Is the PDFVibe watermark tool really free?

Yes, PDFVibe Watermark PDF is completely free to use with no hidden costs, no watermarks added by the tool itself, no file size limits, and no registration required. You can watermark unlimited PDF documents at no charge.

Are my documents safe when adding watermarks with PDFVibe?

Absolutely. PDFVibe processes your PDF files 100% locally in your browser using WebAssembly technology. Your documents are never uploaded to any server — they remain entirely in your device's RAM throughout the process. This makes it the safest watermarking tool available for confidential documents.

Can I add both text and image watermarks?

Yes. You can choose between text mode (where you type custom text like DRAFT, CONFIDENTIAL, or your company name) and image mode (where you upload a logo, stamp, or any image file). Image watermarks support PNG files with transparent backgrounds for professional overlay effects.

How do I control watermark transparency?

Use the opacity slider to set transparency from 0% (fully transparent) to 100% (fully opaque). Most users find 20-40% opacity ideal for watermarks that are visible but don't obstruct the underlying document content.

Can I preview the watermark before applying it?

Yes, PDFVibe provides a live preview canvas that shows exactly how your watermark will appear on the document page. You can adjust all settings — text, size, angle, opacity, position — and see the changes reflected in real-time before committing.

Does the watermark apply to all pages?

Yes, by default the watermark is applied uniformly to every page in your PDF document. This ensures consistent branding or protection across the entire file, which is essential for legal documents, reports, and multi-page contracts.
