Why Add Watermarks to PDFs?

Watermarking PDF documents is essential for legal and business use. Lawyers mark documents as DRAFT to prevent premature reliance, CONFIDENTIAL to restrict distribution, and PRIVILEGED to assert attorney-client protection. Businesses use watermarks like COPY and SAMPLE to control document versions. Our free tool makes this process instant and private.
