AAC à MKV FAQ sur la conversion
How do I convert a AAC file to MKV?
+
Upload your AAC file using the picker above and the converter detects the source type and runs the AAC -> MKV pipeline. The result downloads automatically when conversion completes; no account is needed for one-off conversions.
Is the AAC to MKV converter free?
+
Yes — basic AAC -> MKV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a AAC file can I convert to MKV?
+
Free accounts: up to 100 MB per AAC file. Premium: typically 1 GB per file, depending on the AAC source type. Very large files get split into chunks server-side when the MKV format permits.
Will conversion change the content of my AAC?
+
Conversion preserves every piece of information that both AAC 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 AAC files to MKV at once?
+
Yes — drop multiple AAC 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 AAC 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 AAC 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 AAC to MKV successfully.
Are my AAC files kept private?
+
Yes — uploaded AAC 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 AAC.
How long does AAC 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 AAC to MKV?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload your AAC, wait, download the MKV.
Can I convert AAC 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.
Le format MKV (Matroska) peut contenir un nombre illimité de pistes vidéo, audio et de sous-titres dans un seul fichier, ce qui est idéal pour les films.
