Video Metadata Cleaner
Online
Strip hidden metadata from MP4, MOV, and WebM videos — Instagram Reels, TikToks, and YouTube Shorts included. The cleaner runs entirely in your browser using ffmpeg.wasm; videos never leave your device.
What we remove from your videos
- C2PA “Made with AI” tags embedded by Adobe Firefly, Photoshop, ChatGPT video tools, and Runway.
- MP4
udtaandmetaatoms — creator IDs, GPS coordinates, camera model, encoder name. - XMP edit history from Adobe suite (which clips were trimmed, filters applied, project metadata).
- Chapter metadata, language tags, and handler names that leak the recording app.
- Platform watermarks stored in custom user atoms (some TikTok and Instagram downloads).
How it works (no quality loss)
We don’t re-encode the video. A small ffmpeg.wasm engine in your browser remuxes the container with -c copy -map_metadata -1 -map_chapters -1— same pixels, same audio, same encoding, just the metadata atoms dropped. The first time you drop a video the engine downloads (~30 MB, one-time, cached); after that it’s instant.
What this does not remove
Pixel-level watermarks (Google SynthID-for-video, baked-in TikTok branding) survive remuxing because pixels are untouched. Visible on-screen watermarks stay where they are. Some platforms also fingerprint videos by content — that’s separate from metadata.
Frequently asked.
Will it remove the Made with AI label on Instagram?+
Removing the C2PA content credential from the file removes one signal Meta uses to flag AI-generated video. Meta also reads user disclosures on upload and may use other detection methods, so we can't promise the label never appears — only that the embedded file signal is gone. See our blog post on removing the Made with AI label for full details.
What's the maximum video size?+
500 MB per video. Larger files start hitting browser memory limits, especially on phones. For very large videos, a desktop tool that doesn't run in-browser is usually the right choice.
Does cleaning re-encode the video?+
No. We remux the container (-c copy in ffmpeg terms), which means the audio and video streams are bit-for-bit identical to the input. The output is exactly as sharp as the original — no quality loss, no re-encoding artifacts.
Do you upload my video anywhere?+
Never. The entire cleaning pipeline runs in your browser via WebAssembly. Open dev tools and watch the Network tab — no video data is ever uploaded. Disconnect from the internet after the page loads and the cleaner still works.
Which formats are supported?+
MP4, MOV, and WebM. These cover ~99% of social-media video. For other containers (MKV, AVI) you'd need a desktop ffmpeg install.
