Quick Answer: How to Convert M4P to FLAC
M4P is a protected (DRM) AAC audio file from the iTunes Store era, while FLAC is the Free Lossless Audio Codec — compresses audio 30–50% with zero quality loss. Converting M4P to FLAC wraps or re-encodes your audio into the FLAC structure, but be aware: quality lost when the M4P was created stays lost — a FLAC made from a lossy source is a perfect copy of an imperfect original. Run it free at practicalwebtools.com/convert/audio/m4p-to-flac: drop in your M4P, adjust settings if you like, and download the FLAC — no signup, no upload, everything stays on your device.
M4P vs FLAC: Which One and Why
M4P is a protected (DRM) AAC audio file from the iTunes Store era, Apple, 2003–2009 — iTunes Plus (2007+) and full DRM removal (2009) ended it. FLAC is the Free Lossless Audio Codec — compresses audio 30–50% with zero quality loss, released open-source by Xiph.Org in 2001. People reach for M4P mainly for legacy iTunes purchases (pre-2009), while FLAC is the usual choice for archiving CD collections, audiophile listening, studio masters distribution. M4P's headline strength: none today — the DRM adds only restrictions. FLAC's: perfect fidelity — the decoded output is identical to the source. On the other side of the ledger, M4P limitation: FairPlay-protected audio cannot be converted by any tool, including this one — only Apple-authorized playback works — and FLAC limitation: still 4–6× larger than 320 kbps MP3.
How to Convert M4P to FLAC Online
- 1
Add your M4P file: Drag and drop it into the converter, or click to browse. M4P files up to the size limit are accepted, and nothing is uploaded — processing runs locally in your browser.
- 2
Set FLAC options: The converter re-encodes into FLAC, which is lossless — decompresses bit-for-bit identical to the original. Set quality to maximum since you're going lossless — no reason to trim bits you already have.
- 3
Download the FLAC: Conversion runs on your device. When it completes, download the FLAC file — repeat for as many files as you need, free and unlimited.
Key Facts
- M4P: Apple, 2003–2009 — iTunes Plus (2007+) and full DRM removal (2009) ended it, AAC inside MP4 with FairPlay DRM.
- FLAC: released open-source by Xiph.Org in 2001, lossless — decompresses bit-for-bit identical to the original.
- Converting M4P → FLAC cannot restore what the M4P encoding already discarded — the FLAC is a faithful copy of the M4P, not of the original recording.
- M4P strength: none today — the DRM adds only restrictions.
- FLAC strength: perfect fidelity — the decoded output is identical to the source.
- M4P limitation to know: FairPlay-protected audio cannot be converted by any tool, including this one — only Apple-authorized playback works.
- FLAC limitation to know: still 4–6× larger than 320 kbps MP3.
- Fun fact: FLAC's MD5 checksum of the raw audio lets you verify an archive is still bit-perfect years later — no other common audio format does this

M4P — Apple, 2003–2009 — iTunes Plus (2007+) and full DRM removal (2009) ended it. there is no legitimate M4P converter: the audio is encrypted. Re-download as M4A from iTunes, or use iTunes Match to upgrade

Frequently Asked Questions
Will converting M4P to FLAC lose quality?
The FLAC output preserves everything present in your M4P file — but M4P is AAC inside MP4 with FairPlay DRM, so information discarded when that file was made is gone for good. You get a bit-perfect copy of what you have, not a restoration of the original recording.
Are my files uploaded anywhere during M4P → FLAC conversion?
No. This converter runs on WebAssembly inside your browser — your M4P file is read from disk, processed by your device's CPU, and the FLAC is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
Does converting M4P to FLAC restore lost quality?
No — and this trips up a lot of people. M4P is AAC inside MP4 with FairPlay DRM: the data it discarded at creation time cannot be reconstructed by any converter. A FLAC from a M4P source sounds exactly as good as the M4P, no better. The reasons to convert anyway are compatibility, editing headroom, and future-proofing — not restoration.
Can I convert several M4P files at once?
Yes — the converter processes a queue of files in one session, each entirely on your device. Batch mode is handy when moving a library into FLAC; just remember each file re-encodes independently, so set your quality once and it applies to all.
What's the difference between M4P and FLAC technically?
M4P is a protected (DRM) AAC audio file from the iTunes Store era (Apple, 2003–2009 — iTunes Plus (2007+) and full DRM removal (2009) ended it). FLAC is the Free Lossless Audio Codec — compresses audio 30–50% with zero quality loss (released open-source by Xiph.Org in 2001). In practice, M4P is typically used for legacy iTunes purchases (pre-2009), while FLAC is the usual choice for archiving CD collections, audiophile listening, studio masters distribution.
