When to use it

Tips
20–35% opacity at a -30° to -45° angle is visible without hiding content; use Tiled for stronger protection. You can apply it to specific pages only, such as 1-3, 5.
Good to know
The watermark becomes part of each page once saved. Everything runs in your browser; your file is never uploaded.
FAQ
Can the watermark use accented characters?
Yes. The text is drawn as a transparent image, so every accent and script displays correctly.
Can I stamp only some pages?
Yes, enter a page range like 1-3, 5 or 2- (page 2 to the end) to stamp only those pages.
