Clean boxes while preserving offsets
MP4 files contain structural boxes. This tool replaces supported udta, meta and ilst metadata boxes with same-size free boxes, leaving all media byte offsets unchanged.
It does not re-encode video or audio. Open and play the downloaded copy before publishing.

Why MP4 offsets must stay fixed
MP4 index tables refer to byte positions of audio and video samples. Replacing supported metadata with same-size free boxes leaves those positions unchanged.

FAQ
Ofte stillede spørgsmål
Is the video uploaded?
No. It is processed on your device.
Is video re-encoded?
No. Audio and video payload stays at the same byte offsets.
Does it remove all MP4 metadata?
No. Only supported boxes; some UUID or track-specific data can remain.
Should I test playback?
Yes. Play the downloaded copy and verify sound, picture and duration.
Can it remove a video watermark?
No. A watermark in a frame is not an MP4 metadata box.
