Frequently asked questions
Does the watermark get added to every page?
Yes, the same watermark (text or logo), position and opacity is applied to every page of the PDF in one pass.
Can I tile a “CONFIDENTIAL” stamp diagonally across pages?
Yes, choose “Tiled (repeat)” as the position, text watermarks are automatically angled when tiled, similar to how many document watermarks look.
Is my PDF uploaded to a server?
No, watermarking happens entirely in your browser using pdf-lib. Your file never leaves your device.
