No, the tool works entirely within your browser. Your file never leaves your device, and all operations are performed locally.

In this tool, the watermark is "burned" onto the page as an image. Removing it later requires specialized techniques. We recommend saving a copy of the original file before applying.

The tool relies on converting pages to images, so it may not work with some strictly protected files. In most cases, it will work normally.

Since the tool converts pages to high-resolution images (JPEG) before re-assembling them into a new PDF, quality may differ slightly from the original, but it remains excellent for general use and printing.
