OGG to MKV Conversion FAQ
Is the OGG to MKV converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
How big an OGG file can I convert to MKV?
+
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 convert many OGG files to MKV 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.
Does the OGG 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 OGG 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 OGG to MKV successfully.
Are my OGG files kept private?
+
Yes. Uploaded OGG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MKV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy. OGG Vorbis beats MP3 at equal bitrate and carries no licensing cost, which is why game engines and open-source software adopted it wholesale.
What if the MKV download does not start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download you can re-trigger from the result page without re-uploading the OGG.
How long does OGG to MKV conversion take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame. MKV is the archival container of choice because it stores unlimited audio tracks, soft subtitles, chapter markers and cover art in one file. MKV has almost no native hardware support — phones, browsers and TVs usually need VLC or a remux before they will play it.
Do I need to install software to convert OGG to MKV?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload your OGG, wait, download the MKV.
Can I convert OGG to MKV without an account?
+
Yes for one-off conversions. Sign up free for batch history, server-side file storage, and higher conversion limits. Premium adds parallel workers, bigger file caps, and removes ads.
