      Our test: centre stamp vs tiled stamp

      Two looks on the same file

      We stamped a 6-page test PDF twice. First with one diagonal CONFIDENTIAL in the centre. Then with DRAFT repeated across each page.

      Autotext size fits the page
      25%default see-through level
      6 of 6pages stamped

      With Auto fit, the single stamp stretched across most of the page. The tiled stamp used smaller text in neat rows. At 25%, the text under the watermark stayed easy to read in both cases.

      Good to know: a text watermark shows ownership, but anyone with a full PDF editor can still remove it. For true protection, share a PDF turned into images or keep the original private.

      Right now the watermark supports English letters, numbers and common symbols. Letters from other alphabets are left out.

      Final thoughts

      A watermark tells readers what a document is before they read a word. DRAFT says it is not final. CONFIDENTIAL says it should not be shared. A name or brand says who owns it. This tool adds that message to every page in a few seconds. You pick one bold stamp or a pattern across the page.

      The default light setting keeps the page easy to read. You can watermark many files in one go, or only certain pages. Keep in mind that text watermarks are a signal, not a lock. Still, they work well for most daily needs. Your files are stamped on your own device and are never uploaded.
