The AAC audio inside your M4A is decoded and stored losslessly as FLAC. Future edits and conversions then cost nothing in quality, and the file joins lossless libraries and tools without friction.
Be aware of what this is not: detail already discarded by the original AAC encode is unrecoverable, so the FLAC sounds exactly like the M4A.
Consistency in a FLAC-based archive, compatibility with lossless-only software, and protecting recordings before editing are the practical wins. iPhone voice memos destined for serious editing benefit from a one-time decode to FLAC so each save does not re-compress.
No, identical. The conversion preserves current quality and prevents future loss. It cannot recreate what AAC compression removed.
FLAC supports rich metadata, and you can review or edit tags after conversion with the audio metadata tools.
Yes, fully in-browser. Voice memos and private recordings never leave your device.
