FLAC to ALAC
Convert FLAC audio to ALAC — 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 ALAC because ALAC gives bit-perfect lossless audio that plays natively on Apple devices. This free FLAC-to-ALAC 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. The result is a lossless .m4a file. No signup, no watermark, and nothing to install.
Frequently Asked Questions
How do I convert FLAC to ALAC?
To convert FLAC to ALAC, drag your FLAC files onto the drop area or click to choose them, and each converts to ALAC 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 ALAC 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 ALAC lose quality?
No. FLAC and ALAC are both lossless, so your audio is preserved exactly with nothing thrown away — the ALAC 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 ALAC files.
Why convert FLAC to ALAC?
People convert FLAC to ALAC because ALAC gives bit-perfect lossless audio that plays natively on Apple devices. ALAC (Apple Lossless) is Apple’s lossless codec, stored inside an .m4a file — identical audio to the source, smaller than WAV, and native to iTunes and Apple Music. Converting re-packages your existing FLAC audio into ALAC so it drops straight into that device, app or workflow, without changing how the original was recorded.
What file extension does the ALAC file use?
Your ALAC file is saved with a .m4a extension, because Apple Lossless has no container of its own and always lives inside an MP4/M4A file — that .m4a is genuine lossless ALAC, not lossy AAC. It plays natively in iTunes, Apple Music, Finder and on the iPhone, and most modern players recognise it too.
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 ALAC 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.
