Convert M4A to FLAC when you are archiving music without losing a single bit. M4A is AAC audio in an MP4 wrapper — Apple’s music format, better quality than MP3 at the same file size; FLAC is lossless audio compression — every bit of the original preserved at roughly half the size of WAV, the archivist’s music format. Upload your M4A, hit convert, download the FLAC — free, no sign-up, no watermark.
Files arrive in whatever format the sender fancied; the M4A to FLAC Converter is part of a documents-forward bench on ConvertFiles built for that moment — Office and PDF both ways, with images, audio and video converted in the same visit, and everything deleted the moment you download.

M4A is AAC audio in an MP4 wrapper — Apple’s music format, better quality than MP3 at the same file size. FLAC is lossless audio compression — every bit of the original preserved at roughly half the size of WAV, the archivist’s music format. The audio is decoded once and re-encoded as FLAC; tags and artwork are not carried across, so re-add them in your player if they matter. File sizes stay in the same ballpark — both formats compress with loss, so the FLAC lands within roughly a third of the M4A's size at these quality settings. People make this exact swap when you are archiving music without losing a single bit.

Why people pick this over other converters
No account, ever. Most big converter sites push sign-ups and paid tiers for basic jobs. Here the tool just works.
No watermarks and no job counters on standard tools — fair-use rate limits keep things fast for everyone — and a generous 200 MB upload limit.
Private by design: your file is processed in a temporary folder and deleted the moment your download finishes. Nothing is stored or shared.
Fast: this page is a fraction of the size of the ad-heavy alternatives, and the same account-free toolbox has 386 other tools when you need them.
FAQ
Will converting M4A to FLAC lose quality?
The FLAC will be a bit-perfect copy of what is in your M4A — but M4A already threw detail away when it was created, and no conversion can invent it back. Expect a much bigger file with exactly the same quality, which is worth it only for editing or archiving.
When should I convert M4A to FLAC?
Convert when you are archiving music without losing a single bit. If your M4A already opens where you need it, converting buys nothing — this swap earns its keep the moment a device, app or upload form refuses M4A but accepts FLAC.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
