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 / bitrate combination that matches the source profile. Lossless MP2 (WAV / FLAC / ALAC) preserves every sample exactly; lossy MP2 (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for almost all music content. 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 does the MP2 file end up at?
+
Default 192 kbps for lossy MP2; pass-through for lossless MP2. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-constrained podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.
Will going from MP3 to MP2 actually reduce my audio quality?
+
If MP3 is lossy (MP3, AAC) and MP2 is lossless (WAV, FLAC), the MP2 is no better than the MP3 — you cannot recover information already discarded by the lossy MP3 codec. If MP3 is lossless and MP2 is lossy, expect the MP2 encoder to recompress; at 192 kbps the loss is imperceptible to most ears.
Does the MP3 to MP2 converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art, BPM, replay-gain are read from the MP3 container and written into the equivalent fields on the MP2 container. ID3v2 (MP3), Vorbis comments (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chunks all map cleanly. 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 into 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. Folder structure is preserved in the output ZIP.
Will the MP2 keep the same sample rate as the MP3?
+
By default yes (a 48 kHz MP3 produces 48 kHz MP2, a 44.1 kHz MP3 produces 44.1 kHz MP2). For specific compatibility — e.g. downsampling 96 kHz studio masters to 44.1 kHz MP2 for CD burning, or upsampling 22 kHz voicemail to 44.1 kHz MP2 — the sample-rate dropdown applies high-quality SOX-style resampling.
Can I normalize loudness in the MP3 to MP2 step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the MP2 output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard) or a custom value. Useful when batch-converting tracks with varying mastering levels into a single MP2 playlist.
Will the MP2 play on my car stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays universally on every device made in the last 20 years. AAC plays on Apple, most Android, Sonos, and modern car stereos. FLAC plays on Sonos and recent Android, less well on older iPods. WAV plays on everything but the file is huge. The device-target dropdown picks a safe MP2 codec for the platform you specify. 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?
+
Yes — uploaded MP3 files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. The pipeline runs on hardware we control end-to-end; no third-party services receive your file.
How long does converting a 1-hour MP3 to MP2 take?
+
Same-codec re-mux (e.g. AAC inside M4A -> AAC inside MP4): 10-30 seconds. Codec change (e.g. FLAC -> MP3 or WAV -> AAC): typically 10-20% of source duration, so a 1-hour MP3 -> MP2 finishes in 6-12 minutes on the standard pipeline.
