Frequently Asked Questions
Will this process flatten the PDF text content or graphics?
No. The watermark layers are appended directly as subset layers. The rest of your document texts, annotations, and vector paths remain editable.
What color and opacity values are recommended?
A red color (#e11d48) with 15% to 25% opacity is standard to ensure high readability while preventing photocopying.
Is my uploaded document kept safe?
Absolutely. All rendering and vector injection updates compile locally in your own browser sandbox. None of your document data is sent online.
