MKV & WebM Metadata Remover: Clean Titles and Tags
A Matroska or WebM file stores a title, a muxing and writing application, a creation date, a unique ID, track names, tags, and sometimes attached cover images, in several separate places. Choose a file, see each field, and download a cleaned copy whose picture and sound are untouched.

What happens locally
A focused cleaner, not a black box.
Same size, same offsets, same video
Removed elements are replaced in place by empty Void elements of the same length, so the file size and every index position stay the same and the video and audio data are never touched. Checksums that cover edited elements are recalculated.
Subtitles and chapters stay
Fonts and other attachments needed to display subtitles, and chapters, are kept and reported instead of being removed, so the file plays and navigates exactly as before.
Important limit
This removes container metadata, not picture or sound. Anything visible or audible stays in the video, as do subtitles, chapter titles, and the codec-level data inside the streams. Files with streaming (unknown-size) elements, such as live recordings, are not supported; remux them first. One file at a time, up to 100 MB. Verification is structural; the result was not played back.
Questions & boundaries
Know exactly what the clean copy means.
File formats are messy. These answers describe the supported behavior of this version—not a promise that every trace everywhere has disappeared.
01How do I remove metadata from an MKV file?+
Choose the file on this page. It lists the title, applications, dates, track names, tags, and attached images it finds. Keep the boxes you want removed ticked, click Clean, and download the new copy. Your original is not changed.
02Does it re-encode the video?+
No. Only metadata elements are replaced in place. The video and audio data are byte-identical, and the file size does not change.
03What exactly is removed?+
The segment title, muxing application, writing application, creation date, segment UID, original file name, track names, tags such as ARTIST, ENCODER and statistics, and attached images such as cover art.
04Are WebM files supported?+
Yes. WebM uses the same container as Matroska, and the cleaned copy keeps the .webm extension.
05Why are chapters and fonts not removed?+
Chapters are how you navigate the file, and fonts are needed to draw styled subtitles. Removing them would change how the file plays, so they are reported and left alone.
06Is my file uploaded?+
No. The file is processed inside your browser. You can confirm this in the Network panel of your browser's developer tools.
