Frequently Asked Questions
Can you add a watermark to a PDF without Adobe Acrobat?
Yes! Convert-To.co lets you add watermarks to PDF files free online without Adobe Acrobat or any software installation. Simply upload your PDF, customize the watermark text and appearance, and download your watermarked document instantly.
How do I add a watermark to PDF on Mac for free?
Use Convert-To.co directly in Safari or any Mac browser. Upload your PDF, set your watermark text (like "CONFIDENTIAL" or "DRAFT"), customize font, color, and position, then download your watermarked PDF. Works perfectly on macOS without Preview or Adobe.
Can I customize the watermark position and transparency?
Absolutely! You can control vertical position (top/center/bottom), horizontal position (left/center/right), rotation angle, opacity percentage for transparency, margins, and whether the watermark appears above or below page content. Full customization available.
How do I add a "CONFIDENTIAL" or "DRAFT" watermark to PDF?
In the watermark text field, type "CONFIDENTIAL", "DRAFT", "SAMPLE", or any custom text you need. You can then adjust the font size (default 40pt), opacity (default 60%), and rotation angle (default -45°) to get the professional diagonal watermark look.
Can I add watermarks to specific pages only?
Yes! Use the "Page Range" option to specify which pages should get the watermark. Enter page numbers like "1-5" for pages 1 through 5, or "1,3,5" for specific individual pages. Leave blank to watermark all pages.
What fonts are available for PDF watermarks?
Choose from 30+ professional fonts including Arial, Helvetica, Times New Roman, Courier New, Georgia, Verdana, Trebuchet MS, and Impact. Each font has regular, bold, italic, and bold italic variants. Default is Helvetica Bold for maximum readability.
Is the watermark permanent or removable?
The watermark is permanently embedded into the PDF file content. Once applied, it cannot be easily removed without PDF editing software. This ensures your "CONFIDENTIAL" or copyright watermarks stay protected. Your original file remains unchanged - download a copy with watermarks.
Where are my PDF files stored after adding watermarks?
Your files are never permanently stored. They're processed securely and automatically deleted after 15 minutes. Convert-To.co prioritizes privacy - we never access, share, or retain your documents beyond the watermarking process.
