Conversor en línea MP4→MKV gratuito. Rápido, privado, sin registro.
If something is asking you for a MKV file and all you have is a MP4, this page is the fix. Drop in your MP4 file (a .mp4) and download a ready-to-use MKV file (a .mkv) — no software to install, no account to create, and no watermark on the output.
MP4 (H.264) is the most compatible video format in the world — it plays on virtually every device, browser and social platform.
MKV (Matroska) is a flexible open container that can hold almost any codec plus multiple audio tracks and subtitles, popular for archiving.
Most people convert MP4 to MKV for compatibility — a website, app or device insists on MKV, and MP4 simply won't open. MKV is widely supported, which makes it a dependable target. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.
It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.
Privacy is the default here. Your MP4 file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
