Why Use PDF Watermark Software?

PDFs are widely shared online, but without protection, they can be misused or altered. Adding a watermark (e.g., text, website URL, or company name) ensures your PDFs remain secure and credited to you. Use cases include:

• Legal Documents: Add “Confidential” to protect sensitive contracts.
• Marketing Materials: Embed your brand name to promote recognition.
• Personal Files: Prevent unauthorized use with custom text.
