How to remove metadata from a video
A phone video carries location, device and date. How to strip them before sharing the file.
Published by AnonShot · Updated
The short answer
A video shot on a phone carries the same sensitive information as a photo — location, device model, date — just stored differently. AnonShot accepts short videos up to 150 MB and applies the same protections as it does to an image.
Where video metadata hides
An MP4 or MOV file does not use the EXIF format that photos use. It is divided into containers called atoms, and descriptive information sits in some of them.
The most problematic atom holds the geographic coordinates of the shooting location. Add to that the device model, the OS version, the date and sometimes the name of the editing software.
What sets a video apart from a photo
Three differences change how you should handle the file.
- Size: a minute of high-definition footage easily exceeds a messaging app's attachment limit, which pushes you towards a link.
- Duration: a video shows movement, voices, a whole environment. It reveals far more than a single image, metadata aside.
- Audio: a background conversation is often the most serious leak, and no metadata clean-up touches it.
Clean-up methods
exiftool handles video containers the same way it handles images, with the same global removal command. ffmpeg can also copy the streams without the metadata, with no re-encoding and no quality loss.
On mobile, no built-in option removes this information cleanly, and most gallery apps do not even display it.
Sharing without installing a tool
Drop the video onto AnonShot from your browser: it is accepted up to 150 MB in MP4, WebM or MOV, and gets password protection and burn-after-read just like a photo. It is the shortest route when the file has to leave as a link rather than an attachment anyway.
Frequently asked questions
- How large a video can I send?
- Up to 150 MB per video, in MP4, WebM and MOV.
- Does a video contain my location?
- Yes, if geotagging was on while filming. The coordinates are written into the container, not into an EXIF block.
- Is the audio handled?
- Metadata clean-up does not touch the audio track. Listen back before sharing: a background conversation often reveals more than any metadata.
