When to Convert
Common scenarios where this conversion is useful
Importing lossless audio into Logic Pro
Logic Pro does not natively import FLAC files in all versions. Convert FLAC to AIFF for direct drag-and-drop import into Logic Pro projects with full lossless quality.
GarageBand sample libraries
GarageBand supports AIFF natively. Convert FLAC samples and loops to AIFF for use in GarageBand's Audio Files browser and EXS24 sampler instruments.
Professional audio mastering on macOS
Mastering engineers on macOS often request AIFF deliverables. Convert FLAC masters to AIFF for delivery to clients using Logic Pro or other macOS-native DAWs.
Embedding loop markers for samplers
AIFF supports embedded loop point metadata via MARK and INST chunks. Convert FLAC samples to AIFF before adding loop points for use in hardware and software samplers.

Download your AIFF file
Download the resulting AIFF file. Note it will be larger than the FLAC source since AIFF is uncompressed. The file is auto-deleted from our servers after download.
Frequently Asked Questions
Yes. Both FLAC and AIFF are lossless formats. FLAC stores compressed lossless audio, while AIFF stores uncompressed PCM audio. Converting between them produces no quality loss — the audio data is identical.
FLAC uses lossless compression to reduce file size, while AIFF stores raw uncompressed PCM audio. The same audio data takes up more space uncompressed. This is normal and expected.
Logic Pro added FLAC support in version 10.5 (2020). If you have an older version, or if you need AIFF for compatibility reasons, this converter provides the right output.
Yes. FFmpeg preserves the original bit depth from the FLAC file (16-bit or 24-bit) when creating the AIFF output, ensuring studio-quality audio is maintained.
Both are equivalent in audio quality as uncompressed PCM formats. AIFF has advantages on macOS (native Logic Pro support, loop metadata support). WAV has broader platform support including Windows and Linux.
Partially. Basic metadata like title, artist, and album may transfer. However, FLAC uses Vorbis comment tags while AIFF uses its own metadata chunk format, so some fields may not map perfectly.
Yes. FFmpeg handles 24-bit FLAC files and outputs 24-bit AIFF, which is suitable for high-resolution professional audio workflows requiring 24-bit precision.
Yes. Your file is uploaded over HTTPS, processed by FFmpeg on our secure server, and automatically deleted after download. We do not retain or access your audio content.
Yes. Pro Tools supports AIFF files alongside its native BWF/WAV format. AIFF is widely accepted in professional DAW environments including Pro Tools, Logic Pro, and Nuendo.
