using FFmpeg's highly optimized decoders, then encoding the output in AIFF format with carefully tuned settings that balance quality and file size. When possible, the tool uses stream copy mode to remux (rewrap) compatible streams without re-encoding, which preserves the original quality with zero generational loss. When re-encoding is necessary due to codec differences between the two formats, the converter uses high-quality encoding settings to minimize any visible or audible quality reduction.
Supported input formats include MP4, MOV, AVI, MKV, and WebM for video, with automatic detection of the codecs and parameters inside your source file. The output is optimized for maximum compatibility with modern devices and platforms including Windows, macOS, Linux, iOS, Android, smart TVs, and all major web browsers.
Why browser-based conversion is safer: traditional online converters require you to upload your file to a remote server, where it is processed by third-party infrastructure and then made available for download. This workflow exposes your data to interception during upload, unauthorized access on the server, unclear data retention policies, and potential data breaches. Professionals in regulated industries such as healthcare (HIPAA), legal (attorney-client privilege), and finance (SOX, GDPR) often cannot use server-based converters without violating compliance requirements. Our WebAssembly-powered approach eliminates all of these risks by ensuring your data never leaves the browser sandbox on your own device.
The tool handles files up to 500 MB on desktop browsers and 200 MB on mobile devices. No account registration, no software installation, and no recurring subscription is required. Conversion typically completes in seconds for small files and a few minutes for larger ones, depending on your device's processing capabilities. Once the conversion is finished, you can download the result immediately and the source data is discarded from browser memory.
