What this tool does

Watermark a PDF
Lays text or an image over every page — a draft notice, a company mark, a recipient's name. It sits on top as a new layer; the text underneath stays selectable and can be removed again by editing the PDF.

When you need this

  • A draft contract should be clearly marked as not yet valid.
  • A copy of an ID sent to a landlord should say what it may be used for.

Frequently asked questions

What files can I use here?

Reads PDF. One file at a time.

What do I get back?

You get PDF.

Does the file lose quality?

The pixels and the text are left alone. Only the structure around them changes.

When does it not work?

Password-protected files cannot be opened.

Does the text stay searchable?

Yes, and compressing keeps it that way too: by default only the embedded photos are recompressed, while text, fonts and layout stay untouched. Merging, splitting and adding images move the pages as they are. Only the second compression method redraws every page as an image — then the text becomes part of the picture, and the tool says so before you start.

Can password-protected PDFs be opened?

No. A PDF locked with a password cannot be read in the browser, and the tool says so rather than producing an empty document. Remove the protection in the program that created the file first.
