Add a Watermark to Your PDF

Stamp diagonal text across every page of a PDF — "CONFIDENTIAL," "DRAFT," your name, or any label you choose. Type your text, open the file, and Squire watermarks all pages at once, then hands you a ready-to-download PDF.

Everything runs inside your browser. Your file is never uploaded to a server — it stays on your device from start to finish. There are no daily limits, no account, and no monthly subscription: Squire is a one-time $5 for the whole tool suite, a private alternative to Smallpdf and iLovePDF.

Questions

Are my files uploaded when I add a watermark?

No. Squire watermarks your PDF entirely inside your browser using your own device. The file never leaves your computer and is never sent to a server, so even sensitive or confidential documents stay private.

What kind of watermark can I add?

You can stamp diagonal text across every page of the PDF — for example DRAFT, CONFIDENTIAL, a name, or any label you type. The same text is applied to all pages at once.

Is there a limit or a subscription?

No daily limits and no monthly subscription. Squire is a one-time $5 for the full PDF tool suite, with no account required — unlike Smallpdf or iLovePDF, which throttle free use and charge every month.
