Add custom text watermark to PDF pages
Last updated: 2026-10-08
Overlay a diagonal text watermark on PDF pages. Enter the wording and choose its opacity before processing. Watermarks are visible page content, not encryption or access control, and do not prevent copying. Review long text on small pages and keep the original file without the watermark.
