PDFs are one of the most commonly shared document formats in business and creative industries. Without a watermark, they can be forwarded, downloaded, and redistributed without any trace of the original owner. Watermark.ws lets you upload any PDF, add a text or logo watermark to every page, and download the stamped document — all directly in your browser with no software to install.
Your watermark is applied consistently across every page of the PDF document. Whether your file is 2 pages or 200, every page gets the same professional watermark treatment in a single operation.
Mark proposals as "Confidential," stamp portfolios with your brand, or add "Draft" labels to working documents. PDF watermarking is essential for protecting sensitive business materials before sharing.
Set the opacity low for a subtle background watermark that does not interfere with reading, or make it bold and prominent for maximum visibility. Full control over size, color, position, and transparency.
Get started in minutes — no download required.

Drag and drop your PDF file into Watermark.ws or select it from your device. The tool processes multi-page PDFs and handles documents of any length.
Add Your Watermark
Type your watermark text — "Confidential," "Draft," your company name, or a copyright notice. Or upload your logo. Customize the size, color, opacity, rotation, and position on the page.
Download Your Stamped PDF
The watermark is applied to every page of the document. Download the finished PDF and share it with clients, colleagues, or the public — your ownership mark travels with the file.
Yes. Watermark.ws applies your watermark to every page of the PDF document automatically. You do not need to process each page individually — upload the full document and the watermark appears on all pages.
Any standard PDF file can be watermarked, including proposals, contracts, ebooks, portfolios, reports, and marketing materials. If you can open the PDF, Watermark.ws can watermark it.
You control the opacity and position. Many users set the watermark at low opacity (15-30%) and place it diagonally across the page, so it is visible as a background mark but does not interfere with reading the document content.
Yes. You can layer multiple watermarks on the same document. For example, add your company logo in the corner and a "Confidential" text stamp across the center of each page.
Add your watermark to any PDF document in seconds. Protect proposals, portfolios, and confidential files — no PDF editor needed.
