Why remove MKV metadata?
MKV files can carry muxing, encoder, and user tags that expose sources or workflows. Cleaning removes them while preserving streams.
Share encodes anonymously
Remove muxing app and encoder tags before distributing MKVs.
Deliver clean subtitles
Strip chapter titles and comments while keeping subtitle tracks intact.
Remove embedded artwork
Delete attachments like cover art that may reveal origin or branding.
Secure MKV cleaning
We scrub MKV tags and attachments while preserving streams and chapters, then delete the temporary file after processing.
Upload your MKV
Select an MKV/Matroska file. Uploads are encrypted and not stored after processing.
Strip tags and attachments
We remove segment/track/chapter tags, encoder notes, comments, and attached images or fonts.
Preserve streams and HDR
Video, audio, subtitles, HDR flags, and chapters stay intact; only metadata is cleared.
Download & purge
Download the cleaned MKV; the temporary copy is wiped immediately.
What MKV metadata do we remove?
We clear Matroska tags that can reveal source, editor, or user info while keeping streams unchanged.
- Segment title, muxing app, writing app, and date tags
- Track-level title, language, encoder, and comment fields
- Chapter titles, comments, and tag elements
- Attachments such as cover art or embedded fonts
- Custom tags added by remux tools or encoders
- User-defined key/value pairs stored in Matroska tags
- Optional XMP packets embedded within MKV
- Thumbnails or preview images saved as attachments
What Matroska tags reveal about an encode
MKV's tag model is the most expressive of any video container — every segment, track, and chapter can carry its own set of key/value tags plus nested sub-tags. That flexibility is why MKV is the de facto distribution format for archival, anime, and HDR rips, and it is also why MKVs accumulate long trails of muxer and encoder fingerprints. A typical MKV includes a 'muxing app' (MKVToolNix with version), a 'writing app' (HandBrake or x264/x265 with full command-line options), per-track encoder settings, chapter titles that often reveal the source (DVD/Blu-ray title naming conventions, release group signatures), and language/forced-subtitle flags that hint at the origin region.
Attached cover art, fonts, and subtitle files ride alongside the stream as EBML attachments — those attachments can themselves contain metadata (font authors, subtitle styling notes) that point back to the creator. Cleaning removes every Tags element, every Tag sub-element, every Attachment, and resets segment/track titles to empty while leaving the video, audio, subtitle tracks, HDR flags, chapter timing, and seek index intact.
