MKV is a flexible, open-source multimedia container format. It can hold video, audio, subtitles, chapters, and metadata in a single file. MKV is widely used for high-definition movies and streaming, supporting multiple audio tracks and subtitle languages.
WEBM is an open, royalty-free video format designed for web use. It uses VP8 or VP9 for video and Opus or Vorbis for audio. WEBM is supported by all major browsers and is optimized for fast loading and efficient streaming in HTML5 environments.
Convert your .mkv files to .webm right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your MKV files into WEBM in just a couple of clicks. No registration, no limits — and it’s 100% free.
