Questions
Will the PDF be uploaded?
No. The watermark is drawn onto a copy of the PDF inside your browser. The file never leaves your device.
Can the watermark be removed?
Yes, by anyone with a PDF editor. It is a layer drawn over each page, not a lock, so use it to mark a draft or a copy, not to protect a secret.
Which logo files work?
PNG keeps transparent areas, so the logo sits cleanly on the page. JPG has no transparency, so its background shows as a box. Text with characters outside the Latin alphabet is drawn as a picture, so it looks the same everywhere but cannot be selected.
Does it work on sideways pages?
Yes. Each mark is turned to match the page’s rotation setting, so it reads the right way up in a viewer on pages turned 90° or 270°.
