Why ForgePDF Add Watermark is Completely Private
🔒 The watermark is drawn locally with pdf-lib in your browser. Neither your document nor your watermark text is uploaded, which matters when marking confidential files.
Frequently Asked Questions
Can I change the color or position?
The watermark is a red diagonal text stamp. You can change the wording and opacity but not the color or angle.
Can a watermark be removed later?
It is drawn onto the page, so it is not a switch you can turn off. Keep your original unmarked file.
