Apa yang bisa dilakukan Add a watermark to a PDF
Any text, any language
Type CONFIDENTIAL, DRAFT, a name — including non-Latin scripts. The watermark sits semi-transparent and angled across the page. Want it straight instead? Switch to horizontal in nopa's full PDF app.
Why your alphabet works here
The fonts built into the PDF format are Latin-only, which is why so many stamping tools turn СЕКРЕТНО or GİZLİ into boxes and question marks. nopa sidesteps that by drawing your text with the browser’s own type rendering and placing the result on the page as a transparent image, so Cyrillic, Turkish, Greek, and CJK come out exactly as you typed them.
How it sits on the page
One mark per page: bold, grey, about 30% opaque, angled at 45° and scaled to roughly 70% of the page width, centered over the content. It is a single diagonal stamp rather than a tiled repeat, so a reader can still work through the page underneath. The same mark goes on every page of the document — there is no way to watermark only pages 4 to 9.
A label, not a lock
Be honest with yourself about what this achieves. The watermark is an ordinary layer of page content, so anyone with a proper PDF editor can lift it off, and nothing about the file is encrypted or restricted. It is the right tool for making sure a draft is never mistaken for the signed version, and the wrong tool for stopping someone copying your work.

Pertanyaan
Does the watermark cover the text?
It is semi-transparent, so the page stays readable underneath.
Can I use my own language?
Yes — the watermark renders any script, including Cyrillic and Turkish.
Can someone remove the watermark?
Yes, with a PDF editor. It is drawn as content on the page, not baked into the pixels, and the file is not encrypted. Treat it as a clear label rather than as copy protection.
Can I watermark only some pages?
No — the text goes on every page. To mark a section only, extract those pages first, watermark that file, and merge it back with the rest.
