Frequently Asked Questions
Can I watermark every page at once?
Yes. Your watermark is applied across all pages of the PDF in a single step.
Can I control the text, position, and transparency?
Yes. You set your own watermark text and adjust how it appears so it stays visible without hiding the content underneath.
Is my PDF uploaded to a server?
No. The watermark is added in your browser, so your document never leaves your device, which is safe for confidential files.
