Why it's useful

A watermark protects a document from misuse and marks drafts and samples. The semi-transparent diagonal line is visible but doesn't get in the way of reading.

Great for contracts, portfolios, price lists and presentations. The text is drawn in your browser and supports any alphabet; the file is never sent anywhere.
