How to Add Watermark to PDF for Free?
Protect your intellectual property and brand your documents by adding text or image watermarks. Watermarks prevent unauthorized distribution of drafts, design proofs, invoices, and certificates. WeLovePDF allows you to configure, position, and preview watermarks in real-time inside your browser memory with zero uploads.
Steps to Watermark a PDF:
- Upload PDF: Select the file you wish to brand.
- Configure: Enter your text, customize colors, opacity, and choose a position.
- Apply: Click "Run Tool" to overlay the watermark pattern on all pages.
- Download: Save your brand-marked PDF document.
Watermark Styling Tips:
Use a diagonal rotation angle (like 45°) to prevent users from cropping or hiding the watermark. Adjust the opacity slider to 20-30% to keep the background text readable while maintaining clear copyright markings. You can choose to apply the watermark pattern to all pages, only selected page indexes, or odd/even pages.
