Can a watermark be removed?

The watermark is drawn into each page, so it cannot be switched off in a PDF reader. Like any visible watermark, determined editing could still remove it — it deters casual copying rather than securing the file.

Watermark ideas

CONFIDENTIAL — internal documents and contracts under negotiation.
DRAFT — versions that are still being reviewed.
COPY or SAMPLE — documents shared for reference only.
Your name and date — when sharing ID documents, e.g. "For XYZ bank KYC only, 21-10-2026".

Why your PDF never leaves your device

Most online PDF tools upload your document to their servers, process it there and ask you to trust that it is deleted. orrgo PDF Tools work differently: the processing code (pdf-lib and PDF.js) is downloaded to your browser and runs there, so contracts, statements and ID documents never travel over the internet.

That also makes the tools fast — there is no upload or download wait — and they keep working if your connection drops after the page has loaded.
