Everything You Need to Know About Watermarking PDFs

Protecting your intellectual property and clearly marking the status of a document are crucial steps in professional workflows. A watermark is a simple, effective way to ensure your documents are used correctly and your ownership is recognized.

Why Watermark Your PDFs?

Watermarks serve multiple purposes. They can deter unauthorized sharing of confidential files, assert copyright on your original artwork or photography, or simply inform a reader that a document is a "Draft" or "Copy" rather than the final version.

How Flipp Protects Your Privacy

Unlike cloud-based tools that require you to upload your confidential business documents to add a simple stamp, Flipp performs all watermarking locally in your browser. Your files remain completely secure on your own device.

Tips for Effective Watermarking

A good watermark should be visible but not distracting. Adjust the opacity so the underlying text remains readable. For maximum protection against unauthorized use, use a tiled pattern or place the watermark diagonally across the center of the page so it can't be easily cropped out.
