Features
One-Click M4A to MP3
Drop an M4A file, hit Convert, download the MP3. No codec fiddling, no settings — the universal M4A-to-MP3 workflow in three clicks.
Clean MP3 Output
LAME encoder at VBR quality 2 — around 190 kbps on average, transparent for voice, music and podcasts.
Works With Any M4A
iTunes audiobooks, Apple Voice Memos, Garageband exports, AAC-encoded podcasts — whatever your M4A contains, you get a standards-compliant MP3.
Tags Preserved
Artist, title and album metadata from the M4A are copied over as ID3v2 tags in the MP3 so your library stays tidy.
Universal MP3 Playback
M4A only plays smoothly on Apple devices. MP3 plays on every phone, car stereo, podcast app and legacy player ever shipped.
Voice-Optimized Encoding
VBR allocates more bits to complex passages so spoken word stays natural while silence stays compact — ideal for voice memos.
Instant Playback
Output MP3 writes the ID3v2.3 header up front so players and podcast apps start immediately without re-buffering.
Seconds, Not Minutes
Audio-only re-encoding is dramatically faster than full video processing. A one-hour M4A converts in well under a minute.
100% Private, 100% Free
Your M4A never leaves your device. WebAssembly runs the converter directly in your browser tab — no server, no upload, no tracking.
Zero Server Upload
Files are read, converted and downloaded entirely on your own machine. We never see your audio or the MP3 you download.
No Watermark
The output MP3 is clean — no audio intro, no brand tag, no logo. Your audio, untouched.
Works Everywhere
Any modern browser on any device — Chrome, Firefox, Safari, Edge, desktop or mobile.
