Is Remove metadata free? Is there a watermark?

Yes — Remove metadata is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Remove metadata runs entirely in your browser with WebAssembly, so your MP4, MOV, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Remove metadata accepts MP4, MOV, MKV and gives you back a MP4 file. Actual codec support depends on what the bundled engine or browser decoder can read.

Does Remove metadata change my original file?

No. It never touches your original — Remove metadata creates a brand-new MP4 file to download and leaves the source on your device untouched.

Remove metadata

Disable global metadata mapping while copying compatible audio and video streams into a fast-start MP4. This does not guarantee removal of every stream field or private detail.

Runs entirely in your browser. Your file is never uploaded — no watermark, no account.

Best for: Reducing copied container metadata before ordinary sharing when the picture and audio streams should remain unchanged.
Input → output: MP4, MOV, or MKV streams are copied into a fast-start MP4 while global metadata mapping is disabled. No picture or sound re-encode is requested.
Quality tip: Use a compatible H.264/AAC source. For sensitive sharing, inspect container and stream fields with an independent metadata tool afterward.
Know before running: This does not guarantee forensic erasure of every stream field, chapter, attachment, side datum, platform record, visible watermark, or information contained in the pixels themselves.
Next step: Compress video if the verified sharing copy must also meet a smaller size limit.

How to use Remove metadata

1
Choose your file. Drop a supported MP4, MOV, MKV file into the tool, or click to select one. It stays on your device — nothing is uploaded.
2
Run locally. Press Run to begin. The first processing run loads the browser engine before local processing begins.
3
Download. Review the result, then download the finished file from your browser with no watermark.
