Frequently Asked Questions
How do I stamp DRAFT everywhere?
Enter text with diagonal placement at 25–30% opacity: readable but unobtrusive across all pages. One setting covers the whole file.
Removable by recipients?
Text watermarks flatten optionally — flattened marks resist casual removal; unflattened ones edit off. Flatten before adversarial sharing.
Position and size?
Diagonal center for documents, footer corners for branding. Size to page: 48pt suits A4, larger for posters.
Are my PDFs uploaded?
No — stamping runs locally in your browser. Saves never touch a meter — downloads on local tools are unlimited.
