Is this tool really free?

Yes, all our PDF tools are completely free to use with no hidden costs, subscriptions, or per-file charges. We support the service through non-intrusive advertising, not by charging for basic document operations. You can use any tool as many times as you like, with no daily limits, file size restrictions, or account requirements whatsoever.

Absolutely. All PDF processing happens directly in your browser using local JavaScript and WebAssembly libraries. Your files are never uploaded to any server, never stored in the cloud, and never transmitted over the internet. The files remain entirely on your device from start to finish, giving you complete control over your sensitive and confidential documents.

Can I add an image watermark?

Yes, you can add text or image watermarks. For image watermarks, upload a PNG or JPEG file — PNG with transparency works best, as the transparent areas let the page content show through naturally. You can control the image watermark's size, position, opacity, and rotation to achieve exactly the appearance you need.

Will the watermark be on all pages?

You can choose to apply the watermark to all pages at once or select specific pages to watermark. This is useful when you want to mark only certain sections of a document, such as marking only the first page as "Draft" or applying a confidentiality watermark to a specific range of pages.

Can I control the watermark opacity?

Yes, opacity is fully adjustable from completely transparent (0%) to fully opaque (100%). For most professional uses, an opacity of 20-40% creates a visible watermark that does not obscure the underlying document content. Higher opacity values make the watermark more prominent, which may be appropriate for draft or confidential markings.

What fonts are available for text watermarks?

The text watermark tool offers a selection of common fonts including standard serif and sans-serif typefaces. You can also adjust the font size and color to match your branding or document style. The diagonal orientation option is the most commonly used layout for watermarks, as it covers the page area without blocking specific lines of text.

Is the watermark permanent?

The watermark is embedded directly into the PDF page content, making it part of the visual layer of the document. However, in the standard PDF format, a technically skilled user could potentially edit the PDF to remove the watermark layer. For documents requiring tamper-proof protection, consider using a combination of watermarking and password-based restrictions.

Watermark PDF

Add custom text watermarks to every page of your PDF with full control over the text, font size, color, opacity, rotation angle, and position on the page. Watermarks are commonly used to mark documents as drafts, confidential, or for a specific recipient, making unauthorized distribution immediately visible. You can set the opacity low enough that the underlying content remains readable while the watermark is clearly visible. The watermark is embedded directly into the PDF pages, so it cannot be removed by simply deleting an annotation layer.
