Watermark PDF FAQs
Does a watermark prevent copying?
No. A watermark is a visible label, not encryption or access control. It does not stop someone from copying, editing or sharing the document.
Are my documents uploaded?
The tools listed here process documents in your browser. Selecting a file does not upload its contents to Filestation. Download your output before closing the page; there is no cloud document library.
Are my PDFs encrypted?
The website uses HTTPS to encrypt the connection. Local processing does not automatically password-encrypt your input or downloaded PDF. No website can guarantee 100% security; use a trusted device and keep your original files.
How do I save a PDF on an iPhone?
After creating the result, use Save / Share and choose Save to Files. If a download opens a preview, use the browser’s Share control to save a copy.
