What a motion photo actually is
When motion capture is on, your phone saves a normal JPEG and then appends a few seconds of MP4 video to the end of the same file. Your phone's gallery knows the trick; nothing else does — so recipients get a still, editors get confused, and every photo eats 10-20 MB. This tool finds the video's byte boundary and splits the file — no re-encoding, original quality both sides.
FAQ
Which phones does this work for?
Samsung Galaxy motion photos and Google Pixel motion photos (MVIMG_*.jpg and *.MP.jpg both work). iPhone Live Photos are different — they're two separate files, not one — a Live Photo tool is on the workbench.
"No embedded video found"?
Then motion capture was off for that shot, or an app already stripped it (WhatsApp and most social apps do on upload). Only originals straight from the phone keep the motion part.
Why "photo only"?
Stripping the hidden video typically shrinks the file 60-80% — nice before emailing or archiving photos you'll never want the motion from.
