Para que serve
This tool opens your PDF in the browser, draws the same diagonal text watermark onto every page, and saves a new copy. It is useful for drafts, confidential files, review copies and internal documents that need a visible label before sharing.
Como usar
- Choose a PDF file from your device.
- Enter the watermark text and adjust size or opacity.
- Add the watermark and download the new PDF.
Privacidade
Esta ferramenta roda inteiramente no seu navegador. O que você digita nunca é enviado, salvo ou compartilhado — fechar a aba já remove tudo.
Perguntas frequentes
- Is my PDF uploaded?
- No. The file is read and rewritten in your browser tab with pdf-lib.
- Does it change the original file?
- No. The original file is only read; the watermarked version is downloaded as a separate PDF.
- Can I remove the watermark later?
- This tool writes visible text onto each page. Keep the original file if you may need an unmarked copy.
