Choose a supported clip
Select an MP4, MOV or WebM up to 64 MiB. The file extension alone does not guarantee that its codecs and tracks are supported.

AT A GLANCE
Can I remove video metadata without re-encoding?
Quiet Media Tools copies supported video and audio tracks from MP4, MOV and WebM files without re-encoding them. It removes supported descriptive container metadata, rebuilds and checks the container, and offers a separate download. Processing runs in your browser without uploading the video.

- MP4, MOV or WebM; codec support varies
- Limit
- 64 MiB input; 96 MiB output
- Processing
- Local stream copy; no new compression pass
Subtitles, chapters, attached artwork and timed-data tracks are omitted. Required playback data and metadata inside encoded packets can remain. Read the method and limits.

How to remove video metadata
Copy the tracks locally
On first use, your browser downloads about 31 MiB of processing software. It inspects your file and copies supported encoded tracks without uploading them.
Check playback before sharing
Download the checked copy and play it from beginning to end. Confirm picture, sound and orientation, and keep the original for subtitles or chapters.
THE REMOVAL SCOPE
Video tags and playback data have different jobs.
| Video information | What the cleaner does |
|---|---|
| Titles, descriptions and comments | Removes supported descriptive container metadata. This does not edit text burned into the video. |
| Location and date information | Removes supported optional container fields. Technical timestamps needed for playback are retained. |
| Embedded credential containers | Scrubs supported optional metadata boxes, including supported embedded C2PA structures. External records may remain. |
| Video and audio tracks | Copies supported encoded tracks without a new compression pass. The container is rebuilt and verified. |
| Subtitles, artwork, chapters and timed data | Omitted from the new file. Subtitles already burned into the picture remain visible. |
| Codec and playback configuration | Retained where required. Container, language, encoder, vendor or handler information may still be present. |
The original is not overwritten. Read the processing method and verification limits or see how file privacy works.
WHAT A CLEAN COPY MEANS
A clip with a title and subtitle track
Illustrative example—not an analysis of your file.
Before cleaning
An MP4 may include a title, descriptive creation tags, chapter markers and a separate subtitle track.
After cleaning
Supported video and audio tracks are copied into a cleaned container. Supported descriptive tags, chapters and the subtitle track are omitted; captions already in the frames remain.
What to check in a cleaned video
- Play the downloaded copy and check picture, audio, orientation and timing.
- Inspect the downloaded container with a media-information tool if you need an independent metadata review.
- Remember that voices, visible details, invisible watermarks, encoded-packet metadata and external records are outside container-tag removal.
KNOW WHAT CHANGES
Video metadata
questions, answered.
Does this reduce video quality?
Supported encoded tracks are copied without re-encoding, so there is no new compression pass. The container changes; the complete output file is not byte-identical to the original.
Can I keep subtitles and chapters?
No. This cleaner omits subtitle and timed-data tracks, attached cover art and chapters. Keep your source file if those features matter.
Why might an MP4 or MOV fail?
These are container formats that can hold many codecs and track layouts. Unsupported or encrypted audio/video tracks, damaged containers, size limits or failed output checks can prevent a download.
Is all identifying information removed?
No. The tool targets supported descriptive container metadata. Required playback information and identifying information in the content, encoded packets or external systems can remain.
