Strip GPS, capture date, device and every other identifying tag out of an MP4 or MOV — without uploading the file anywhere, and without touching a single pixel of the video itself.
If you've ever opened a clip from your phone's camera roll in a desktop video player, you may have spotted a small detail that says exactly where you filmed it — sometimes down to the street. That data lives in the MP4 container alongside the picture, recorded automatically the moment you hit record. The same goes for the exact date and time of filming, the model of your phone, the version of its operating system, and any editing app that's touched the file since.
Most of that data is innocuous most of the time. Some of the time it isn't: you're sending footage from your home, a video about a sensitive situation, a clip a source asked you to share. The problem with the usual advice — "use a tool to strip the metadata" — is that almost every such tool wants you to upload the file first, which means the metadata reaches their server before it's removed. Zimblu cleans the file before it has the chance to travel anywhere.
udta or QuickTime location tags. Removed entirely.Before the strip runs, Zimblu shows you every item it found in your file by name — so you can see what was actually leaking, not a generic claim. If your file happens to already be clean, the tool says so honestly and doesn't pretend it found something it didn't.
Modern phones embed a surprising amount of identifying information in the MP4 container itself, separate from the picture: the exact GPS coordinates where the clip was filmed, the capture date down to the second, the device model and OS version, and the editing software that touched it. Some of that gets sent along when you share the file directly — by message, by email, or by uploading it to a site that doesn't bother to strip it.
In your browser, on your own device. Zimblu reads the file's container boxes locally, lists what it finds, then rewrites a fresh container with the picture and sound streams copied across and every identifying block dropped. Your video does not reach a server at any point — if you turn off your Wi-Fi after the page loads, the tool still works.
No. The video and audio streams are copied byte-for-byte into the new container — same pixels, same sound, same bitrate. Only the surrounding metadata is rewritten. That's also why the strip is almost instant: in our tests, a 5-second 1080p clip cleans in under 20 milliseconds because nothing has to be decoded or re-encoded.
Containers also carry their own creation and modification times in the header (separate from the EXIF-style tags). Zimblu replaces those with zeros — the standard MP4 way of saying "no information" — so the cleaned file doesn't leak when it was filmed nor when you cleaned it.
Yes. The output is a standard MP4 with H.264 or HEVC video and AAC audio, which is what your phone, QuickTime, VLC, WhatsApp and every modern player expect. We've tested the output through Apple's own AVFoundation media stack and through ffmpeg's decoder — both play it cleanly.
