Add Watermark to PDF - Overlay Custom Text Seals Safely
Stamping documents with custom text overlays is a great way to safeguard intellectual property, label drafts, and discourage unauthorized sharing. PDFMinty's watermark tool lets you apply customizable, transparent watermarks to all of your PDF pages locally, right inside your web browser, without relying on vulnerable cloud servers.
Full Overlapping Customization Settings
Our interface offers extensive styling and positioning options. Easily type in custom labels like 'DRAFT', 'DO NOT COPY', or 'CONFIDENTIAL', and adjust text size, opacity, and rotation angles. The stamp is written directly to the document's vector paths, preventing simple removals while keeping your text sharp and legible.
Step-by-Step Guide to Watermarking PDFs Offline
- Select and drop your PDF into the local workspace engine.
- Type your watermark text into the text field.
- Fine-tune the horizontal position, opacity, font size, and rotation angle using slide controls.
- Click 'Apply Watermark' to stamp all sheets, and download the finished file.
Designed for Strong Data Privacy
Traditional PDF editors require uploading documents to remote cloud farms, which can expose private files to data leaks. PDFMinty protects your privacy by processing files locally. Your contracts, mockups, or financial files remain on your device, ensuring complete security.
