Frequently Asked Questions
Quick answers about privacy, customization options, and how the PDF watermark tool works.
Is this PDF watermark tool free to use?
Yes. This PDF watermark tool is completely free and does not require registration or account creation.
Is my PDF uploaded to a server?
No. All PDF processing happens locally in your browser. Your files never leave your device.
Can I add watermarks to specific pages only?
Currently, watermarks are applied to all pages in the document. For selective page watermarking, you can first extract the pages you need, then apply the watermark.
Can I use image watermarks?
This tool supports text watermarks only. For image watermarks, you would need a more advanced PDF editor.
Does this tool support encrypted PDFs?
Password-protected PDFs may not work without first entering the correct password. Standard PDFs without encryption are fully supported.
Can I customize the watermark appearance?
Yes. You can customize the text, opacity (5%-80%), font size (20px-100px), and color of your watermark.
Is there a file size limit?
There is no fixed upload limit. Performance depends on your device and browser memory when processing very large PDF files.
Can I use this tool for commercial projects?
Yes. You may use this tool for personal or commercial purposes without restrictions.
