Watermark PDF on Windows
PDF watermarking on Windows traditionally means Acrobat Pro — a subscription for a stamp. The browser applies the same document-wide mark free: text or logo, every page, any Windows machine. Free with fair daily limits.

The subscription-for-a-stamp problem
Businesses watermark constantly — DRAFT on circulating versions, client names on proposals, CONFIDENTIAL on records — and paying Acrobat rates for it never sat right. The browser route does the job at exactly its worth: free.
Works where work happens
Office PCs with locked-down installs run it fine — the watermarking is server-side; Edge or Chrome merely ferries the file. The marked copy lands in Downloads, the original stays clean.
