A watermark is a quick way to mark a document as a draft, confidential, or attributed to you before you share it — without editing the underlying content.
Filovo lets you type any text, then stamps it diagonally in a repeating pattern across every page and rebuilds the file as a new, watermarked PDF you can download immediately.
