Professional PDF Protection and Branding

Whether you are labeling a draft, marking a document as "Confidential," or adding your brand name, our tool ensures the watermark is applied consistently across every page.

Encrypted Local Processing

Sensitive documents require the highest level of security. Our watermark engine runs 100% in your local browser environment. Your files are never uploaded, processed, or stored on our servers, ensuring your data remains in your hands at all times.
