AIFF to FLAC Converter
Drop an AIFF file to inspect its metadata, then follow the step-by-step guide to convert it to FLAC with FFmpeg, Audacity, or a free online converter.

.aiff and .aif files — nothing is uploaded

Header parse note: values read directly from AIFF COMM chunk bytes.
Could not parse AIFF header — size and filename shown only. Use FFmpeg to inspect full details.
Auto-filled when you select a file. Edit freely.
FFmpeg Command
ffmpeg -i "input.aiff" -c:a flac "output.flac"
Batch Convert (Linux / macOS)
for f in *.aiff; do
ffmpeg -i "$f" -c:a flac "${f%.aiff}.flac"
done
Batch Convert (Windows CMD)
for %f in (*.aiff) do ffmpeg -i "%f" -c:a flac "%~nf.flac"
Step-by-Step Conversion Methods
FFmpeg (Recommended)
- 1.Download FFmpeg from ffmpeg.org and add it to your PATH.
- 2.Open a terminal in the folder containing your AIFF file.
- 3.Run the command generated above (or use the batch loop for multiple files).
- 4.The FLAC file appears in the same folder — bit-perfect, lossless.
Works on Windows, macOS, and Linux. Free and open-source.
Audacity (GUI)
- 1.Install Audacity from audacityteam.org.
- 2.Open your AIFF file via File > Open.
- 3.Go to File > Export > Export as FLAC.
- 4.Choose a compression level (5 is default), click Save.
No terminal needed. Free GUI available on all major platforms.
Online Converters
- 1.Visit a service such as Convertio, CloudConvert, or FreeConvert.
- 2.Upload your AIFF file (check the site's file-size limit).
- 3.Select FLAC as the output format and start the conversion.
- 4.Download the converted FLAC file.
Easy but requires uploading your file to a third-party server.
AIFF vs FLAC: Format Comparison
| Property | AIFF | FLAC |
|---|---|---|
| Compression | None (uncompressed PCM) | Lossless (typically 40–60% smaller) |
| Audio quality | Bit-perfect | Bit-perfect (identical to source) |
| Platform support | Primarily Apple (macOS, iOS) | Cross-platform (Windows, Linux, macOS, Android) |
| Streaming support | Limited (Tidal, Apple Music) | Tidal, Deezer, Qobuz, and more |
| Metadata (tags) | ID3 or proprietary chunks | Vorbis comment tags (flexible, widely supported) |
| Max bit depth | Up to 32-bit | Up to 32-bit |
| Max sample rate | Up to 192 kHz | Up to 655,350 Hz |
| Typical file size (1 min stereo 16-bit/44.1 kHz) | ~10 MB | ~4–6 MB |
| Open standard | No (Apple proprietary) | Yes (Xiph.Org, royalty-free) |
Summary
Drop an AIFF file to inspect its metadata, then follow the step-by-step guide to convert it to FLAC with FFmpeg, Audacity, or a free online converter.
How it works
- Drop or select your AIFF (.aiff / .aif) file into the analyzer.
- The browser reads the file header bytes and displays format details — nothing leaves your device.
- Review the detected sample rate, bit depth, channel count, and estimated duration.
- Copy the generated FFmpeg command and run it in your terminal.
- Alternatively, follow the Audacity or online-converter steps shown below.
Use cases
- Convert Apple GarageBand or Logic Pro AIFF exports to FLAC for archiving.
- Reduce AIFF file size before uploading to FLAC-friendly streaming services.
- Share lossless audio with collaborators on non-Apple platforms.
- Migrate a macOS music library to a cross-platform lossless format.
- Verify AIFF metadata (sample rate, bit depth) before conversion.
- Batch-convert a folder of AIFF masters to FLAC using the shell loop commands.
- Understand the differences between AIFF and FLAC before choosing a format.
