MP3 to MP2 Conversion FAQ
How do I convert MP3 audio to MP2 without losing quality?
+
Upload the MP3 file and the converter chooses the MP2 codec and bitrate to match the source. Lossless MP2 (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy MP2 (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears. MP3 is lossy: a psychoacoustic model discards frequencies the ear is unlikely to notice, typically at 128 to 320 kbps. MP2 is lossy but uses a simpler filterbank than MP3, typically running at 192 to 384 kbps.
Is converting MP3 to MP2 a second round of lossy compression?
+
Yes, and it is worth planning around. Both formats are lossy, so the MP2 encoder is working from audio that has already been through one psychoacoustic pass, and its own decisions compound the first set. At 192 kbps or above the result is still transparent for most listening. If you have a lossless master anywhere, encoding the MP2 from that instead avoids the double pass entirely.
Will my track titles and album art survive the MP3 to MP2 conversion?
+
Not intact. MP3 carries a proper metadata block, but MP2 has no standard place for artist, album, track number or cover art, so tags are dropped rather than mangled. Keep the MP3 as the tagged copy, or re-tag afterwards with a tool like Mp3tag or MusicBrainz Picard. MP2 needs far more bitrate than MP3 or AAC for the same quality and is unknown to most consumer software.
What bitrate will the resulting MP2 file use?
+
Default is 192 kbps for lossy MP2; pass-through for lossless MP2. 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 MP2 reduce my audio quality?
+
If MP3 is lossy and MP2 is lossless (e.g. MP3 → WAV), the MP2 is no better than the MP3 — you cannot recover information already discarded. If MP3 is lossless and MP2 is lossy, the MP2 codec recompresses; at 192 kbps the result is transparent for most content.
Does the MP3 to MP2 converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and album art are read from the MP3 container and written into the MP2 container where the format supports tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not. MP2 is MPEG-1 Audio Layer II, the layer that predates MP3 and became the audio standard for DVB and DAB broadcasting.
Can I batch convert hundreds of MP3 files to MP2?
+
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.
Will the MP2 keep the same sample rate as MP3?
+
By default yes — 48 kHz MP3 stays 48 kHz in MP2. If you need to downsample for compatibility (96 kHz → 44.1 kHz for CD burning), the sample-rate option applies high-quality resampling in the same encode pass.
Can I normalize loudness when converting MP3 to MP2?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the MP2, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
Will my MP2 play on car stereo, iPod, and Sonos?
+
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 an MP2 codec optimized for your target hardware. MP2 is extremely robust to bit errors and cheap to decode, which is why broadcast chains stayed on it long after MP3 arrived.
Is my MP3 file private during conversion to MP2?
+
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/.
How long does converting a 1-hour MP3 to MP2 take?
+
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 → MP2 finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
