About the free video metadata remover
Video containers carry more than video. Alongside the encoded frames, an MP4 or MKV file stores descriptive tags: a title, a comment field, the name and version of the software that encoded the file, capture device identifiers, timestamps, and on phone footage sometimes the location where it was recorded. None of it is visible during playback, all of it travels with the file when you share it. This tool removes every one of those tags directly in your browser. The file never uploads anywhere, which is both the privacy point and the reason the tool has no usage limits.
The interesting part is how it removes them. Instead of re-encoding the video, which is slow and always costs quality, the tool remuxes: it copies the compressed video and audio streams byte for byte into a fresh container that simply has no metadata section. Every frame in the output is bit-identical to the original. That is why even long videos finish in seconds, and why the process works in browsers without WebCodecs support, since nothing is ever decoded.
Why clean your videos before publishing
Encoder tags reveal your editing software and workflow, device tags identify the camera or phone model, timestamps reveal when footage was actually captured, and location tags can reveal where. For journalists, sellers, and anyone posting footage of their home or workplace, that is information worth controlling. Freelancers and agencies also strip metadata for professional reasons: a client deliverable that quietly announces which tool exported it looks less polished than a clean file. If you want to see what a file is carrying before cleaning it, the free video metadata viewer shows every tag, and this tool lists what it found before you commit.
What removal does and does not cover
Remuxing removes everything stored at the container level, which is where descriptive metadata lives. It does not alter the encoded frames themselves, because they are copied untouched; nothing visible in the picture, like a timestamp burned into the corner by a dashcam, is affected. Technical parameters that players need, such as resolution, frame rate, and codec configuration, necessarily remain, since the video would not play without them. In short: everything about the file's origin story goes, everything required for playback stays.
Formats, limits, and the photo equivalent
The tool accepts MP4, M4V, MOV, WebM, and MKV. MP4 and MOV come back as MP4, WebM and MKV come back as WebM, and because the streams are copied rather than transcoded, the output plays everywhere the original did. There are no file size or usage limits; your device does the work, and files up to around 2 GB remux reliably. Photos deserve the same treatment before publishing: the free image metadata remover strips EXIF and GPS data from images with the same zero-loss approach. And if the cleaned footage itself needs work, our premium AI Video Upscaler sharpens and enlarges it up to 4K.
