Use native searchable text or embed a PNG/JPEG logo without changing the source PDF.

Choose a page anchor, rotation, opacity, scale, repeated pattern, and whether to skip the cover page.

Watermark content is added as PDF overlay content; existing pages remain native and searchable.

The source and selected logo stay in this browser and the original file is never overwritten.
