My iTunes library sounds so much better now
Converted my whole MP3 collection to M4A using Profi PDF. The files are smaller and the audio quality is noticeably cleaner. Should've done this years ago.

Fast and works perfectly with iPhone
Needed M4A files for my iPhone and had everything in MP3. Profi PDF converted them all in minutes and they synced to my phone without any issues. Brilliant.

No sign-up, no watermark, just the file
Tried a couple of other converters first — both wanted accounts. Profi PDF just converted my MP3 and let me download the M4A. Clean, fast, no drama.

Por Qué la Gente Elige Nuestras Herramientas de Audio y Video

Better Quality Than MP3

M4A uses AAC encoding which delivers better audio quality than MP3 at the same — or even smaller — file size. Profi PDF converts your MP3 to M4A so you get a genuine upgrade.

Perfect for Apple Devices

M4A is Apple's native audio format — it works seamlessly with iPhone, iPad, Mac, iTunes, and Apple Music. Profi PDF converts your MP3 so it fits right into the Apple ecosystem.

Smaller Files, Same Great Sound

M4A files are more efficient than MP3 — you get better audio in less storage space. Profi PDF converts your tracks so your library takes up less room without sounding worse.

Batch Convert Your Library

Got a whole music collection to upgrade? Profi PDF lets you queue up multiple MP3 files and convert them back to back. No repetitive uploading, no wasted time.

Transcribe It First

Need a text version of your audio before converting? Run your MP3 through Profi PDF AI transcription first, then convert to M4A. Full workflow, one platform.

Encrypted & Auto-Deleted

Your MP3 is locked with encryption on upload and wiped from Profi PDF servers the second your M4A is ready. Zero data stored, zero risk.
