Frequently Asked Questions
Can I use text or an image as a watermark?
Both. Add a line of text (like DRAFT or CONFIDENTIAL) or upload a PNG or JPG logo to stamp across your pages.
Can I make the watermark faint so text stays readable?
Yes. An opacity slider lets you make the watermark as subtle or bold as you like, and you can rotate it diagonally.
Does the watermark go on every page?
Yes. The watermark is applied to every page of the PDF in one step (or just the first page if you prefer).
Is my PDF uploaded to a server?
No. The watermark is applied inside your browser using JavaScript. Your file never leaves your device.
