M4A 에 MKV 변환 FAQ
How do I convert a M4A file to MKV?
+
Upload your M4A file using the picker above and the converter detects the source type and runs the M4A -> MKV pipeline. The result downloads automatically when conversion completes; no account is needed for one-off conversions.
Is the M4A to MKV converter free?
+
Yes — basic M4A -> MKV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a M4A file can I convert to MKV?
+
Free accounts: up to 100 MB per M4A file. Premium: typically 1 GB per file, depending on the M4A source type. Very large files get split into chunks server-side when the MKV format permits.
Will conversion change the content of my M4A?
+
Conversion preserves every piece of information that both M4A 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 M4A files to MKV at once?
+
Yes — drop multiple M4A 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 M4A 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 M4A 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 M4A to MKV successfully.
Are my M4A files kept private?
+
Yes — uploaded M4A files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
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 M4A.
How long does M4A to MKV conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. The server-side pipeline runs on dedicated workers — your laptop CPU is not the bottleneck.
Do I need to install software to convert M4A to MKV?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload your M4A, wait, download the MKV.
Can I convert M4A 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.
