Matroska Inspector

Inspect MKV, MKA, MKS, and verified WebM files to see bounded track, codec, language, flag, chapter, and attachment facts before extracting anything.

Choose an MKV, MKA, MKS, or WebM file up to 1 GB. The EBML header and container are validated before any tracks can be selected.

Native extraction limits

No stream is transcoded. Elementary video and audio outputs can require codec-specific headers or compatible software, while container-level timing, names, chapters, tags, and default or forced behavior are recorded in the manifest instead of embedded in every output.

Encrypted streams, unsafe attachments, malformed containers, arbitrary command options, remote URLs, payload previews, decryption, and DRM circumvention are not supported. Upload only media you have the right to process.

Matroska Inspector

Inspect verified MKV or WebM container metadata and enumerate tracks and attachments.

Input
One supported Matroska or WebM file.
Output
Container metadata, track details, and permitted native extractions.
Real limitations
The tool does not decrypt protected streams, decode every codec, repair damaged media, or promise playback compatibility.
Privacy and data handling
one supported Matroska or WebM file is uploaded to a compatible Convertr worker only after you start the operation. Processing is automated, and temporary source and result files are deleted automatically after processing rather than retained as permanent storage.

How to use this tool

  1. Choose one supported Matroska or WebM file and wait for the page to validate it.
  2. Set the available output or inspection options, then start processing.
  3. Review the reported result and download container metadata, track details, and permitted native extractions before the temporary link expires.

Common failure modes

Invalid EBML, truncated clusters, unsupported track data, or unsafe attachment names can stop inspection or extraction.

Useful example

Inspect a movie.mkv to identify its H.264 video, two audio tracks, subtitles, and chapter metadata.
