ALAC

ALAC (Apple Lossless Audio Codec) is a lossless audio codec developed by Apple and open-sourced in 2011. ALAC compresses audio without quality loss and is used in Apple Music's high-fidelity tier. ALAC files are typically stored in M4A containers and are supported by all Apple devices and most modern players.

Is converting ALAC to FLAC free?
Yes. This ALAC → FLAC converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert ALAC to FLAC?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my ALAC files uploaded to a server?
No. Files never leave your device. The entire ALAC → FLAC conversion runs locally in your browser, so your data stays private.
Can I convert multiple ALAC files at once?
Yes — batch conversion is supported. Add as many ALAC files as you like and convert them to FLAC in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting ALAC to FLAC lose quality?
No. FLAC is a lossless format (or used in a lossless mode here), so the original data from your ALAC file is preserved bit-for-bit in the converted result.
Does FLAC support transparency?
No — FLAC has no alpha channel. Transparent areas of your ALAC file will be filled with a solid background colour in the converted file.
How will the file size change after converting ALAC to FLAC?
Both formats use comparable compression, so the FLAC output will be similar in size to your ALAC file — typically within 10–20% of each other.
