Do my files get uploaded to your servers?

No. The browser reads the MP3 locally, fills the form from the ID3 tag, and writes a new tag in the same tab. This tool has no server endpoint, so there is nowhere for an upload to go.

Is there a cost, a sign-up or a watermark?

None of the three. Saving tags never touches your credits, and the output is a normal MP3 with the fields you typed — no extra audio and no watermark.

Can I tag WAV, M4A or FLAC?

Not here. This page writes ID3v2, which belongs on MP3. Convert those files first, then tag the MP3.

What happens to tags I do not fill in?

The writer replaces the existing ID3 tag with the form. Empty fields are omitted, so a blank title removes the old title. We prefill the form from tags we can read so you are not starting from scratch.
