Frequently Asked Questions
Can I use text, a logo, or both? ▼
Both. Stamp words like
CONFIDENTIAL or DRAFT, add your own logo or image, or combine the two on the same page.What can I customise? ▼
For text you can set the words, colour, size and opacity. You choose how bold or faint the mark looks and where it sits, so it never overwhelms the page.
Does the watermark go on every page? ▼
Yes. The watermark is applied across all pages of the PDF, so the whole document is marked consistently.
Will a watermark make my content unreadable? ▼
Not if you use a lower opacity. A faint, semi-transparent mark sits over the page while keeping the text and images underneath easy to read.
Can a watermark be removed later? ▼
Once applied it becomes part of the page, so it isn't meant to be peeled off. Keep your original file if you'll need a clean, unmarked copy.
Is my PDF uploaded anywhere? ▼
No. Everything runs entirely in your browser on your own device. Your file is never uploaded and we never see it.
