Default is 192 kbps for lossy M4R; pass-through for lossless M4R. Override to 320 kbps for audiophile or 96 kbps for voice / podcast. The choice trades file size against audible fidelity; below 96 kbps lossy artifacts become noticeable on music.
Will going from MP3 to M4R reduce my audio quality?
+
If MP3 is lossy and M4R is lossless (e.g. MP3 → WAV), the M4R is no better than the MP3 — you cannot recover information already discarded. If MP3 is lossless and M4R is lossy, the M4R codec recompresses; at 192 kbps the result is transparent for most content.
Yes — drop a folder of MP3 files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.

MP3 plays everywhere. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and Android but not on older iPods. WAV plays on everything but is huge. The advanced device-preset dropdown picks a M4R codec optimized for your target hardware.
Is my MP3 file private during conversion to M4R?
+
Yes — uploaded MP3 files are processed in isolated workers and deleted within minutes. We never play back, store long-term, or share the audio content. The full retention window is in /privacy/.
Same-codec re-mux: 10 to 30 seconds. Re-encode to a different codec: typically 10 to 20% of source duration, so a 1-hour MP3 → M4R finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.

No automatic gain change happens unless you enable the normalize option. If you observe a level change, your audio player or media library is likely applying ReplayGain or per-track normalization on playback — not us. Disable that to hear the true M4R levels.
