Sharing PDFs is a routine part of business, but an unmarked file can be copied, forwarded or claimed by someone else. Watermark.ws stamps your PDF with a text or logo watermark and gives it back as a PDF. Premium and Ultimate watermark every page; the free plan watermarks the first page so you can check the result.

How it works

  1. Step 1: Upload Your PDF

    Drag your PDF onto the page or browse to select it. A PDF that needs a password to open has to have the password removed first.

  2. Step 2: Design Your Watermark

    Add a text or logo watermark and set its font, color, size, opacity and position. The preview shows it on your document.

  3. Step 3: Download Your PDF

    Download the watermarked PDF and share it with clients, colleagues or partners. Your original file is not changed.

What you can do

Document Protection

Stamp your PDF with a text or logo watermark to discourage forwarding and reuse. Made for confidential contracts, draft proposals, internal reports and client deliverables.

Watermark Every Page

On Premium and Ultimate the watermark goes on every page of the PDF in one go. The free plan watermarks the first page.

Custom Text and Logo Watermarks

Add CONFIDENTIAL, DRAFT, your company logo or any text. Set the font, color, size, opacity, angle and position so the watermark sits well on the page.

Questions people ask

Can I watermark every page of a multi-page PDF?
Yes, on Premium and Ultimate: the watermark is applied to every page automatically. The free Basic plan watermarks the first page.
What kind of watermarks can I add to a PDF?
Text watermarks such as CONFIDENTIAL or DRAFT, your company logo, a signature, or any custom text. Set the font, color, size, opacity and placement, or tile the watermark across the page.
Will the watermark affect the readability of my PDF?
You control the opacity and position. Lower the opacity for a background mark that leaves the text easy to read, or raise it for a more prominent stamp.
Do I need to install any software to watermark PDFs?
No. Watermark.ws works in any modern browser: upload your PDF, add your watermark and download the result. Word documents (.docx) are supported the same way and stay .docx.
