Convert FLAC to AIFF Online
Still 3–5x larger than high-quality lossy codecs (AAC/Opus at 256 kbps) while the difference is inaudible to most listeners. Converting to AIFF gives you a key advantage: stores uncompressed pcm audio with rich metadata (artwork, lyrics, comments) in one file — something wav historically lacked. AIFF is best for uncompressed audio on macos with embedded metadata — apple's equivalent of wav.
Why Convert FLAC to AIFF?
Still 3–5x larger than high-quality lossy codecs (AAC/Opus at 256 kbps) while the difference is inaudible to most listeners — converting to AIFF overcomes this by providing stores uncompressed pcm audio with rich metadata (artwork, lyrics, comments) in one file — something wav historically lacked
AIFF is the right choice when you need to: exchanging uncompressed audio between macos-based music production tools
Gain broader compatibility — AIFF works with macOS (native), Logic Pro, GarageBand, Pro Tools, VLC, most DAWs; Windows support via third-party players
Your FLAC files were created for archiving cd rips with proof of lossless integrity via embedded md5 checksums, but now you need a format suited to different workflows

How to Convert FLAC to AIFF
Upload your FLAC file
Drag your .flac file onto the upload area or click to browse. We accept FLAC files up to 500 MB.
Choose AIFF as output format
Select .aiff (Audio Interchange File Format) from the format list. AIFF uses lossless encoding, so your output quality matches the source.
Convert and download
Click Convert and wait for processing. Your AIFF file will be ready to download in seconds. The result is optimized for uncompressed audio on macos with embedded metadata — apple's equivalent of wav.
Frequently Asked Questions
Is the FLAC to AIFF conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. Uncompressed PCM, up to 32-bit / 192 kHz, with embedded metadata chunks for album art and tags.
How large will my AIFF file be compared to the original FLAC?
expand_more
FLAC files are typically 15 MB – 50 MB per song, while AIFF files are typically 10 MB – 100 MB per minute. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted AIFF file?
expand_more
AIFF is compatible with: macOS (native), Logic Pro, GarageBand, Pro Tools, VLC, most DAWs; Windows support via third-party players.
What is the maximum file size I can convert?

PureConverter accepts FLAC files up to 500 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between FLAC and AIFF?
expand_more
FLAC (Free Lossless Audio Codec) is best for archiving music collections at cd quality with ~50% file size reduction and bit-perfect playback. AIFF (Audio Interchange File Format) is best for uncompressed audio on macos with embedded metadata — apple's equivalent of wav. Key tradeoff: FLAC's advantage is lossless compression reduces file sizes by 40–60% while guaranteeing bit-perfect reconstruction of the original audio, while AIFF's advantage is stores uncompressed pcm audio with rich metadata (artwork, lyrics, comments) in one file — something wav historically lacked.
Pro Tips for FLAC to AIFF Conversion
AIFF preserves full quality, so your output file will be as good as the FLAC source — no need to worry about compression artifacts
Keep a backup of your original FLAC file — while our conversion is reliable, having the source is always recommended
AIFF works especially well for: archiving studio masters on macos where wav metadata support was historically poor
Did you know? AIFF was based on Electronic Arts' IFF (Interchange File Format) from the Amiga — Apple adapted the Amiga's file structure for Macintosh audio, which is why AIFF uses big-endian byte order while WAV uses little-endian.
