DivX to MKV Conversion FAQ
Is the DivX 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.
My DivX footage shows comb lines on movement — will that carry into the MKV?
+
Yes. DivX content is often interlaced, because the format comes from the broadcast and DVD era, and this converter has no deinterlace option, so the combing carries into the MKV. If it matters, deinterlace the DivX first in a desktop tool such as HandBrake or ffmpeg (the yadif filter). DivX names a codec rather than a container — an MPEG-4 Part 2 implementation that made ripping a DVD to a single CD possible around 1999.
My DivX recordings are split into numbered parts — does MKV have the same limit?
+
No, and that is one of the better reasons to move. The DivX container has a practical single-file ceiling that long or high-bitrate recordings run straight into, which is exactly why old captures arrive as part1, part2, part3. MKV has no equivalent limit, so the pieces can be rejoined into one continuous file. DivX needs roughly twice the bitrate of H.264 for the same quality and has no path to HDR, 10-bit colour or resolutions beyond 1080p.
Can I add selectable subtitles once the file is MKV?
+
Yes. DivX has no usable soft-subtitle track, so subtitles for DivX content had to be burned into the picture or shipped as a separate sidecar file. MKV carries subtitles as their own selectable stream, so after conversion you can attach an SRT track the viewer can switch on, switch off or restyle. 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.
Does MKV support chapter markers that DivX did not?
+
It does. MKV stores chapters as container metadata, so a long recording can be navigated by section instead of by scrubbing a progress bar. DivX has nowhere to put that information, so the converted MKV starts with no chapters; add markers afterwards with a tool such as MKVToolNix or ffmpeg. MKV is the archival container of choice because it stores unlimited audio tracks, soft subtitles, chapter markers and cover art in one file.
Is MKV a container or a codec, and does that change what I get back?
+
It changes what to expect from the output file. One side of this conversion names an encoding rather than a wrapper, so what comes back is that bitstream inside whichever container suits it best — normally MP4 or MKV. The extension reflects the container; the codec is what actually determined the file size and where it will play. DivX content is MPEG-4 Part 2 video, usually wrapped in AVI, with MP3 or AC-3 audio alongside it.
How big a DivX 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 DivX 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 DivX to MKV converter work on phones and 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 DivX 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.
