Marking a document as "Draft" or "Confidential", or protecting a file with your brand name? This guide shows you how to add a watermark to a PDF for free, right in your browser — no software, no upload, no sign-up.
Go to MyPDFEasy Watermark PDF — works in any browser, no installation required.
Click "Choose PDF" or drag and drop your file.
Enter text like "Draft", "Confidential", or your company name.
Use the live preview to fine-tune how the watermark looks before applying it.
Click "Add Watermark & Download" to stamp every page and save your new PDF.
💡 Pro Tip: Keep the opacity low (around 15-25%) if you still want the watermarked document to be easy to read — a bolder watermark is better for drafts you don't mind looking heavily marked.
MyPDFEasy adds the watermark entirely inside your browser using pdf-lib. This means:
Upload your PDF, type your watermark text, adjust size, color, opacity, and angle, then click "Add Watermark & Download". It is completely free.
