Can a phone's motion photo hide a short video inside the JPEG file?
Yes. Some phones attach a short clip or extra pictures after the end of the main JPEG image, invisible in normal viewers. The tool reports 'Data after the end of the image' with its size in bytes, and removing it drops the attached video along with it.
How can an image file carry a video?
A JPEG file ends with a special marker that says 'the image ends here'. Viewers stop reading at that point. Some phones take advantage of that: they write the full image, then append after the end marker a short clip the camera captured just before and after you pressed the shutter. That is the idea behind live or motion photos on some devices. An ordinary viewer sees a photo; the phone's gallery app knows to play the clip.
In a similar way, some phones store extra pictures in the same file, such as a depth version or a different resolution, indexed by a segment called MPF.
Why this matters to a seller
- Privacy: the clip captures the moments before and after the shot. Maybe your voice as you talk, your hand arranging the product, or part of the room that never made the final frame.
- Size: an ordinary-looking photo can be heavier than expected because it holds a video.
- Sending as a document: when you send the file as it is, the clip goes with it to anyone who knows how to pull it out.
How to spot it
- Open the photo in the Image metadata inspector and remover tool.
- In the detected list, look for 'Data after the end of the image'. If present, it shows with its size in bytes.
- If the size is large, hundreds of kilobytes or more, it is most likely a video or extra pictures, not a few stray bytes.
- Look for 'MPF multi-picture index' as well, a sign of extra pictures inside the file.
The tool does not play or extract the clip; it tells you it is there and how big it is. That is enough to decide.
What removal does
Press 'Remove metadata' and the tool copies the image up to its end marker and nothing after it, so the clip is gone. The MPF segment is removed too. Extra pictures in MPF files are removed only when they sit after the end of the main image, which is where they normally live. The main image itself does not change, the pixel check confirms it, and the size line shows how much smaller the file got. In this particular case the difference can be large indeed, unlike removing EXIF alone.
Before you remove it
If you like the clip and want it, keep the original file on your phone and post only the clean copy. Once removed, the clip cannot be recovered from the clean copy. And if the photo is HEIC rather than JPEG, the tool does not support it at all.
Common questions
Does every file with 'Data after the end of the image' hold a video?
Not necessarily. Some programs leave a few extra bytes behind. The size is the clue: a few bytes is one thing, hundreds of kilobytes another.
Does the tool remove the motion from animated WebP images?
No. Animation data in WebP is part of the image itself; the tool leaves it and lists it.
Is the file uploaded to inspect the clip?
No. Inspection and removal happen inside your browser.
