FLAC to ALAC Converter

Convert FLAC files to ALAC format online for free. No installation or registration required.

Quick Answer: How to Convert FLAC to ALAC

FLAC is the Free Lossless Audio Codec — compresses audio 30–50% with zero quality loss. ALAC is Apple Lossless — FLAC's counterpart inside the MP4/M4A container. Converting between them re-encodes the media with ALAC's compression model, so output quality depends on the settings you pick in the converter. Run it free at practicalwebtools.com/convert/audio/flac-to-alac: drop in your FLAC, adjust settings if you like, and download the ALAC — no signup, no upload, everything stays on your device.

FLAC vs ALAC: Which One and Why

FLAC is the Free Lossless Audio Codec — compresses audio 30–50% with zero quality loss, released open-source by Xiph.Org in 2001. ALAC is Apple Lossless — FLAC's counterpart inside the MP4/M4A container, released by Apple in 2004; open-sourced under Apache 2.0 in 2011. People reach for FLAC mainly for archiving CD collections, audiophile listening, studio masters distribution, while ALAC is the usual choice for Apple Music lossless streaming, ripping CDs for the Apple ecosystem, iPhone/local-library audiophile setups. FLAC's headline strength: perfect fidelity — the decoded output is identical to the source. ALAC's: perfect fidelity inside the iTunes/Apple Music pipeline. On the other side of the ledger, FLAC limitation: still 4–6× larger than 320 kbps MP3 — and ALAC limitation: no advantage over FLAC outside the Apple world.

How to Convert FLAC to ALAC Online

  1. 1

    Add your FLAC file: Drag and drop it into the converter, or click to browse. FLAC files up to the size limit are accepted, and nothing is uploaded — processing runs locally in your browser.

  2. 2

    Set ALAC options: Pick your quality: the converter exposes the settings that matter for ALAC. Higher bitrates preserve more of the FLAC's detail at larger file sizes.

  3. 3

    Download the ALAC: Conversion runs on your device. When it completes, download the ALAC file — repeat for as many files as you need, free and unlimited.

Key Facts

  • FLAC: released open-source by Xiph.Org in 2001, lossless — decompresses bit-for-bit identical to the original.
  • ALAC: released by Apple in 2004; open-sourced under Apache 2.0 in 2011, lossless — roughly 40–60% of original size, comparable to FLAC.
  • FLAC strength: perfect fidelity — the decoded output is identical to the source.
  • ALAC strength: perfect fidelity inside the iTunes/Apple Music pipeline.
  • FLAC limitation to know: still 4–6× larger than 320 kbps MP3.
  • ALAC limitation to know: no advantage over FLAC outside the Apple world.
  • Fun fact: Apple Music streams ALAC up to 24-bit/192 kHz — but AirPods re-compress it to AAC over Bluetooth, so lossless is only audible on wired or Wi-Fi playback

Format Background

FLAC

FLAC — released open-source by Xiph.Org in 2001. FLAC's MD5 checksum of the raw audio lets you verify an archive is still bit-perfect years later — no other common audio format does this

ALAC

ALAC — released by Apple in 2004; open-sourced under Apache 2.0 in 2011. Apple Music streams ALAC up to 24-bit/192 kHz — but AirPods re-compress it to AAC over Bluetooth, so lossless is only audible on wired or Wi-Fi playback

Frequently Asked Questions

Will converting FLAC to ALAC lose quality?

It depends on the formats: FLAC is lossless — decompresses bit-for-bit identical to the original and ALAC is lossless — roughly 40–60% of original size, comparable to FLAC. Any step from a lossless source into ALAC keeps everything; any lossy step re-encodes and discards some data.

Are my files uploaded anywhere during FLAC → ALAC conversion?

No. This converter runs on WebAssembly inside your browser — your FLAC file is read from disk, processed by your device's CPU, and the ALAC is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.

Does the converter keep metadata (title, artist, cover art)?

Where the ALAC container supports it, standard tags are carried across. Apple Music streams ALAC up to 24-bit/192 kHz — but AirPods re-compress it to AAC over Bluetooth, so lossless is only audible on wired or Wi-Fi playback

What ALAC settings should I choose?

For Apple Music lossless streaming, start with the converter's default preset — it's tuned for the common case. If you need smaller files, step quality down gradually and listen or look at the result before batch-converting everything.
