What does Insert Watermark do?

It places a semi-transparent text, image, or repeating pattern overlay on your PDF pages. You control the content, position, opacity, rotation, and which pages receive the watermark.

Is my PDF uploaded to a server?

No. Watermarking runs in your browser. Your file and your watermark image stay on your device.

Can I use my company logo as a watermark?

Yes. Choose the image watermark type and upload your logo. You can adjust size, opacity, rotation, and position.

What is a pattern watermark?

It tiles your text across the entire page in a repeating grid. Useful for marking every part of a page as CONFIDENTIAL or DRAFT, making it hard to crop out.

Can I apply different watermarks to different pages?

Yes. Switch to per-page mode and configure individual overrides for any page. The rest use the global settings.

Can I save watermark settings for reuse?

Save any configuration as a named preset. Presets include the watermark type, text/image, position, opacity, and rotation.

Does it work with password-protected PDFs?

Yes. You’ll be asked for the password. Decryption happens locally in your browser.

Can I watermark PDFs on my phone?

Yes. The mobile layout puts watermark settings in a bottom sheet with a floating apply button.

About Insert Watermark

How PDF Watermarking Works

A watermark is a semi-transparent overlay placed on your PDF pages. It can be text (“CONFIDENTIAL”, “DRAFT”), an image (a company logo), or a repeating pattern that tiles across the entire page.

OxygenPDF applies watermarks directly in your browser. Pick a type, adjust the settings, preview the result on your actual pages, then apply. The watermarked PDF downloads to your device. Nothing gets uploaded.

Common Reasons to Watermark PDFs

Watermarks serve a practical purpose. They mark document status, establish ownership, or discourage unauthorized distribution.

Protect Intellectual Property

Overlay your company logo or copyright notice on reports, proposals, and creative work before sharing externally.

Mark Document Status

DRAFT, CONFIDENTIAL, FOR REVIEW, APPROVED — text watermarks make a document’s status immediately visible on every page.

Legal & Compliance

Court filings and regulated documents often require visible markings. Watermarks satisfy the requirement without obscuring content.

Brand Documents

Place a logo watermark on client-facing materials. Adjust opacity so it’s visible without competing with the actual content.

Three Watermark Types: Text, Image, and Pattern

Text watermarks let you type any message and control font, size, color, opacity, and rotation. Image watermarks accept a logo or graphic — upload it, set the size and transparency, and position it on the page. Pattern watermarks tile your text across every page in a repeating grid with configurable spacing.

Each type supports nine position presets (center, corners, edges, diagonal) plus custom placement. You can save watermark configurations as presets for reuse, and apply different watermarks to different pages using per-page overrides.

How It Compares

Most PDF tools offer basic text watermarks. The range of options and the live preview vary significantly.

Your Documents Stay Private

Documents that need watermarking are usually the ones you’d rather not upload anywhere: contracts before signing, financial reports under review, internal presentations with proprietary data.

OxygenPDF renders watermarks locally in your browser. Your PDF stays on your machine. The watermarked output downloads directly. Close the tab and nothing remains.
