Why Luleit's PDF Watermark Tool is Different

Frequently Asked Questions

Where does my PDF go when I add a watermark?+

Nowhere. The watermarking happens in your browser using JavaScript — your PDF never touches our servers, never gets uploaded, never gets stored. Once you close the tab, the file is gone from memory; we have no copy. There is nothing for anyone to subpoena, breach, or sell.

Is this watermark tool really free, with no catch?+

Yes — no signup, no email required, no watermarks, no page limits, no daily quota, and no upsell for a paid tier. The tool runs entirely in your browser using free, open-source JavaScript libraries, so we have no server costs to recover. Your privacy IS the business model: we collect nothing because we have no use for it.

Can the watermark be removed by the recipient?+

It can be — text watermarks are added as a layer on top of the original content and a determined recipient with the right tool can edit them out. For sensitive documents, combine watermarking with the Protect PDF tool to discourage casual editing.
