FLAC to AIFF
Convert FLAC audio to AIFF — right in your browser, nothing uploaded.
Drag & drop your FLAC files here, or click to choose. Everything runs in your browser — nothing is uploaded.
FLAC is a lossless codec that compresses audio to about half of WAV’s size with no quality loss — the archival and audiophile choice. People convert FLAC to AIFF because Logic Pro and Mac audio workflows use uncompressed AIFF. This free FLAC-to-AIFF converter does the whole job inside your browser using a WebAssembly build of FFmpeg, so your audio is never uploaded to any server and there is no size limit or queue. Drop in one file or a whole batch, and each file converts automatically — then preview every result in place and download it. No signup, no watermark, and nothing to install.
Frequently Asked Questions
How do I convert FLAC to AIFF?
To convert FLAC to AIFF, drag your FLAC files onto the drop area or click to choose them, and each converts to AIFF automatically the moment it is added — there is no format to pick and no convert button. When a file finishes it appears as a row with its new name, size, an inline player to preview it and a Download button, and everything runs in your browser so nothing is uploaded.
Is this FLAC to AIFF converter free and private?
Yes on both counts: it is completely free with no signup, no watermark and nothing to install, and it is private because the whole conversion runs on a WebAssembly build of FFmpeg inside your own browser rather than on a server, so your files never leave your device. That makes it safe for private or unreleased recordings. The only download is the converter itself, a one-time roughly 32 MB file that is cached afterwards.
Will converting FLAC to AIFF lose quality?
No. FLAC and AIFF are both lossless, so your audio is preserved exactly with nothing thrown away — the AIFF holds the same samples the FLAC did. The main change is file size, since the two formats compress differently. If archiving matters, keep your originals as well as the new AIFF files.
Why convert FLAC to AIFF?
People convert FLAC to AIFF because Logic Pro and Mac audio workflows use uncompressed AIFF. AIFF is uncompressed PCM audio developed by Apple — perfect quality but large files, and the standard in Logic Pro and older Mac audio work. Converting re-packages your existing FLAC audio into AIFF so it drops straight into that device, app or workflow, without changing how the original was recorded.
Is there a file size or number limit?
There is no fixed size or count limit, because nothing is uploaded — you can drop many FLAC files at once and each is converted separately with its own preview player and Download button. The only real limit is your device’s memory, so very large files of several hundred megabytes convert more comfortably on a desktop than on a phone.
Does it work on iPhone, Mac and Android?
Yes, it runs in any modern browser on Windows, Mac, Linux, iPhone and Android, with nothing to install and no account needed, so you can convert FLAC to AIFF on a laptop or straight from your phone. The first use downloads a one-time converter of about 32 MB, which your browser then caches so later conversions start instantly.
