Anything that uniquely identifies this version. Stays inside the file you download — we never see it.

Tagged files include the title, creator, and work ID you enter, plus a UTC timestamp. Mivia Sign is a peace-of-mind tool — your signature proves what was tagged and when, not who tagged it. Account-backed identity proofs land in a future release.

Signed and downloaded

Your watermarked file has been saved to your downloads. The original audio is unchanged perceptually — only an inaudible signature has been embedded.

Could not sign

Something went wrong. Please try a different file.

Mivia Sign is a free signer and verifier for the Mivia Sign watermark format. We never store your audio — files are deleted immediately after processing.
