Smart document tools

Extraction, checking and question-answering for when converting a file is not enough.

A watermark marks a document as yours, or marks it as not final. Doclium stamps your text diagonally across every page as real page content, not as an annotation a reader can delete in two clicks.

🔒 Never used for AI training: delete a document and it is gone from the server.
⚡ No watermarks: on any tool, including the free tier.
↩ Undo: step back through your last 10 edits.

How to add a watermark to a PDF

  1. 1Upload the PDF you want to watermark.
  2. 2Type the text and pick a colour and strength.
  3. 3Download the watermarked document.

Questions people ask

Can the watermark be removed?

Not by clicking it. It is drawn into the page rather than added as an annotation, which readers can delete outright. Anyone determined enough can edit any PDF, but this survives ordinary use.

Will it cover my text?

It is drawn semi-transparent, so the page stays readable. You choose the strength.

Does Doclium add its own watermark?

No. The only text on your document is yours.
