05What is Add Watermark to PDF?
The ToolWala AI Add Watermark to PDF tool is a professional utility that applies custom text or image stamps onto PDF document pages. Standard watermarking services require you to upload your contracts, portfolios, or draft papers to remote servers, risking leaking private documents. Our tool runs entirely in your web browser. You can load a PDF, enter a custom text watermark or select a logo/image, adjust size, transparency, rotation angle, and position alignment, preview the output instantly on the page layout, and compile the final document locally. Your original files and metadata are preserved securely.
