Who Uses Watermark PDF
Teams stamping CONFIDENTIAL or DRAFT across a document before it circulates outside the company. Agencies marking a proof so a client cannot use the file until it is paid for. Anyone sharing a scanned ID or certificate who wants the purpose written across it, so a copy cannot be reused elsewhere. Firms adding a company name across tender and quotation PDFs before sending them out.

Frequently Asked Questions
How do I put a watermark into a PDF?
Three steps: (1) Drop your PDF into the upload area above, (2) choose text or image watermark and customize the look (position, opacity, rotation, font/color), (3) click download. The watermark applies to every page (or only the pages you select). Everything runs in your browser - the PDF never leaves your device.
Can you watermark a PDF for free?
Yes - this tool is 100% free with no signup, no daily limit, and up to 20 PDFs at a time. Add text or image watermarks to any PDF (up to 100 MB each), with full control over position, opacity, rotation, and color. The free version is the full version - there's no paid tier.
How to add watermark in PDF without Adobe Acrobat?
You don't need Acrobat or any installed software. This browser-based tool uses pdf-lib to add watermarks directly in your browser - with no install, no subscription, and no file upload to a server.
How do I insert a watermark on every page?
By default, the watermark is applied to all pages of the PDF. If you want it on only specific pages, pick First only, Last only, Skip first, or Custom (e.g. 1-5 or 1,3,5,7). Live preview shows the result before you download.
How to find watermark in PDF?
Open the PDF in any reader and look for faded text/logos overlaid on the content - usually a diagonal 'CONFIDENTIAL' or 'DRAFT' stamp at 15-30% opacity, or a logo in a corner. If the watermark is in the page content (not metadata), it's part of the visual layer. To check the metadata, look at File → Properties in your reader.
Can I add multiple watermarks to a PDF?
Yes - process the PDF once with the first watermark (e.g., text 'CONFIDENTIAL' diagonally), download the result, then upload it again and add the second watermark (e.g., a logo in the corner). Each pass adds a new watermark layer without affecting earlier ones.
What types of watermarks can I add?
You can add text watermarks (any text, font, color, and size) or image watermarks (upload a PNG or JPG logo, signature, or stamp). Text watermarks support dynamic tokens like {page} for page numbers and {date} for the current date.
Can I add a 'CONFIDENTIAL' or 'DRAFT' stamp to my PDF?
Yes, this is one of the most common use cases. Type 'CONFIDENTIAL', 'DRAFT', or 'SAMPLE' as your text, set it to a large font size with low opacity, rotate it diagonally, and center it on the page for the classic stamp effect.
Can I add my company logo as a watermark?
Yes. Upload your logo as a PNG (transparent background works best) or JPG. Position it in a corner or center, adjust opacity so it doesn't obstruct the content, and apply it to all pages.
Can I control which pages get the watermark?
Yes. You can apply watermarks to all pages, the first or last page, all but the first, or a custom range (e.g. pages 1-5). This is useful for documents that need different watermarks on different sections.
What does the opacity setting do?
Opacity controls how transparent the watermark appears. 100% is fully visible (solid), 20-30% is semi-transparent (the classic watermark look where text behind it remains readable). Most users set opacity between 15-40% for a professional appearance.
Can I rotate the watermark diagonally?
Yes. You can set any angle from -180° to 180°. The most popular choice is 45° diagonal, which is the standard look for 'CONFIDENTIAL' and 'DRAFT' stamps.
Will the watermark cover the text in my PDF?
Not if you set the opacity correctly. Using 15-30% opacity ensures the watermark is visible but the underlying text remains fully readable. You can also choose to place the watermark behind the content.
Is my PDF safe when using this tool?
Yes. Unlike most online watermark tools that upload your PDF to their servers, our tool processes everything 100% in your browser using the pdf-lib library. Your document never leaves your device - you can even use it offline after the page loads.
