Common Questions
Can I watermark a multi-page PDF?
Yes. The watermark is applied to every page automatically, no matter how many pages your document has.
Is the watermark permanent?
Yes. The text is drawn into the PDF page content, so it appears on every viewer and print — it is not a removable annotation.
Is it free and private?
Yes. The PDF is processed in your browser and never uploaded. It is completely free with no signup required.
