Remove metadata from MP4 (.mp4)
Step-by-step: what metadata MP4 contains, how ExifSweep removes it, and what gets preserved.
What MP4 typically leaks
- creation_time (down to the second)
- GPS via com.apple.quicktime.location.ISO6709
- Camera make/model in moov atom
- Software/encoder string
- Title, artist, album (rare but possible)
Why this matters
MP4 is the universal video container. Apple, GoPro, Android all leak metadata here.
How ExifSweep cleans it
FFmpeg.wasm runs in your browser with `-c copy -map_metadata -1`. No re-encode means no quality loss and processing in seconds for any size.
What we preserve
All streams (video, audio, subtitles); codec settings; all visual quality.
Try it on your .mp4 file
Free, in your browser, never uploaded.
