Yes. Choose diagonal placement to add the classic diagonal watermark that runs across each page of your PDF. A diagonal, semi-transparent mark spans the whole page and is harder to crop out, which makes it the most effective choice for labelling documents.

Yes. By default the watermark is applied to every page of the document, so the entire file is consistently branded or labelled. If you only need it on certain pages, you can choose specific pages or a page range instead before applying the watermark.

A watermark is a visual deterrent and a branding mark, not a security lock. It discourages casual resharing and clearly signals ownership or draft status, but it does not encrypt the file or block copying. For genuine access control, combine a watermark with password protection on the PDF.

Around 20-40% opacity usually works best. That range keeps the watermark clearly visible while still letting the underlying text be read comfortably. Go higher if you want a bolder, more prominent stamp, or lower for subtle branding that stays out of the way of the content.

Yes. You can upload an image such as a company logo and place it as the watermark instead of, or alongside, text. Adjust its size, position, and opacity so it brands the page without covering important content. Transparent PNG logos tend to look cleanest over text.

Yes. The watermark is applied entirely in your browser, so your PDF is never uploaded to a server and nothing is stored online. This makes it safe to brand or label confidential documents like proposals and contracts without exposing them to a third party.

Yes. The tool works in mobile browsers on Android and iPhone, so you can stamp a document with text or a logo directly from your phone. This is handy for quickly marking a file Draft or Confidential before sharing it in a chat or email.
