MP3 to MP2 Conversion FAQ
Is the MP3 to MP2 conversion reversible?
+
You can convert the MP2 back to MP3 on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What output quality should I expect from MP3 to MP2?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
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. 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.
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 exactly is an MP2 file?
+
A bare run of encoded audio frames with no container wrapped around them. That is why two MP2 files can usually be joined by simply putting one after the other, and equally why everything beyond the audio itself — a length, a seek index, cover art — has to be bolted on as a convention rather than being part of the format, so a player often has to read the whole file to work out how long it is. It is about the simplest thing that can be called an audio file, which is exactly why it turns up inside other containers more often than on its own.
Is MP3 free to use and distribute?
+
Yes, without conditions worth worrying about. The specification is public, anyone can implement an encoder or decoder without asking or paying, and nobody can change those terms later — which is why it turns up in open-source tooling, in game engines and anywhere a licence negotiation would have killed the project. Converting away from it does not undo that; the files you already have stay exactly as usable as they were.
Why would anyone still convert to MP2?
+
For one specific piece of software or hardware that will accept nothing else — which is a real situation and the only good reason. MP2 belongs to an earlier generation: newer codecs do the same job at smaller sizes, general-purpose players drop support for it rather than adding it, and nothing new is being built around it. If something in the chain genuinely demands it, convert and keep the original as the master. If nothing does, convert away from it instead.
Who defines MP2?
+
A standards body rather than a company, which is most of the reason it is everywhere. MP2 was specified through the international process that produces the MPEG standards, so broadcasters, phone manufacturers, browser vendors and streaming services all implemented the same document instead of licensing somebody's product. The practical consequence is boring and useful: an MP2 made by one tool decodes identically in another, and there is no vendor whose support could be withdrawn. MP2 is MPEG-1 Audio Layer II, the layer that predates MP3 and became the audio standard for DVB and DAB broadcasting.
Is there a file-size limit when converting MP3 to MP2?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I batch-convert several MP3 files to MP2 at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What happens to my MP3 files after the conversion?
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
What apps can play a MP2 file?
+
MP2 plays in most music players, browsers, and media libraries. iTunes / Apple Music, VLC, Foobar2000, and phone media apps handle it natively.
