iPhone voice memos and Apple Music downloads come as M4A, which some non-Apple apps and players won't open. Converting M4A to FLAC gives you bit-perfect, lossless audio at roughly half the size of WAV — ideal for archiving and audiophile libraries. Picmal converts locally on your Mac with batch processing.
Drag and drop one file or a whole folder.
Pick the output format and quality.
Click Convert. Everything runs on your Mac.

Open Picmal, drag your M4A files into the window, choose FLAC as the output format, set your quality, and click Convert. Everything runs locally on your Mac.
Yes. Drag in as many M4A files (or a whole folder) as you like and Picmal converts them all to FLAC in one pass.
No. FLAC is lossless, but it can't recover detail that lossy M4A already discarded. You get a pristine, editable file — not better-than-source audio.
Picmal is a one-time purchase of $15.99 — no subscription, no per-file limits, no watermark. Download to explore the interface; 14-day money-back guarantee.
