Frequently asked questions

Is Add Watermark free to use?

Yes. Add Watermark is completely free — no signup, no watermarks, and no file limits. It runs locally in your browser, so there is no server cost to pass on.

Is my file uploaded to a server?

No. Watermark placement and export happen fully on your device. Processing happens with JavaScript in your browser, so your document never leaves your device.

Does Add Watermark work offline?

Yes. Once the page has loaded, processing runs entirely on your device, so it keeps working without an internet connection.

Add Watermark accepts PDF files and produces a Watermarked PDF. Useful for drafts, internal reviews, confidential files, and branded handoffs.

Do I need to install any software?

No. Add Watermark works in any modern browser — Chrome, Firefox, Safari, or Edge — on Windows, macOS, Linux, iOS, and Android. There is nothing to download or install.
