MKV Playback FAQ
How do I play a MKV file in my browser?
+
Drop your MKV file onto the player. When your browser can decode MKV, it plays right away with no plugin; when it cannot, the page says so and links to a converter.
Which video and audio codecs inside MKV are supported?
+
The player uses your browser's native decoders, so common MKV codecs (H.264/AVC, and where the browser supports it H.265/HEVC, VP9, or AV1) play directly.
Does the MKV player support multiple audio tracks?
+
No. The player has no audio track selector; it plays the track your browser picks, usually the first one.
Can I load subtitles with a MKV video?
+
No. The player has no option to load SRT or VTT subtitle files.
Why does my MKV video play but have no sound?
+
Usually the MKV file uses an audio codec your browser can't decode (e.g. certain AC-3/DTS tracks). Convert the audio track or the whole MKV to a web-friendly codec.
Is my MKV file uploaded anywhere?
+
No. Your MKV file is decoded locally in the browser and never leaves your device.
Does the MKV player work on mobile?
+
It works in mobile browsers that can decode MKV and the codecs inside it. Where a browser cannot, the page says so and links to a converter.
Can I seek and scrub through a large MKV file smoothly?
+
Yes. MKV stores seek indexes, so the player can jump to any point quickly even in long, high-bitrate files.
Can I adjust playback speed for MKV?
+
The player has no playback speed control of its own. Your MKV file is never changed.
My MKV file won't play at all — what should I check?
+
Confirm the MKV isn't using an exotic codec your browser lacks. Converting the MKV to H.264/AAC MP4 maximizes compatibility.
Do I need an account or app to play MKV?
+
No. The MKV player is free, installs nothing, and works immediately in the browser.
Can I convert or compress MKV here?
+
Yes. After previewing you can compress, trim, or convert your MKV to MP4, MKV, WebM, MOV, and more.
