Frequently Asked Questions
Can I control how visible the watermark is?
Yes. Use the Opacity slider to set the watermark from nearly invisible (5%) to fully solid (100%). A faint watermark around 20–40% is typical for professional documents.
What positions are available for the watermark?
You can place the watermark diagonally across the center of each page (the most common style), at the top center, or at the bottom center.
Is the watermark added to every page?
Yes. The watermark text is applied to every page in the PDF document with consistent styling.
Can I choose any color for the watermark?
Yes. Use the color picker to select any color, or click one of the preset swatches for common options like red, blue, green, gray, or black.
Will the watermark affect the original PDF content?
The watermark is drawn on top of each page's existing content. The underlying text and images remain intact. The downloaded file is a new PDF — your original file is unchanged.
