Need per-recipient watermarking?
This tool stamps a single watermark across all pages. Vulta Transfer personalises each copy — the recipient's name, the date, and a unique reference stamped on every page — delivered as a time-limited link with download tracking built in. Useful for client deliveries, licensing, and proof of who received what.
