Add a watermark to any document

Watermarking is good practice, but some organisations require an unmarked document: banks, government offices, notaries. Check before you send.

• The file you get back is a PDF.
• Your files are never written to a disk: everything happens in memory.
• The watermarked document is erased on the first download, and after one minute at the latest.
• QR codes and barcodes already on the document are left clear, so a counter clerk can still scan them. So is the machine-readable strip of a passport, where it is detected.
