Does cleaning reduce video or audio quality?

No. This uses ffmpeg's stream-copy mode (-c copy), which copies the encoded video and audio data through unchanged — only the surrounding container metadata is removed.

Does this remove C2PA data from a video?

Often, as a side effect: ffmpeg's remux process typically does not carry through boxes it doesn't recognize, which commonly include C2PA manifests. The before/after report checks this directly rather than assuming it, since it isn't guaranteed for every container/encoder combination.

Video Metadata Cleaner

Temporary server processing

Strip container-level metadata from a video without re-encoding.

MP4, MOV, WebM, or MKV — container metadata stripped without re-encoding.

How it works

1Choose or drag in an MP4, MOV, WebM, or MKV file.
2On an isolated, randomly-named temporary server file, ffmpeg remuxes the video with -map_metadata -1 -c copy — this clears container-level metadata (title, GPS/location tags, creation time, encoder strings, chapters) using a stream copy, so the actual video and audio data is never re-encoded.
3The cleaned file is returned for download and the temporary copy is deleted immediately. We then re-check both the original and cleaned file to show an honest before/after comparison, rather than assuming the result.

Privacy

Your video is written to an isolated temp file with a randomized name, processed, and deleted immediately after — on success or failure. It is never permanently stored or made public.

Limitations

Because this uses a stream copy (no re-encoding), video/audio quality is fully preserved, but this also means it can't remove metadata embedded inside the encoded stream itself. It also cannot guarantee removal of every vendor-specific private box some encoders write — ffmpeg only clears the metadata tags and chapters it recognizes.
