How do I convert M4A to FLAC?

Upload your M4A file using the box above, confirm FLAC as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting M4A to FLAC free?

Yes, and there is nothing to sign up for. Every conversion is free, there is no paid tier, and the limits are the same for everyone.

Will the quality change when converting to FLAC?

Converting to FLAC is lossless, but it cannot restore detail that the original M4A file already discarded. The result matches the source exactly as it is.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.
