Quick answer

In an MKV, metadata lives in Segment Info (Title, MuxingApp, WritingApp, DateUTC) and in the Tags element. To remove it, open the file in MetaRemove, review the list and download the clean copy, with no re-encoding.

Where this metadata lives in the file

Real technical names, as ExifTool or MediaInfo show them. Which fields exist depends on the device and app.

Field Where it lives Example
Title Segment Info → Title home_recording_2026 Removed
Apps used MuxingApp · WritingApp libebml v1.4 · HandBrake 1.8 Removed
Mux date Segment Info → DateUTC 2026-03-14 18:42 Removed
Free-form tags Tags → SimpleTag ENCODER, COMMENT, CREATION_TIME Removed
Video, audio and subtitles Tracks + Clusters HEVC · Opus · SRT Kept

Why MKV carries so much information

Matroska is a flexible container: it accepts free-form tags, per-track names and attachments. Apps like HandBrake, OBS and mkvmerge record their own name and the mux date; cameras and editors may add CREATION_TIME, COMMENT or titles with names of people and places.

Attachments deserve attention: JPG cover art inside an MKV can carry its own EXIF, with GPS and camera. Use the free check to see whether your file has attachments.

Why not edit the MKV by hand

Matroska editors mean installing software, understanding the file structure and repeating the process for title, tags and mux data, one file at a time. MetaRemove cleans in the browser, in batches, and shows before and after.
