Frequently asked questions
How is the watermark centered horizontally?
Using a rough estimate — it subtracts (text length × 12px) from half the page width, rather than measuring the actual rendered width of your text, so longer text or unusual characters can throw the centering off a bit.
Can I change the watermark's angle, color, or font size?
No — only the text and opacity (5%-80% via the slider) are adjustable; the diagonal 45° angle, gray color, and 60pt size are fixed.
Is the watermark applied to every page?
Yes — the same text, size, angle, and opacity are stamped once on every page of the PDF.
