Hide a secret message inside a text document using document watermarking techniques. Upload a document (TXT, DOCX, or PDF) as the carrier. Enter your secret message. Choose a watermarking technique from the dropdown: whitespace encoding, zero-width characters, homoglyph substitution, line-shift, or word-shift. A password adds extra protection. Click Embed to process. The watermarked document preserves the original visible text while carrying the hidden message. ⚠️ Important: Download the watermarked document before navigating away. Save it in DOCX or PDF format. You can also export a report in TXT, CSV, XML, or HTML format.
