A PDF watermark tool lets you stamp text or image watermarks on every page of a PDF directly in your browser — no Adobe Acrobat, no software installation, and no account needed. Customize the watermark text, font, color, opacity, rotation, and position, then download the stamped PDF instantly.
At PDFFixNow, you can add a watermark to a PDF online for free. Works on Windows, Mac, iPhone, and Android.
Types of watermarks you can add: Our tool supports two types: Text watermarks — any custom text such as CONFIDENTIAL, DRAFT, SAMPLE, or your company name — and Image watermarks — your logo or any JPG/PNG image placed at a custom size, position, and opacity. Both types are permanently embedded into the PDF page content.
Why watermark a PDF? Watermarks serve two main purposes: protection — marking a document as confidential, a draft, or for review only — and branding — adding your company logo or name to every page of a report, proposal, or ebook before sharing it externally.
Drag and drop your PDF into the upload box or click to browse your device. You can upload a single file or up to 10 PDFs for batch watermarking.
Choose Text or Image watermark. For text: enter your text and set font, size, color, opacity, and rotation angle. For image: upload your logo and set position and opacity. The watermark will be applied to every page of the PDF.
Click "Apply Watermark" to stamp your PDF. Download the watermarked file immediately. For batch uploads, all files are packaged into a ZIP archive.
PDF watermarks are used in many professional workflows to protect, brand, and manage documents. Here are the most common situations where adding a watermark is the right choice.
Custom Text Watermarks
Create text watermarks with any wording — CONFIDENTIAL, DRAFT, SAMPLE, your company name, or any custom text. Choose font, size, color, opacity, and rotation angle. Set the watermark diagonal, horizontal, or at any custom angle.
Flexible Positioning & Opacity
Place your watermark exactly where you want it: center, top-left, top-right, bottom-left, bottom-right, or a custom position. Control opacity from fully transparent to fully opaque to keep the watermark visible without obscuring your content.
Image Watermarks
Upload your company logo or any image (JPG or PNG) and use it as a watermark. Set the size, position, and transparency to integrate it seamlessly into every page of your PDF without overlapping important content.
Permanent & Tamper-Proof
Watermarks added by our tool are permanently embedded into the PDF page content. They cannot be easily removed by recipients without specialist software — unlike simple overlay watermarks that can be stripped with a text editor.
Batch Watermark Multiple PDFs
Apply the same watermark to up to 10 PDF files at once. Upload all files, configure your watermark settings once, and process the entire batch in a single operation — saving time when stamping multiple reports or documents.
Secure & Private Processing
Your documents are processed with TLS encryption and automatically deleted from our servers after 2 hours. We never read, store permanently, or share your files.
