Watermark PDF FAQ
Can I put a CONFIDENTIAL watermark on a PDF?
Yes. Enter CONFIDENTIAL as the watermark text, set a slight angle and moderate opacity, and every page is stamped automatically in your browser.
Can I adjust the watermark transparency?
Yes. PDFForge lets you control opacity so the watermark can be subtle or prominent while keeping the underlying content readable.
