Watermark PDF
Stamp text such as CONFIDENTIAL on every page
Frequently asked questions
Can the watermark be removed later?
The watermark is drawn into the content of each page, so it can't be switched off like a layer in an ordinary PDF reader. Someone with PDF editing software can still edit or cover it, so a watermark discourages reuse but isn't a security measure. Keep a copy without the watermark if you'll need a clean version.
Can I write the watermark in any language?
Yes. Text in the Latin alphabet is added as real text. Other scripts, such as Chinese or Arabic, are drawn as a high-resolution transparent image, so they display correctly without embedding a large font in your file.
Does the watermark change the rest of the document?
No. The original pages are kept as they are, with selectable text, links and images. The watermark is only added on top of each page.
Is my file uploaded to add the watermark?
No. The watermark is drawn in your browser with pdf-lib, and the file never leaves your device.
How it works
From file to finished PDF in three steps
2
Processed on your device
Your browser does the actual work using WebAssembly and JavaScript (pdf-lib, pdf.js), the same technology behind offline apps. The file itself never leaves your computer.
3
Download the result
As soon as processing finishes, your browser triggers a normal file download. Nothing is stored on our end — there's no server copy to delete because one was never made.
Real Privacy: Your Files Never Leave Your Device
Unlike traditional online PDF tools, The PDFverse works entirely client-side using WebAssembly and JavaScript. Your documents are never uploaded, stored, or accessed by third-party servers.
Zero Uploads
Not a single byte of your document is sent to any server.
Zero Latency
Instant processing without waiting in cloud queues.
100% Confidential
Ideal for legal contracts, financial sheets and private records.
