About formats

M4A

M4A is an audio-only MPEG-4 container, commonly used for audio tracks purchased from the iTunes Store. It typically wraps AAC or ALAC audio. M4A offers better quality than MP3 at similar bitrates and is natively supported by Apple devices and most modern media players.

FLAC

FLAC (Free Lossless Audio Codec) is an open-source lossless audio format that compresses audio without discarding any information, typically reducing file size by 50-60% compared to WAV while allowing perfect reconstruction of the original signal. FLAC is the preferred format for high-fidelity music archives and audiophile collections.

Frequently Asked Questions

Is converting M4A to FLAC free?
Yes. This M4A → 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 M4A 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 M4A files uploaded to a server?
No. Files never leave your device. The entire M4A → FLAC conversion runs locally in your browser, so your data stays private.
Can I convert multiple M4A files at once?
Yes — batch conversion is supported. Add as many M4A 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 M4A to FLAC lose quality?
No. FLAC is a lossless format (or used in a lossless mode here), so the original data from your M4A file is preserved bit-for-bit in the converted result.
Does FLAC support transparency?
No — FLAC has no alpha channel. Transparent areas of your M4A file will be filled with a solid background colour in the converted file.
How will the file size change after converting M4A to FLAC?
Both formats use comparable compression, so the FLAC output will be similar in size to your M4A file — typically within 10–20% of each other.
