Upload your GIF file using the picker above and the converter detects the source type and runs the GIF -> MKV pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Is the GIF to MKV converter free?
+
Yes — basic GIF -> MKV conversion is free with no registration. Pro adds higher per-file size caps, more parallel batch workers, removes ads, and unlocks API access for MKV output.
How big a GIF file can I convert to MKV?
+
Free accounts: up to 100 MB per GIF file. Pro: typically 1 GB per file, depending on the GIF type. Very large files are split into chunks server-side when the MKV format allows.
Will conversion change the content of my GIF?
+
Conversion preserves all information that both GIF and MKV can represent. Format-specific features that MKV does not support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
Can I convert many GIF files to MKV at once?
+
Yes — drop multiple GIF files into the upload zone and they queue in parallel. Pro has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the GIF 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.
Which browsers does the GIF to MKV converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
Are my GIF files kept private?
+
Yes — uploaded GIF 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 GIF.
How long does GIF to MKV conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. Server-side pipeline runs on dedicated workers — your laptop CPU is not the bottleneck.
Do I need to install software to convert GIF to MKV?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload, wait, download.
Can I convert GIF to MKV without an account?
+
Yes for one-off conversions. Sign up free for batch history, server-side file storage, and higher conversion limits. Pro adds parallel workers, bigger file caps, and removes ads.
