Frequently Asked Questions
Everything you need to know about Add Watermark
What is a PDF watermark?
A PDF watermark is text or an image that appears on every page of a PDF document. It's commonly used to mark documents as confidential, drafts, copyrighted material, or to add branding. Watermarks are typically semi-transparent so the underlying content remains visible.
Can I add both text and image watermarks?
Yes! Our tool supports both text watermarks (like 'CONFIDENTIAL' or 'DRAFT') and image watermarks (like logos or stamps). Simply switch between the text and image tabs to choose your preferred watermark type.
How do I control watermark transparency?
Use the opacity slider to adjust watermark transparency. Lower values (0.1-0.3) create subtle watermarks that don't obscure the content, while higher values (0.5-1.0) make the watermark more prominent. The default 0.3 works well for most documents.
Can I position the watermark anywhere on the page?
Absolutely! Choose from 6 position options: Center, Top Left, Top Right, Bottom Left, Bottom Right, and Diagonal. The diagonal option automatically rotates the watermark at a 45-degree angle across the page for a classic watermark look.
Is my PDF safe when adding watermarks?
100% safe! All watermark processing happens locally in your browser. Your PDF never leaves your device, is not uploaded to any server, and is automatically deleted from memory when you close the page. Complete privacy guaranteed.
What image formats are supported for watermarks?
We support PNG and JPEG/JPG image formats for watermarks. PNG is recommended if your logo or image has transparent backgrounds. The tool will automatically handle the image embedding into your PDF.
Can I change the watermark color and size?
Yes! For text watermarks, you can customize the font size (12-96 points) and color using the color picker. You can also adjust the rotation angle (0-360 degrees) to create angled watermarks for added security.
Will the watermark appear on all pages?
Yes, the watermark is automatically applied to every page of your PDF document. This ensures consistent branding or marking throughout the entire document.
