About formats

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 FLAC to M4A free?
Yes. This FLAC → M4A 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 FLAC to M4A?
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 FLAC files uploaded to a server?
No. Files never leave your device. The entire FLAC → M4A conversion runs locally in your browser, so your data stays private.
Can I convert multiple FLAC files at once?
Yes — batch conversion is supported. Add as many FLAC files as you like and convert them to M4A 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 FLAC to M4A reduce the quality?
Because both formats use lossy compression, the M4A output will not bring back any quality that has already been lost in your FLAC file. Avoid repeated re-encoding to keep the best quality.
Does M4A support transparency?
No — M4A has no alpha channel. Transparent areas of your FLAC file will be filled with a solid background colour in the converted file.
Will the converted M4A file be smaller than the FLAC?
Usually yes. Converting from a lossless or uncompressed format to a lossy one dramatically reduces file size. Typical savings range from 50% to 90%, depending on the quality setting you choose.
