How to add a watermark to a PDF
Overlay text, a stamp or your logo on every page: useful to mark documents as confidential, drafts or copies, or to protect your creations with your brand.
Select or drag the PDF.
Choose text or image. For text, type your own or use a quick stamp (CONFIDENTIAL, the date…).
Adjust position, opacity, size, color and tilt with the live preview.
Click Add watermark and download. The watermark is applied to every page and the original text is kept.
What is a watermark for?
Mark as confidential
Add "CONFIDENTIAL" or "DRAFT" diagonally to make clear how the document should be handled.
Protect your logo or authorship
Place your logo or name over the document to make it harder to use without permission.
Date or stamp documents
Add today's date or a stamp like "COPY" or "ORIGINAL" for internal control.
Brand your reports
Place your company logo, very faint and tiled, to give your PDFs a professional look.

The watermark is added as another layer of the PDF, so someone with editing tools could remove it. It isn't foolproof protection: it's meant to deter and to make the intent clear (confidential, draft, authorship…), not to lock the document down.
Yes, the watermark is added to every page of the document with the same settings. You can preview each page with the arrows before downloading.
No. The watermark is added vectorially on top of the content, without rasterizing or recompressing the document: the original text is kept and can still be selected and searched.
No. The document is processed in your own browser and is not sent to JapalTools or anyone else. When you close the page, no copy remains outside your device.
