Frequently Asked Questions
What is a PDF watermark?
A PDF watermark is a semi-transparent text or image overlaid on each page of a PDF document. It's commonly used to indicate document status (e.g., "CONFIDENTIAL", "DRAFT"), protect intellectual property, or add branding. Watermarks can be positioned anywhere on the page and rotated to your preferred angle.
How do I add a text watermark to my PDF?
Simply upload your PDF, select "Text Watermark", enter your desired text (or choose a preset like CONFIDENTIAL or DRAFT), customize the font, size, color, opacity, rotation angle, and position — then click "Add Watermark & Download". The tool processes everything directly in your browser.
Can I use an image as a watermark?
Yes! Switch to "Image Watermark" mode and upload a PNG or JPG image. PNG images with transparent backgrounds work best for professional-looking watermarks. You can adjust the scale, opacity, rotation, and position of the image watermark.
What is tiled watermarking?
Tiled watermarking repeats the watermark across the entire page in a grid pattern. This provides maximum document protection since the watermark appears multiple times, making it much harder to remove or obscure. You can customize the number of columns and rows for the tile grid.
Is my PDF safe? Where does the processing happen?
Absolutely. All processing happens entirely in your browser using client-side technology. Your PDF files are never uploaded to any server. We cannot access, view, or store your documents. This ensures complete privacy and security for sensitive documents.
Can I add watermarks to specific pages only?
Yes! You can choose to apply the watermark to all pages, only the first page, or specify a custom page range. Custom ranges support formats like "1-5" (pages 1 through 5), "1,3,5" (specific pages), or combinations like "1-5,7,9-12".
What file formats are supported for image watermarks?
We support PNG and JPG/JPEG formats for image watermarks. PNG is recommended because it supports transparent backgrounds, which creates a cleaner, more professional watermark appearance.
Is there a file size limit?
The recommended maximum file size is 50 MB. Since processing happens in your browser, very large files may take longer to process and could impact performance on devices with limited memory. For optimal performance, we recommend files under 30 MB.
