MP2 to MKV Conversion FAQ
How do I convert an MP2 file to MKV?
+
Upload your MP2 file using the picker above and the converter detects the source type and runs the MP2 -> MKV pipeline. The result downloads automatically when conversion completes; no account is needed for one-off conversions. MP2 is MPEG-1 Audio Layer II, the layer that predates MP3 and became the audio standard for DVB and DAB broadcasting. MKV is Matroska, an open container designed in 2002 with no licensing restrictions and no ceiling on what it can hold.
What will the picture be if I put MP2 audio into an MKV file?
+
You choose it, because audio alone has no picture. The default is a static waveform render, and you can supply a still image instead — cover art, a title card, a photo — which is held for the whole duration. That is what makes the file uploadable to video-only platforms that will not accept a bare audio track. MKV is the archival container of choice because it stores unlimited audio tracks, soft subtitles, chapter markers and cover art in one file.
Is the MP2 audio re-encoded when it goes into the MKV?
+
Only if it has to be. Where the MKV container accepts the source audio codec directly, the stream is copied in untouched and stays bit-identical. Where it does not, the audio is transcoded once to whatever MKV does accept, at a bitrate matched to the source so the second pass costs as little as possible. MP2 is lossy but uses a simpler filterbank than MP3, typically running at 192 to 384 kbps. MKV is codec-agnostic: H.264, HEVC, VP9 and AV1 video sit happily beside AAC, FLAC, Opus, DTS or Dolby audio in the same file.
How large will the MKV be compared with the MP2?
+
Barely larger, if you use the default still image. A single held frame compresses to almost nothing across the whole duration because every frame is identical to the last, so the file is dominated by the audio track. Choosing an animated waveform instead adds real video data and can double or triple the result.
Will a surround mix in the MP2 stay surround inside the MKV?
+
Yes — MKV carries multichannel audio properly, so a 5.1 mix stays 5.1 with the channel layout intact rather than being folded to stereo. That matters if the file is destined for a home cinema receiver rather than a phone, which will downmix at playback time anyway.
Is the MP2 to MKV converter free?
+
Yes — basic MP2 -> MKV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an MP2 file can I convert to MKV?
+
Free accounts: up to 100 MB per MP2 file. Premium: typically 1 GB per file, depending on the MP2 source type. Very large files get split into chunks server-side when the MKV format permits.
Will conversion change the content of my MP2?
+
Conversion preserves every piece of information that both MP2 and MKV can represent. Features the MKV format cannot store (vector data in raster output, formulas in plain-text output, embedded fonts in image output) are rasterized or stripped — the result page flags any feature loss explicitly.
Can I convert many MP2 files to MKV at once?
+
Yes — drop multiple MP2 files into the upload zone and they queue in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the MP2 to MKV converter work on phones / tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end without an app.
Which browsers does the MP2 to MKV converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses a plain `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers convert MP2 to MKV successfully.
Are my MP2 files kept private?
+
Yes — uploaded MP2 files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window. MP2 is extremely robust to bit errors and cheap to decode, which is why broadcast chains stayed on it long after MP3 arrived.
