Watermarked locally — never uploaded
Choosing an image uses it instead of the text. PNG transparency is preserved.
Text or image watermark
Text is the quickest way to mark a draft, confidential copy or sample. A PNG logo is better for branded documents; transparency is preserved. The angle and opacity controls keep the page readable underneath.
Frequently asked questions
Is the PDF or watermark uploaded?
No. Both stay in the browser and are combined locally.
Can I use a logo?
Yes. Choose a PNG or JPEG. A transparent PNG keeps its transparent background.
Is the watermark removable?
It becomes ordinary page content. A capable PDF editor may still alter it, so it is a visual mark rather than copy protection.
Does it work on every page?
Yes. The chosen text or image is placed in the center of every page.
