marklord 0.1.5

Watermarking tool for images or PDF

MarkLord

MarkLord is a tool to add a visible watermark to images or PDF files on documents (e.g. ID card, salary slips, etc. ) you need to send to third parties. If the said third party is victim of a data breach, it will be more difficult for attackers to use those documents to steal your identity. Also if you put the name of the third party into the watermark, you can identify the source of the leak, or the third party that shared or sold your files without your consent.
