How It Works

Simple steps to get your converted file

1

Upload your PDF

Drop your PDF. All pages are ready to be stamped — you can target all of them or just specific ones.

2

Configure the watermark

Type your text (or upload an image logo), set opacity, font size, color, position, and rotation. A live preview shows the result instantly.

3

Download the stamped PDF

Click Download and get the watermarked PDF. The stamp is flattened into the content — it cannot be trivially removed.

Design Your Watermark

Type your text or upload a logo, set opacity and rotation, choose which pages to stamp — see a live preview before downloading.

Full Watermark Control

Text or image, any opacity, any position — with a live preview so what you see is exactly what you get.

Text or Image Watermark

Add a custom text stamp — 'CONFIDENTIAL', 'DRAFT', your company name — or upload a logo image as a transparent overlay.

9-Point Positioning

Place the watermark at any of 9 grid positions — corners, edges, or center — or choose Diagonal to tile it across every page at 45°.

Opacity & Transparency

Set the watermark from fully opaque down to barely visible. Most professional watermarks sit at 20–40% so the page content stays readable.

Font, Size & Color

Choose from standard fonts, set any font size from 12pt to 144pt, and pick any color. Common choices: gray, red, or your brand color.

Apply Selectively

Stamp all pages, only the first page (cover), or a custom range. Useful for marking a cover page 'CONFIDENTIAL' while leaving body pages clean.

Live PDF Preview

See your watermark settings applied to the actual PDF page before you commit. Adjust and preview until it's exactly right.

Frequently Asked Questions

Everything you need to know about this tool

Yes — switch to Image mode, upload a PNG with a transparent background, and set the opacity. A PNG logo at 20–30% opacity sits cleanly over page content without obscuring it.

Yes — the watermark is flattened into the PDF as a content layer, not a separate annotation. It cannot be removed by simply deleting comments or form fields.

Once flattened, a content watermark cannot be automatically removed. To preserve the ability to remove it later, use our Annotate PDF tool which keeps the watermark as a removable annotation layer instead.

25–35% is the professional standard — visible enough to communicate the label clearly, light enough that the document content remains fully readable underneath.

Yes — in the 'Apply to' section, select 'First page only'. This is common for cover pages. You can also enter a custom page range like '1, 3-5' to watermark specific pages.
