Upload your PDF from your computer or Dropbox, or simply drag and drop it into the upload area. Your document will be ready for watermarking in just a few seconds.
Enter the text you want to use as a watermark or upload an image, such as your company logo or custom design, to appear across your PDF pages.
Adjust the watermark's position, rotation, size, opacity, and alignment. Use the live preview to ensure it appears exactly as you want before processing.
Click Convert to apply the watermark. Your new watermarked PDF will be processed and ready to download within moments.
Create custom text watermarks using your name, company, date, serial number, or any text you choose. Customize the font, size, color, style, and effects to match the look and feel of your document.
Rotate your watermark anywhere from 0° to 360° and place it exactly where you want, including the center, corners, or custom positions. This gives you complete control over its appearance without covering important content.
Adjust watermark transparency from 0% to 100% for a subtle or bold effect. Apply the watermark to every page or only selected pages within your PDF.
Upload your logo, signature, or any image to use as a watermark. Resize, rotate, and adjust its transparency to create a professional branded document.
Apply the same watermark to multiple PDF files in a single operation. Batch processing saves time when branding reports, invoices, contracts, or large collections of documents.
Preview your watermark before applying it to the final PDF. Zoom in to verify its size, placement, rotation, and transparency, ensuring the result looks exactly as intended.
Your PDFs are protected with strong encryption throughout the upload and watermarking process. After processing is complete, files are automatically deleted from our servers to keep your documents private and secure.
Watermarks are added without affecting your PDF's original layout, text, images, or formatting. The finished document maintains its professional appearance while clearly displaying your watermark.
Add text or image watermarks with complete control over placement, rotation, transparency, size, and page range. Create anything from subtle branding to bold document labels with ease.
Add watermarks directly from any web browser on your phone, tablet, or computer. Fast cloud processing ensures your PDFs are ready to download within seconds.
Whether you're watermarking a single-page document or a large batch of PDFs, our tool delivers reliable performance and consistent results without compromising quality.
Add text watermarks such as "Internal Use Only" or "Confidential" to business plans, financial reports, and company strategies before sharing them with employees or stakeholders. This helps discourage unauthorized distribution while keeping the content readable.
Protect portfolios, design mockups, photography collections, and artwork by adding your logo or copyright watermark. Place it discreetly in a corner or across the page to establish ownership without hiding the design.
Add watermarks such as "Draft", "Reviewed", or "Confidential" to contracts, agreements, and legal documents. Lower transparency keeps the text easy to read while clearly indicating the document's status.
Teachers, schools, and training organizations can add institution names or logos to lesson notes, worksheets, and study guides to reinforce ownership when sharing educational materials online.
Add event dates, version numbers, or organizer branding to promotional flyers and event brochures. Watermarks make it easy to identify the latest version while maintaining a professional appearance.
Text and image watermarks serve different purposes. Choosing the right option depends on what you want your watermark to communicate.
Text Watermarks are ideal for status labels, ownership notices, dates, or serial numbers. Messages such as "Confidential", "Draft", or "For Internal Use Only" are best displayed as text because they remain lightweight and easy to customize.
Image Watermarks are the preferred choice for branding. Upload your company logo, signature, or custom graphic to give documents a professional appearance while reinforcing your visual identity.
Combine Both for Better Results by adding an image watermark for branding and a text watermark for document status. For example, place your company logo in the corner while applying a diagonal "Draft" watermark across the page.
Adjust Transparency Carefully to control how noticeable your watermark appears. Lower opacity creates a subtle ownership mark, while higher opacity makes status labels more visible without hiding important content.
Watermark PDF (this tool) adds text or image overlays for branding, copyright protection, ownership, or document status. It helps identify documents without changing their content.
Add Page Number inserts sequential page numbers for navigation and document organization. Choose this tool when your goal is to improve readability rather than brand or label the document.
Sign PDF adds an electronic or digital signature to verify approval and authenticity. It is intended for legally approving documents rather than branding or marking them.
Protect PDF secures your document with password protection. Unlike a watermark, password protection prevents unauthorized users from opening the file, while a watermark simply labels or brands the document.
● Lower transparency works better for watermarks placed over dense text, so the underlying content stays readable rather than competing visually with the stamp.
● For status labels like "Draft" or "Confidential," diagonal placement across the center of the page is typically more visible and harder to crop out than a small corner stamp.
● If pages need reordering before a full document is watermarked, Organize PDF can handle that first, so the watermark ends up applied to pages already in their final sequence.
● Watermarked reports from multiple sources can be brought together with Merge PDF once each has been stamped individually.
● If a batch of watermarked files grows too large to share easily, Compress PDF afterward reduces file size without affecting the watermark already applied.
