Frequently Asked Questions
Everything you need to know about our PDF watermark tool
What file formats does this tool support?
Our tool specifically supports PDF files for watermarking. For watermark images, you can use JPEG, PNG, and other common image formats. The tool is optimized to work with PDFs of any size and complexity.
Is my PDF secure when using this tool?
Yes, absolutely! All PDF processing happens directly in your browser using client-side JavaScript. Your files never leave your device or get uploaded to any server. This ensures complete privacy and security for your documents.
How do I use the PDF watermark tool?
Simply upload your PDF file, choose between text or image watermark, customize the appearance (size, color, opacity, position, rotation), preview the result, and click “Add Watermark” to process. Then download your watermarked PDF instantly.
Can I control the watermark position and appearance?
Yes! You have full control over watermark positioning (9 different positions), opacity (10-100%), rotation (-45° to +45°), size, and color. For text watermarks, you can adjust font size and color. For image watermarks, you can control the size and all styling options.
Are there any file size limitations?
The tool can handle most standard PDF files. Very large files (over 50MB) may take longer to process depending on your device’s capabilities. For optimal performance, we recommend PDFs under 20MB, though larger files will still work.
Is this tool free to use?
Yes, this PDF watermark tool is completely free to use! There are no hidden costs, registration requirements, or usage limits. You can watermark as many PDFs as you need without any restrictions.
