Add Watermark to PDF Locally — Logo Stamping
Stamp your logo or a text watermark onto PDF pages without uploading the document.
Adding a watermark to a PDF — for version control, confidentiality marking, or branding — normally means uploading the document to a cloud service. FixIt Localy applies watermarks entirely in your browser. Upload your logo or type a text watermark, adjust its opacity and position, and download the watermarked PDF.
