Is WAV to AIFF conversion truly lossless?

Yes. Both WAV and AIFF store identical uncompressed PCM audio data. The conversion changes only the file container — the audio samples are bit-for-bit identical.

Will the file size change?

The files will be virtually identical in size since both contain uncompressed audio. AIFF may be a few bytes larger due to its slightly different header structure.

Why convert WAV to AIFF instead of using WAV in Logic Pro?

While Logic Pro can import WAV, AIFF is its native format with tighter integration. Some Logic Pro features and Apple Loops workflows work best with AIFF source files.

Does AIFF support 24-bit and high sample rate audio?

Yes. AIFF supports bit depths up to 32-bit and sample rates beyond 192 kHz, matching WAV's full capabilities for high-resolution audio.

Can I round-trip between WAV and AIFF without quality loss?

Yes. You can convert between WAV and AIFF as many times as needed with zero quality degradation because both are uncompressed PCM containers.

WAV to AIFF Converter

WAV and AIFF both contain uncompressed PCM audio, but AIFF is Apple's native standard with deeper integration in Logic Pro, GarageBand, and macOS. Converting WAV to AIFF ensures your uncompressed audio works optimally within Apple's professional audio ecosystem without any quality loss.

Convert AIFF to WAV instead

WAV to AIFF is a mathematically perfect, lossless container conversion. The PCM audio data is transferred bit-for-bit between the two formats. Bit depth, sample rate, and channel layout are preserved exactly.

How to Convert WAV to AIFF

About Our WAV to AIFF Converter

This converter uses FFmpeg compiled to WebAssembly (WASM) to transform your WAV 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 WAV 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 MP3, WAV, AAC, FLAC, and OGG for audio, 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.
