About
Just PDF Watermark is a focused iPhone app for adding text watermarks to PDF files before you send, upload, or store copies.
Choose a PDF from Files, write the purpose of the copy, preview each page, and export a new watermarked PDF. Your original document stays untouched.
Use Just PDF Watermark to:
- Add repeated diagonal watermarks across every page
- Add one large centered watermark when a simple stamp is enough
- Adjust text, opacity, size, and color
- Preview pages before export
- Create a new marked copy for sharing or saving to Files
Watermarking runs on device using Apple PDF tools. The app does not require an account and does not upload your documents to a server.
Built for everyday documents such as rental applications, bank statements, ID copies, visa paperwork, draft files, and other PDFs that need a visible purpose mark before sharing.
