Consistent watermarking creates powerful recognition and builds professional credibility over time across all pages.

Frequently Asked Questions
Can I watermark PDF files on my phone?
Absolutely! Our watermark tool works perfectly on mobile devices including iOS and Android without downloading any app. Just open your browser, upload your PDF file, customize your watermark, and download the finished result.
Whether you're using iPhone, Android, or tablet, the interface adapts flawlessly to your screen size. You get the same professional watermarking power right in your pocket, with no installation needed on any device.
What watermark options do I have?
You get complete creative control over every watermark element. Choose from text watermarks, image logos, or both combined for maximum branding impact. Our tool supports all popular image formats and gives you full control to create exactly what you need.
- Text Options: Any font, size, color, or rotation angle you want for perfect positioning and style matching across all pages.
- Image Support: Upload PNG, JPEG, or SVG logos with transparent backgrounds for professional branding that doesn't look cheap. Resize and position as needed.
- Positioning Control: Place watermarks anywhere on the page with precise pixel-level accuracy and opacity settings to add watermark to your PDF perfectly.
- Batch Consistency: Apply identical watermarks across multiple PDFs automatically, saving hours of repetitive manual work when you need to add watermarks to many files.
The flexibility means your watermarks always match your brand guidelines exactly, whether you need subtle background text or bold corner logos. Note that you can select specific pages for watermarking if desired.
Is my document information kept private?
Yes, we take document security seriously with enterprise-grade protection throughout the entire watermarking process. Your files are encrypted the moment they hit our servers with default security settings that protect confidential information.
All uploaded PDF documents get automatically deleted within 2 hours after processing, so your sensitive information never lingers on our systems. We don't store, share, or analyze your document contents on any of our servers.
How does batch watermarking work?
Upload multiple PDF files at once and apply identical watermarks to all of them simultaneously. Perfect for agencies, businesses, or anyone processing large document collections efficiently without needing to install special software.
Simply drag and drop all your PDF documents into the upload area, customize your watermark settings once, and hit process. Every file gets watermarked with identical positioning, opacity, and branding elements automatically. You can choose to watermark PDF pages selectively or apply to all pages by default.
Can I remove watermarks I don't like?
Once you download your watermarked PDF, the watermark becomes part of the document permanently. However, you can always re-upload the original file and try different watermark settings to create a new version.
That's why we recommend previewing your watermark placement and opacity before final processing. The preview shows exactly how your finished PDF pages will look, so you can adjust transparency, resize elements, or edit positioning as needed.
What file formats work for watermark images?
We support PNG, JPEG, and SVG image formats for logo watermarks. PNG files work best because they support transparent backgrounds for professional-looking results that don't appear opaque where you don't want them.
SVG files scale perfectly at any size without pixelation, making them ideal for logos that need to look crisp at different document sizes. You can resize any image format and adjust transparency to get the perfect look across all pages of your PDF documents.
Are there any file size limits?
Our watermark tool handles PDF files up to 100MB per file, which covers virtually every document type you'll encounter on Windows, Mac, or Linux systems. For batch processing, you can upload up to 20 files simultaneously.
Larger files require slightly more processing time but maintain the same professional quality results. The tool automatically optimizes processing speed based on your document size and complexity, ensuring you can add watermark to PDF documents efficiently regardless of size.
What makes this better than other watermark tools?
Most free watermarking tools add their own ugly branding to your documents or limit how many files you can process daily. This tool gives you clean results every time you add watermark to PDF documents.
- Zero Added Branding: Your watermarked PDF documents stay completely clean without our logo stamped anywhere on your professional files.
- Unlimited Processing: Add watermarks to as many files as you need without daily caps, subscription requirements, or hidden upgrade prompts.
- Professional Quality: Advanced processing ensures your watermarks look crisp and professional, not pixelated or cheap like basic tools produce when you watermark PDF documents.
- Complete Customization: Full control over positioning, opacity, rotation, and styling that most competitors don't offer in their free versions. Select font options, adjust transparency, resize elements, and set exact placement.
You get enterprise-level watermarking capabilities without paying enterprise prices or dealing with the usual restrictions that make other tools frustrating to use.
