COMMON QUESTIONS

Frequently Asked Questions

Everything you need to know about PDF watermarking
? Can I add both text and image watermarks to my PDF?
Yes! You can choose to add custom text (such as "CONFIDENTIAL" or "DRAFT") or upload image watermarks (like logo files), and customize their scaling, angle, and opacity.
? Does the watermarking process compromise document quality?
Not at all. The tool processes vectors and images with high precision, maintaining your original PDF text, layout quality, and formatting perfectly.
? Are my private PDF documents secure during watermarking?
Yes, entirely secure. Because all processing runs locally on your machine using advanced client-side Javascript, your PDF is never uploaded to any remote servers.
? Can I control where on the page the watermark is printed?
Yes, you can align the watermark in different default layout grids (e.g., top-left, center, bottom-right) or specify custom coordinates and tilt/rotation angles.
? Is there a page limit or size restriction for watermarking?
No. Since processing happens client-side, the file size and page limit depend entirely on your computer's RAM and CPU capabilities.
? Does it add any promotional watermarks of its own?
No. This tool is completely free and clean. We do not insert any advertisement, brand logo, or promotional watermarks into your final output.
