Standard online PDF watermark tools flatten pages into compressed images before drawing watermarks, destroying selectable text and degrading document clarity. SnapFreeTools uses native vector overlay via pdf-lib. Watermark text and logos are stamped as high-resolution layers over existing PDF pages, preserving 100% of selectable text, embedded fonts, and vector graphics.
